i have a problem with a RadTreeView i do not know how to deal with.
I have a TreeView with a HierarchicalDataTemplate.
I poulate the tree by assigning a List<myClass> to its ItemSource.
SelectedItem is set at start and then in SelectionChanged eventhandler.
Everythign works as it is expected, unless i try to navifate not by Mouse but Keyboard.
KeyDown and KeyUp result in the following error:
bei Telerik.Windows.Controls.RadTreeView.HandleUpArrowKey(KeyEventArgs e)
bei Telerik.Windows.Controls.RadTreeView.HandleKeyDown(KeyEventArgs e)
bei Telerik.Windows.Controls.RadTreeViewItem.OnKeyDown(KeyEventArgs e)
bei System.Windows.Controls.Control.OnKeyDown(Control ctrl, EventArgs e)
bei MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)
repectively get_NextItem() in the first line.
what can i do to avoid that?
This happens in all TreeViews that are populated that way, as far as i can see.
