I have a set of tabbed views that correspond to RadTreeViewItems so that when the treeViewItem is clicked, the correct tab is selected and when a different tab is clicked, the correct treeViewItem is selected. I am binding to the RadTreeViewItem.Command property so that I am notified when the user clicks on the treeViewItem..
The problem is that programmatically changing the IsSelected property of a treeViewItem does not "reset the active" treeViewItem, meaning that the original treeVIewItem will not fire its Command when the user clicks on it. Visually, everything looks correct, but I don't know how to notify the treeview that I programmatically changed the active treeViewItem.
Example, the user clicks on treeViewItem1 --> treeViewItem1 highlights and then highlights tab1. The user then selects tab2 --> tab2 highlights and treeViewItem2.IsSelected is set to true. When the user clicks back on treeViewItem1, its Command is not fired.
Additionally, I do not want the treeViewItem that is programmatically set as IsSelected to fire its Command. That would cause in infinite loop in my current code.

Working with a group of programmers in a scrum team is FUN! It seems that some other code was setting the IsEnabled flag to false but the GUI item was not grayed out so I did not know it was disabled.
