What is the best way to present a menu in your application? - winforms

What do you think is the best way to present a hierarchical list of functionality to users within your traditional WinForms application? (A menu system - Assume functionality can be split into a small number of modules and sub-modules but with no fixed depth in terms of those sub-modules).
Do you like the traditional drop down menu system, ribbons, docked toolbars, a treeview approach or any other innovative ideas?

An important thing to consider in your design is Usability vs Discoverability.
The best solution depends strongly on who you users are. The UI requirements for a kiosk application for tourists in a city centre are very different to those for a control screen at a power station...

I often have a toolstrip docked on top for those functions that is most used. And all other as drop down menues with hotkeys set.
If I have a list that can contain different types of items I use a bottom docked toolstrip that change its content depending on the selected item in the list. That way I only have buttons/icons that is relevant for the task and not a bunch of disabled buttons irritating the view.
I also add a context menu for the items that automagically fills with the same choises as the bottom toolstrip. That way I give a faster way to get to the "action" without having to move the mouse down to the bottom of the screen.
I really hate the ribbon-thing (as a user) so I dont use it as a programmer in my projects.

In my opinion the best way is to make sure everything can be done in several ways.
Menus
Keyboard shortcuts
Toolboxes ...
So the user can choose it's way around.
What I really like to see in more application is that a menu or option is directly attached to the selected item (control) a user is looking at. And of course the menu is in context with the given content.
I have implemented this in my open source project Monex and I really like using it myself. Just look at this screenshot.

You could always opt for the increasingly ribbon control. Microsoft/Office interfaces have a habit of becoming the user's expectation of norm (eventually).

Menubars, toolbars, and Ribbons are used for commands, where the user selection of an item acts on a data object displayed in the window or the application as a whole. Which one you use depends primarily on the number of commands in your app.
Toolbar alone: About 20 or fewer commands. Provide both icons and text labels for each command button. Represent the hierarchy by separators. Have no more than two levels –flatten your hierarchy accordingly.
Menubar with toolbar: Over about 20 but less than about 1000 commands. Up to twenty menu items on a single menu (using separators) is generally better than cascade menus –flatten your hierarchy accordingly. Common commands should have accelerators. Generally limit your toolbar to no more than 30 of the most commonly used commands, primarily commands otherwise only accessible from within a dialog box. Consider not having toolbar controls for menu items that have accelerators –one good means of expert access is often sufficient.
Ribbon: Over 1000 commands. A Ribbon is little more than putting different menubars-and-toolbars on separate tabs. To work well, the tasks associated with each tab (the top of your function hierarchy) should be non-integrated –users relatively rarely switch from one to the other. The Ribbon is also tends to be more effective for promoting discovery of advanced features at the price of discoverability and efficiency of basic features.
Check if items in your function hierarchy may be better represented as attributes rather than commands. Commands carry out a process, such as Open, Find, and Copy, while attributes change specific characteristics of something, such as Font, Size, and angle of view. Attributes are set by field controls within your window (e.g., text boxes, check boxes, and dropdown lists) rather than menu items, toolbar controls, or Ribbon controls.
A window-full of such field controls (or other representations of data objects) is a content block. Tree controls may be used to control what content block is shown. Like tab controls, they are preferred over multiple windows when the user frequently switches among the content blocks and does not compare content blocks. Trees are preferred over tab controls when the amount of content will not fit in a single row of tabs.
Do not have any empty nodes in your tree. Anything the user clicks on should display a full pane of content –flatten your hierarchy accordingly, even going to the extreme of using a list box rather than a tree.
If users tend to select one content block, complete a task there, then leave your app, then consider a “home” page displaying a full-page menu of all the content blocks, possibly spatially arrange according to your hierarchy, each accessible with a single click.

In my opinion there is no definite answer to your question. It always depends on the menu you are presenting to the user and the users that are expected to use the application
A menu with standard/common functionalities is probably best presented Office style meaning drop down menus or the new Ribbon style.
A menu with custom functionality and, as you state multiple modules and submodules with different depths, is often best presented as a TreeView-like menu.
Looking from the point of the user, a typical user will do just fine with a standard menu whereas a more advanced user won't mind more advanced features like keyboard navigation or possibility to hide/show the menu or dock it to the other side of the window.

