I created a derived Form class, with the constructor using GridLayout as a parameter.
How do I remove the white border(or the margin/padding) from a form object? I tried updating listItemGapInt in my theme.res but that failed to work.
Here is an example of a form taking up the screen. (I believe the border is coming from my Form, it may be from my GridLayout)
Override both Form and ContentPane UIID's in the theme and make sure they have 0 padding/margin:
Double click theme.res
Select "Theme"
Click Add on the bottom
Type in Form on the top combo box
Select Margin tab and uncheck the Derive flag. Do the same for padding
Repeat this with ContentPane instead of form
Press Save in the designer tool

I placed several panels on my form. When I clicked the central panel in the designer, the main form was what was actually selected (even though the panel should be on top of it, and the main form should not be (easily) clickable in the designer).
By the way, clicking the other panels on the form don't have this problem (all of the other panels are on top of the form).
Because of the form being clicked when I expected that I was clicking the panel, when I added several controls to what I thought was the panel (after successfully adding some labels on top of the panel), all of these controls (checkboxes) ended up on the form / below the panel, so that they don't display at runtime:
When I realized that the controls were on the form, and not on the panel, I selected the form from the Property browser, selected all of the checkboxes at once, and cut the group of them.
I then selected the main panel from the Property Browser, and pasted those cut checkboxes onto the panel. It sort of worked, but all I saw was their outline (all selected together). I used the Ctrl+Up arrow to move them in a body up on the panel, a little at a time, until they were all near the top where they belong. But then they just disappeared.
From now on I will make sure to right-click the panel and select "BringToFront" before adding any controls to that area; for now, though, I don't see the checkboxes on either the form or the panel. How can I get them back (and place them on the panel), and prevent the form from ever appearing on top of the panel (except if/when I select it from the Property browser)?
The checkboxes do still exist, although their names were changed from "ckbxAll" etc. to Checkbox1, etc. They appear on the correct panel in Form1Designer.cs, but do not display. Here is how they are represented there:
// panelMain
//
this.panelMain.BackColor = System.Drawing.Color.White;
this.panelMain.BorderStyle = System.Windows.Forms.BorderStyle.Fixed3D;
this.panelMain.Controls.Add(this.checkBox21);
this.panelMain.Controls.Add(this.checkBox20);
this.panelMain.Controls.Add(this.checkBox19);
this.panelMain.Controls.Add(this.checkBox18);
this.panelMain.Controls.Add(this.checkBox17);
this.panelMain.Controls.Add(this.checkBox16);
this.panelMain.Controls.Add(this.checkBox15);
this.panelMain.Controls.Add(this.checkBox14);
this.panelMain.Controls.Add(this.checkBox13);
this.panelMain.Controls.Add(this.checkBox12);
this.panelMain.Controls.Add(this.checkBox11);
this.panelMain.Controls.Add(this.checkBox10);
this.panelMain.Controls.Add(this.checkBox9);
this.panelMain.Controls.Add(this.checkBox8);
this.panelMain.Controls.Add(this.checkBox7);
this.panelMain.Controls.Add(this.checkBox6);
this.panelMain.Controls.Add(this.checkBox5);
this.panelMain.Controls.Add(this.checkBox4);
this.panelMain.Controls.Add(this.checkBox3);
this.panelMain.Controls.Add(this.checkBox2);
this.panelMain.Controls.Add(this.checkBox1);
this.panelMain.Location = new System.Drawing.Point(160, 0);
this.panelMain.Name = "panelMain";
this.panelMain.Size = new System.Drawing.Size(639, 740);
this.panelMain.TabIndex = 2;

UPDATE
It turns out they ARE there, but they are invisible now (except for their outlines when I click on them):
I have a winform application that has a textbox, multiline, readonly where I display a kind of log that is refreshed each second. The text box can have more than 100 lines of text.
On each refresh, if the user scroll and selection are lost.
I need a way to allow to the user to keep the scroll and selected text.
I tried to replace only the line that changes - didn't work (using Lines property)
I tried to save the selection before update and re-select it after - didn't work.
I tried to use RichTextBox instead - didn't work.
Anyone did something like this before? Is any library (custom control) I can use instead?
Thank you.
I have some forms that use RadioButtons and Checkboxes and they work fine. But I want the user to be able to highlight(select) the text in these controls labels. Instead, when the user tries to select the text clicking on the label, it activates the control itself (RadioButton or Checkbox).
I wonder if it is possible to disable that behavior and have the user click on the icon only (circle or square) to activate it. Clicking on the label should have no effect on the control and should allow the user to highlight the label text, so they can copy and paste it somewhere else.
