Question

I am trying the following:

// Key to send   
 var key = Key.F2;       
// Event to send                         
var routedEvent = Keyboard.KeyDownEvent; 
TreeControl.RaiseEvent(
               new KeyEventArgs(
                Keyboard.PrimaryDevice,
                PresentationSource.FromVisual(TreeControl),
                0,
                key) { RoutedEvent = routedEvent }
            );

But I can’t simulate F2 programmatically this way though TreeControl has keyboard focus and if I press F2 immediately after manually it works fine. Please help.

I am trying to call this code in the moment OnItemSelected handler is called (not always, when necessary).

Answer 1

Initially posted code is right and I figured out that it simulates F2 press correctly for treeview. Just another problems not related to this prevented me from seeing this.

When I tried to simulate F2 click from OnItemSelected handler it didn’t work but the same from LayoutUpdated handler works fine.

So the treeview needs to be fully updated to be ready to accept key presses.
