I am creating a user control that I would like to be able to generate the form entry fields based on what custom data object the form is bound to. Basically, I have a drop-down box that allows the user to pick what type of data object they are working with (user, address, etc.) That choice will bind the user control to the related data object. No big deal there. I am stuck, however, on how to generate the form fields based on the properties of the object. I feel like I have seen examples of this in WPF but am not able to find them now. All form fields will be simple label, textbox combinations in a stackpanel.
I know more detial will probably be required. Let me know what specifically you would like to know. Any help of direction is greatly appreciated.
Best,
Ryan
It sounds like you are looking for something which runtime generated, but check out the Xaml Power Toys, which will do this at design time

How could I assign a custom class (Customer, Order, etc) to a DevExpress PropertyGridControl (or native Windows.Forms.PropertyGrid) at Design Time?
The PropertyGridControl.SelectedObject's dropdown list shows only the other Controls used in the form, but not custom fields declared by me. For instance:
Dim oCustomer As new Customer
I'd like to customize MultiEditorRows, styles, etc at design time to show my object properly.
At runtime it's as easy as:
myPropertyGridControl.SelectedObject = New Customer
Any help would be greatly appreciated. Please excuse my bad english.
At design-time only components that exist on a form can be selected as the grid's SelectedObject. Of cause, you can make your object a Component descendant and drop it onto a form to select it. But, I don't think that you really need this. As far as I understand, you need to generate grid rows at design time to customize them. If so, it's better to use the Rows Page designer to manually add the required rows and customize them.
I'm developing a WPF application that contains a lot of forms (about 20 different forms)
each form is connected to a ViewModel class that usually hold a single object that the form is editing its properties.
I need to give a graphical sign to the user if he changed something like in Word when you edited the document and it tells you need to save it.
If the user edited even one property I need to show that sign.
Is there a simple way to accomplish that? I don't want to create an event for every property editor I have (there are more than 300 of them).
Why not use INotifyPropertyChanged?!
Since you are using WPF, you can opt for SourceTrigger to Property Changed.
Check here, http://www.codeproject.com/Articles/15822/Bind-Better-with-INotifyPropertyChanged to know about using INotifyPropertyChanged.
I am filling up a Stackpanel with Textboxes. Each textbox, Should display the Value Property of a Class i have written.
The number of Textboxes is always different so i can't create a databinding in the xaml file.
Are there tutorials, that show how can i archive my goal?
Edit: Thanks for the replies so far. After reading the articles i still not clear how to implement my Problem.
Here is what I'm trying to achieve:
I have an SQL Server DB and there a Table with an ID and a Value.
I now load all Values and IDs i want to display into my application. (number of loaded rows is always differnt).
I need to display a textbox for each row and display the value there and after the value is changed i write the value back to the database.
I don't know how I should query the data and than bind it to the textboxes.
I don't need an implementations, I am happy with every piece of advice I can get.
yes there are a number of tutorials out there. It sound like you are interested in datatemplating.
I would suggest looking Here on MSDN. A few tutorials on databinding in general may be useful DataBinding on MSDN
If your class, classValue, has a public property Value then just create a List and bind that to a ListBox with the item DisplayValuePath = Value. Repeater controls are used to bind to collections.
Basically I use lists to display information, these lists contain custom data items I have created, they all look similar and have some of the same controls in them, essentially they need to look the same colour, font etc. At the moment, I just seem to be repeating code over and over each time a change is needed i.e. colour.
I have been wondering if it would be a good idea to create a generic data item which all the lists use and then just collapse controls which aren't needed.
So I was going to create a user control called something like "GenericDataItem". This data item will contain all the controls that each data item would need, then use dependency properties to collapse controls not required.
My question is would this be the right way to go about this, or is there a better way?
Thanks.
Not sure I got the point, but using DataTemplateSelector could help you.
Im looking forward to writing a combobox with history. Much like address bar, only simpler(no searching, use history only). Since this is quite common, i think maybe there is a library or anything on it. I dont want to write the system from scratch(which ive been doing anyway until i realize its too much work for simple unrequired feature).
So, my question is, how can i have a combobox that can save information that user entered, manage the information that the user entered(delete, rank up/down etc).
Thanks.
i think one solution could be to define an object with hold the entered information and other information like delete command, rank value. then put this object in a observablecollection, use it as the combobox itemsource and whenever a user put something in your comboxbox update your collection in the way you want.