When to use custom user controls

I've got a massive UI that I'm designing. The way that my employer wants it, there are at least 100 labels. Now, I've always thought that in cases like this, breaking up the UI into smaller custom controls was the ideal way to go. However, someone recently told me that custom controls are really only for code re-use. What is the actual suggested practice for this?
EDIT
The finished form will look like this:
Now, I'm using WPF for the UI, and I'm thinking of breaking this down into smaller bits.
Based on your image i see some repetitions, each of this repetitions could be a custom UserControl
But it depends on the usability is it easier to write a custom UserControl so do it but if it would reduce the readability of your code and it also adds additional complexity don't do it
here are an example of what could be separate UserControl's
the green ones are possible useful encapsulations of logic
the orange ones maybe need some not market stuff (don't know enough about your software)
the red ones are the maybe's based on the intern use (from the visual part they are repetitions so the should custom UserControl)
Since your UI is read-only, I'd suggest using a grid.
Are you new to WPF? To break the View into bits WPF offers you CustomControls and UserControls. They are two very similar things yet completely different from each other. CustomControls are Buttons, Labels, TextBoxes, DataGrids...etc. They are basically simple stand-alone controls. UserControls are groups of stand-alone controls serving a purpose such as example a Button and a ComboBox next to each other so user can select something in ComboBox and confirm that by clicking the Button.
If you wish to display data from database I suggest you DataGrid which will give you a table-alike look with rows and columns and all that. If you wish to place few buttons next to DataGrid on which the user may click to insert a new row or to edit a certain cell then I suggest you to wrap all that with a UserControl which you can reuse in other places where you have to display and change data from database too.
You should be using a datagrid and can customize its template to render individual cells as Textblock (lighter version of Label) from a rendering perspective. The main difference between Textblock and Label is very minor things such as access keys and disabled state behavior. But from a WPF object hierarchy - Textblocks are much lighter. But besides that point - from your employer perspective - once you have customized the grid template and render them (so as they look as textblocks/labels) - your employer should have no problems.
Also as somebody suggested above - if you want to logically break sections of the UI since they maybe coming from a different table in db - then User controls is the way to go (for maintainability of code)
Let me know if you are looking for more technical details or need help further technically.
There is nothing wrong in making and using custom controls or user controls or defining some data templates which will be reused depending on how your data is organized.
For sure the UI looks pretty messy and some sort of grid should be used with templates for example where there is similar data. I also have the suggestion and first think about the data and the functionality before starting and let the UI be driven by that. For sure you will the reuse controls/templates. If you think in front on the model and behavior the UI can afterwards more easily changed.
Create your viewmodel correctly, implement the functionality in commands, use bindings, after that the UI will come naturally, reuse controls, use several grids, make the UI more user friendly using several regions, tabs, windows or anything that makes the user more comfortable.

Creating lots of user controls in WPF?

Is it normal in a WPF app to create a lot of user controls in order to separate concerns that would otherwise be crammed in a single window with a huge XAML hierarchy? I'm finding that I keep making new user controls, even though I don't intend to reuse them, just so that each of my sub-components has a separate task. I'm also giving each of them their own view model, instead of binding things to properties on one master view model.
Is this normal? I feel like from a code cleanliness perspective I'm doing the right thing. But from a WPF perspective, I feel that this can't be right.
For example, let's say you have a list on the left side of the window, and when you select an item, it changes what's displayed on the right side. There are also buttons above your list to manipulate it, adding and deleting items for example. I would be inclined to pull that whole list out as a UserControl, which would contain just the list and the control buttons above it. Then the main window would just include my new control.
Am I going overboard?

Complex .Net 2.0 Windows Forms control: where to start?

