I’m using a RadTreeView to display a simple organization hierarchy. I have set IsEditable to true so the user is able to press F2 to edit the name of the organization. This works perfectly

My client has specifically asked for a button on each item in the treeView, which should do the same as pressing F2.

Button Click is handled in code-behind like this:

RadTreeViewItem item = GetContainer((OrganisationViewModel)((FrameworkElement)sender).DataContext);
            if (item != null)
                item.IsSelected = true;
                Dispatcher.BeginInvoke(() =>
                    treeView.SelectedContainer.IsInEditMode = true);

First line will find the item-container, and this seems to work also. The last 7 lines are supposed to mimic selecting the item and pressing F2. 

In my test example I have the following tree:

Org 1
Org 2
Org 3
         - Sub org 1
         - Sub org 2

My code works fine for Org 1 and Org 2, but for Org 3, Sub org 1 and Sub org 2, it does not work. The items will not even be selected?

Note: When i debug the code, the first code line will find the correct RadTreeViewItem, and item.IsSelected = true also updates the  treeView.SelectedContainer. I have tried with or without the Dispatcher and BeginEdit() on the item. Nothing works? 

Best regards, Simon

Hello Simon,

I cannot tell for sure why this happens at your side, I also need more of your code in order to advice you better. However, I tried this and everything works as expected. Please check out my test project and see if it can help you. Thank you in advance.
