Hmm, according to the docs that's for selecting what Field is returned when you read SelectedValue. I've gotten deeper into the issue and found that its a timing thing. When I set the ItemsSource property to the data, and then try to select an item in the TreeView, the data is there but the TreeView hasn't finished processing it. So that means the .ItemContainerGenerator class returns nulls when I try to get the TreeViewItem from the DataItem (using the ContainerFromItem method).
My code works fine if I select something from say a button event when the TreeView has finished loading the data. I can't find an event yet that I can use to indicate the data has loaded. (Unless maybe the Loaded event happens again? It seems to trigger the Loaded event when the TreeView is rendered). cheers, Stephen 2009/3/28 Jonathan Parker <[email protected]> > Just a guess but maybe you have to set the SelectedValuePath property. > > > On Sat, Mar 28, 2009 at 2:17 AM, Stephen Price > <[email protected]>wrote: > >> Has anyone had a good play with the Treeview control in the Silverlight >> Toolkit?