In order to make a convenient UI for an .Net 2.0 Winforms application I am working on, I have need for a control that I'm pretty sure goes beyond the "out of the box" behavior of any standard control. A mock-up of what I'm trying to achieve follows:
Mock up http://www.claware.com/images/temp/mockup.png
Essentially, this part of the application attempts to parse words into syllables from tribal languages (no dictionary to refer to; any and all unicode characters are possible.) By the time the user gets this far, he has already defined the vowels / consonants in his language and some other configuration. There is then an iterative process of (1) the application guesses which syllables exist in the language based on some rules, (2) the user refines the guesses, selecting the correct parsings or manually parsing a word, (3) the application "learns" from the user's feedback and makes smarter guesses, (4) repeat until the data is "good enough" to move on.
The control needs to present each word (the grey headers), then all the syllable break guesses (the white areas with dots separating the parts of words.) There is also a way to manually enter a parsing, which will display a text area and save button (at the bottom of the mockup.) When the user hovers over a guess, the background changes and "accept / reject" buttons appear. Clicking on the accept, or entering a manual parsing, removes the entire word from the list. Clicking the reject button removes just that item.
I'm by no means 100% sold on the formatting I have above, but I think you can get a general idea of the types of formatting and functional control I need. The control will also scroll vertically--there may be thousands of words initially.
My question for you experienced WinForms developers is: where to start? I would really, really like to stay within the .Net core framework and extend an existing control as opposed to a third-party control. (At the risk of starting a religious war: yes, I suffer from NIH-syndrome, but it's a conscious decision based on a lot of quick-fix solutions but long-term problems with 3rd party controls.) Where can I get the most "bang for my bucK" and the least reinventing the wheel? ListView? ListBox? ScrollableControl? Do I need to go all the way back to Control and paint everything manually? I appreciate any help that could be provided!
[Edit] Thanks everyone for the ideas. It seems like the most elegant solution for my purposes is to create a custom control consisting of a FlowLayoutPanel and a VScrollBar. The FlowLayoutPanel can contain instances of the custom controls used for each word. But the FlowLayoutPanel is virtual, i.e. it only contains those instances which are visible (and some "just out of scroll"). The VScrollBar events determine what needs to be loaded. A bit of code to write, but isn't too bad and seems to work well.
I would look at the TableLayoutPanel and FlowLayoutPanel controls. These will let you organize a series of controls with moderate ease in a vertical fashion. I would then create a UserControl that consists of a label and 2 buttons. The UserControl will expose properties like Text and events that are exposed for the button clicks.. For each entry in the list, you will create an instance of the UserControl, assign the text value, and handle the click events. The instance will be placed in the Table/Flow panel in the correct order. Both of those layout panels do allow for inserting items between other items so you can add/remove items from the list dynamically.
Edit:
Given the length of what you are trying to render, I would consider using the DataGridView and do some custom rendering to make it perform how you want it to work. Using the rendering events of the DGV you can merge columns, change background colors (like highlighting the dark gray lines), turn on/off the buttons, and handle changing the grid into edit mode for your rows to allow modification or inserting of new values. This method would easily handle large datasets and you could bind directly to them very easily.
Well, this certainly looks like a candidate for a custom component that you should be creating yourself. You can create this using standard .Net drawing commands along with a text-box, and a regular button control.
Now you want to find out where to start.
Create a Windows Forms Control Library project.
Drop in the textbox and the button control.
The panel drawing code should preferably be done by code. This can be done using the regular GDI+ commands.
Edit:
Here's another idea, and one that I've practically used in my own project with great success.
You could use a web-browser control in the app, and show your data as html. You could update the source of the web-browser control based on the input in the textbox, and clicking on the links in the web browser control will give you the event that you can trap to do some action. Your CSS will work.
I used this technique to build the 'desktop' in an app I made called 'Correct Accounting Software'. People loved the desktop so much that it is one of the best loved features of the app.
Here's how I would do it:
Create a custom control. In this custom control, have a ListBox atop a LinkButton, and when the LinkButton is clicked you can make it give way to a TextBox. The ListBoxes will have the top row unselectable... you can probably get the rest from there. When you get your list of words, fill a Scrollable of some kind with one control for each word:
(foreach String word in words){
myScrollable.add(new MyComponent(word));
}
From there, I'm not sure what you want to do with the boxes or the data, but that's my initial idea on the UI setup.
Use the WebBrowser control and generate the HTML markup into it using DocumentStream or DocumentText.