A possible solution would be to have no label but a plain text besides the control, but it would be nicer if I could just disable clicking the label to select the control.
I have a Region in the top left of the WPF application which I want to be my global button bar where the user chooses which screen they want to view, and the appropriate content will then be displayed in the main region. THere will also be a sub navigation region in the top right with sub-menu options within that screen, eg if the user clicked "Maintenance" from the main menu, the sub menu would show options for New, Update, Delete, Edit etc.
What I want to have is a way to create a custom menu bar by simply specifying a list of Text button names, and ICommand/Parameter pairs for the action to invoke on button click. The natural way to do this would be have a MenuButtonViewModel class with dependency properties Title, Command and CommandParameter. One more would also be needed, IsSelected, so there is some visual way for the user to see which screen you are currently on, so it needs to behave like a toggle button, but where only one button in the group can be selected at a time. I can then have a UserControl where the content of the bar binds to an ObservableCollection and uses data templates to render the button bar.
I have tried a few ways of doing this so far but cannot figure out a way that gives me the visual behaviour I want. These are my requirements
1) Button to change background to a different Brush OnMouseOver
2) When button is selected, a different Brush is displayed as the background until a new button in the group is selected, like a togglebutton IsSelected behaviour
3) Only one button in the group can be selected at a time
The ways I have tried to do this so far are
1) Extending RadioButton with my own class, adding dependency properties for command and commandparameter. Setting all controls to have the same group Id. Data template to override display of radio button to make it look like a visual button with triggers for mouseover and isselected.
This works fine, except for one thing. Once you select a radio button in a group, there is no way to deselect all options in the radio button group. So if you navigate to "maintenance" and then click the sub menu for "Countries" for example, then you are displayed the country maintenance screen. If you then go to a different area of the app and select "Deal Entry" from the main menu, you are taken to the deal entry screen. If you then click "Maintenance", it displays the generic "maintenance" content and brings back the sub menu control for maintenance, where "Country" is selected in the radio button group, but this is undesirable. When you navigate back to Maintenance, it should deselect all sub menu options, display the generic maintenance landing page content and let you select a sub menu option before displaying that screens content. The first time you load Maintenance, nothing is selected, but once you have chosen an option, then there is no way to have nothing selected again when you reload the maintenance screen.
2) I then tried extending a ListBox, styling it with a horizontal stackpanel for the content, each listboxitem is a menubuttonViewModel. This allows me to only select a single option at a time and to clear the selection when you navigate away from the page. It also lets me change the background when you mouse over each listboxitem.
The bit I can't get working with the listbox is to have the background different on the IsSelected trigger. There seems to be some trigger on the default ListBoxItem template that overrides anything you specify in CSS so no matter what trigger I put on the listboxitem or menubuttonviewmodel style, the background simply does not change. I think I need to redefine the data and content template for listboxitem, but only have it apply for this listbox, so it can't be a global template change to all listboxitems - as I want to be able to use listboxes elsewhere in the app without inheriting this behaviour.
Can anyone give their thoughts on these two approaches and how to perhaps solve the issues I'm having to make one of them work in the way I want, particularly if you can advise how I can override the content/data template for the listboxitems in my style so they do not use the default triggers, and I can get the IsSelected trigger working for me?
If I understood correctly, you would want to clear the selection on the RadioButtons from the Sub-Menu each time you navigate back from another Main Menu option.
In order to solve this, you could have every Radio Button "unchecked" by manually setting the RadioButton´s IsChecked property value to false. A possible solution could be the following:
If you want to clear any checked option from the Sub-Menu everytime you navigate to a different section of the Main Menu, you could first notify to the Sub-Menu´s ViewModel by publishing an event using the EventAggregator after selecting and clicking a different MainMenu button, from the SelectionChangedEventHandler method of the Main Menu´s ViewModel.
Therefore, the Sub-Menu EventHandler of the published event would update each RadioButton´s IsChecked property value to false, which it could be accomplished by using a "Two-Way" Binding between each IsChecked property defined on the View, and each boolean "RadioButton1IsChecked" property implemented on the ViewModel.
I hope this helped you.
I am using devexpress gridcontrol in my desktop application. But I am facing a problem with tooltip.I used the repositoryHyperlinkbutton and it has 3 buttons in it named view, edit, insert
Now I want to display a tooltip for that three Buttons. I already set the property for it.When I use single form the Tooltip work fine. but when I used that form with MdiParent at that time the Tooltip is not display.
This Problem is solved in above the devexpress 11.5 controls.
I done it.
The cells in a GridView contains no controls - they are only painted. When you click a cell, its in-place editor is created (or - in this case - the 3 image buttons). No controls = no tooltips!
