I have a WPF TreeView with just 1 level of items. The TreeView is data bound to an ObservableCollection of strings. How can I ensure that the same icon appears to the left
I think one of the best articles that will help you to understand the TreeView is this one http://www.codeproject.com/KB/WPF/TreeViewWithViewModel.aspx. In general, this describes a good set of patterns that can make a lot of scenarios in WPF/SL much easier.