Best way to show screens to user on application

I'm developing a Winforms application which has been running for years with an explorer view (TreeView left, screen right). I means that:
All the screens have an hierarchy organization
All the nodes on TreeView have one and only one screen related.
A screen gets activated when a node on treeview gets selected.
One of the advantages is that the user has an ordered stucture and one of the inconveniencies is that with hundreds of screens the user gets confused.
I see other options: use classical menus, use tabs or a mix of everything.
Any advice for a good way to show a lot of screens to user in a user-friendly way?
Update: I'm changed "hundreds screens" by "a lot of screens". The most important thing is not show all at time but that the user can find what they need easily.
Update2: In this proposal, the user only see one screen at time.
Update3: I'm talking about handling multiple screens not showing multiple screens. No MDI, only one ontime.
I have used other applications similar to this is the past, and the major problem is trying to find the exact screen you want. There are two common solutions to this problem, shortcut codes and favorites menu.
With the shortcut codes, allocate a short code (5 or 6 characters) to each screen. The user then inputs this shortcut code into a text box which will then jump to the correct screen. Users will create their own list of often used codes.
For the favorites menu, allow users the ability to be able to create their own menu list in the structure they want. They will find things easier, if they organize it themselves.
Why do you need to show so many seprate screens at once? Why not just show the screen for the currnetly selected node, why are all needed at once?
If it is all tabular data is is probably too much to be consumed all at once, if it is graphical data, could it not be combined?
There may be a valid reason to show all the data at once or there may not, hard to tell from what is provided in your question. With that said, better to keep it simple than overload the user. MDI apps are never easy to use.
Tabs may work for a small set of items but still is not a good UI for hundreds of items.
If you are only showing one element at a time, out of hundreds possible on the tree nodes, then that is fine. The one screen showing at a time would be contextual to the item selected as the user moves through the nodes. Think of the Outlook approach where what is selected in the left pane is displayed in the right pane in whatever form fits the data being displayed.
Have you considered the Office Ribbon?
The Ribbon gives you a lot of flexibility on how to show and
organize functions and it's highly visual.
Here is a good link about the Ribbon and also here
To use the Ribbon you have to license it from Microsoft. You can do that online.
Providing the user with ketboard shotcuts is usually a good thing too.
I also like to provide the user with an "autocomplete" field on the menu
so that they can can find the function by name (or part of it) and be
able to navigate directly to where they want to go.
I general I find trees to be a bad idea, especially if your "hierarchy" is of a small fixed depth.
If you have a small fixed depth, consider replacing the tree with a list. At the top of the list can be drop-downs for filtering based on the node-level properties. It will use up less screen real-estate because it is vertical-only, with no horizontal component.
Clicking on an item can display it in the view (like currently), but it may be a good idea to allow a user to double-click on more than one item which could launch more windows, or tile with the existing displayed items. (I am assuming that currently, the user only sees a single detailed view at once in any given window.)
Actually, it’s hard to beat a hierarchy for organizing large numbers of items. I wouldn’t favor a classical pulldown menu for vast numbers of windows because it would be even harder to keep track of where you are than in a tree (e.g., a tree lets you look in multiple branches at once). But here’s a few alternatives:
I’m not clear how you ended up with so many windows, but maybe it comes from combinations of classes, views, content, and detail, or maybe it comes from using a task-centered UI structure for something far too complex (I’ve more on that at http://www.zuschlogin.com/?p=3). For complex apps, you want a different primary window for each significant class of data object (e.g., invoices, employees). These are listed on one menu, and typically there’s few enough (15 or less) that it can be single non-cascading pulldown menu. The content of each window is set by a separate menu, perhaps by a menu item that opens a dialog that may include a list box (like an Open dialog) or other controls for querying/searching. The “view” of each window (how the data objects are shown, e.g., table versus form) is set by menu items in the View menu. Details for any given object in a window can be shown in a separate pane within the window in a master-detail relation, essentially turning you data objects into a menu for details. A single window can have multiple detail panes for the user to open and close to select the specific detail to show. Tabs may also be used within a single pane to fit subdivisions of content.
You say it’s not important to show all window options at once, but often showing all options at once makes it easiest for users to find what they need. Maybe you need a “home” window that lists all the other windows in organized, labeled, and separated categories. This is will be easier to use than the tree if your users select a window then stick with it for most of the session. Your tree is better if there's frequently selection of windows throughout the session, owing to the overhead of getting to the home window. If all windows/options don’t fit on a single home window, then show only selected common windows for each category on the home window and provide a button or link to show an exhaustive list.
If you’re talking 100’s of windows, maybe you should have Search, perhaps in addition to a menu-based browse approach to getting to a window.
In any case, providing easy access to the few most commonly used windows is a good idea. Such windows can be explicitly selected by the designer, based on user research, or selected by the the user (favorites), but it also typically works well to make it automatic with an algorithm that uses some combination of frequency and recency of use.

Windows Forms Application Performance

My app has many controls on its surface, and more are added dynamically at runtime.
Although i am using tabs to limit the number of controls shown, and double-buffering too, it still flickers and stutters when it has to redraw (resize, maximize, etc).
What are your tips and tricks to improve WinForms app performance?
I know of two things you can do but they don't always apply to all situations.
You're going to get better performance if you're using absolute positioning for each control (myNewlyCreatedButton.Location.X/Y) as opposed to using a flow layout panel or a table layout panel. WinForms has to do a lot less math trying to figure out where controls should be placed.
If there is a single operation in which you're adding/removing/modifying a lot of controls, call "SuspendLayout()" on the container of the affected controls (whether it is a panel or the whole form), and when you're done with your work call "ResumeLayout()" on the same panel. If you don't, the form will have to do a layout pass each and every time you add/remove/modify a control, which cost a lot more time. see: http://msdn.microsoft.com/en-us/library/system.windows.forms.control.suspendlayout(VS.80).aspx
Although, I'm not sure how these approaches could apply when resizing a window.
Although more general than some of the other tips, here is mine:
When using a large number of "items", try to avoid creating a control for each one of them, rather reuse the controls. For example if you have 10 000 items, each corresponding to a button, it is very easy to (programatically) create a 10 000 buttons and wire up their event handlers, such that when you enter in the event handler, you know exactly which element you must work on. However it is much more efficient if you create, lets say, 500 buttons (because you know that only 500 buttons will be visible on the screen at any one time) and introduce a "mapping layer" between the buttons and the items, which dynamically reassigns the buttons to different items every time the user does something which would result in changing the set of buttons which should be visible (like moving a scrollbar for example).
Although, I'm not sure how these approaches could apply when resizing a window.
Handle the ResizeBegin and ResizeEnd events to call SuspendLayout() and ResumeLayout(). These events are only on the System.Windows.Form class (although I wish they were also on Control).
Are you making good use of SuspendLayout() and ResumeLayout()?
