I would like to use a style for the TreeViewItem in order to add some prope...

Hi I'm new to the Hyperlink control. I wish to have a hyperlink in a regular WPF window which will navigate to a URL by opening the standard browser. I have added the hyperlink, but it does nothing.

When I insert the UserControl, it shows up alright but the RichTextBoxes are disabled wi...

When I press 'Down' key, the focus moves from ListBox to the first ListBoxItem. (What I want is to make 6th item selected, regardless of the 'border') When I navigate using 'Tab', the Lis...

Weird question, but one that puzzles me a bit. In the old days when we had Terminals and DOS, applications generally only had one "window", and that was a fullscreen one.
