I need to apply some text formatting when displaying items in a WPF ListView. The text formatting is nothing too fancy just setting the background colour differently on certain strings within the text. The text does not lend itself to different columns so it's not an option to apply a style to one of the ListView columns. I'm pretty ...
I have one UserControl which has a ListView showing a list of Client objects. Double clicking one of the rows plays an animation and transitions to another UserControl which shows the list of accounts for that client. The second user control is bound to the Accounts property on the Client object. The list of accounts is loaded the firs...
How do I filter out the Silverlight documentation when I'm developing WPF application in VS2008? It's very annoying to get the help for the Silverlight version of the class when I press F1. I'd prefer not to remove the documentation for Silverlight altogether since I will need it in the future, but some way to choose between WPF and Sil...
If I have a databound form, how do I know if a user has modified it (either by typing text into a text box, or by selecting an item in a combobox)? I've tried hooking into my textbox's "TextChanged" event, but the problem is that, when my form participates in databinding, the "TextChanged" event fires, prematurely marking my form as "dir...

All the documentation and examples I'm finding online for setting Z-Index to bring an element forward in Silverlight are using a Canvas element as a container.

What do i use instead of Me.Invoke when i use wpf? ...
I want to verify that the items in my ListBox are displayed correctly in the UI. I figured one way to do this is to go through all of the children of the ListBox in the visual tree, get their text, and then compare that with what I expect the text to be. The problem with this approach is that internally ListBox uses a VirtualizingStackP...
I'm working on the toolbar for a WPF application. The icon set we are using has separate icons for normal, hover and disabled states, and I would like to use them. I was wondering what the simplest solution/normal way of doing this is? My first thought was to create a user control "ImageButton" with properties NormalImage, ActiveImage, ...
