When changing the value of combobox1, the id of the ...
I have a C# ComboBox using WPF. I have code that executes when the combobox's gotfocus is activated. The issue is that the gotfocus event is executed every time a selection is made from the combobox.

Windows forms had a property win1.Handle which, if I recall, returns the handle of the main window handle? Is there an equivalent way to get the handle of a WPF Window?

I want to gather here the hard-to-reproduce WPF bugs along with their solution. So post them only if you have a solution for them, you can post just a link to them. I found one of these, and I put it here because I didn't found an easy way to put code on a blog yet (and I tried a few of those code formatters). Test1: Start the followin...
I am very new to WPF. The UI I was required to implement makes use of buttons that contain both an image and a textual label. Creating one of these buttons is straightforward: I set the button's content to a UniformGrid and drop an image and a label into the grid. However, since there are quite a few of these buttons in my GUI, how do I...

I have created a UserControl, and added a couple of custom routed events. The problem is these events only show up in Properties->Events when I am manipulating an instance on the art board. If I am editing the UserControl itself, the my custom events do not show up in the Events panel. Is this a limitation of Blend, or a side effect o...
