Row edit API methods not working

[sprucely]

I can initiate the insertion of a new row by pressing [insert] or clicking on the "Click here to add..." row, but RadGridView.BeginInsert() does nothing. Likewise, I can cancel the addition of a new row by pressing [esc] twice (once for the cell and once for the row), but RadGridView.CancelEdit() does nothing. CancelEdit() also does nothing for a non-new row in edit mode.

Am I missing something? I have tried just about everything short of simulating the keystrokes, which I will try if I can't find a solution that is less of a hack.

Correction: CancelEdit() does work for non-new row in edit mode.

But that still leaves me with how to handle the new row. I have tried two hacks with no luck...
sending key event...

var keyEventArgs = new KeyEventArgs(Keyboard.PrimaryDevice,
    Keyboard.PrimaryDevice.ActiveSource,
    0, Key.Insert) { RoutedEvent = Keyboard.KeyDownEvent };
this.DataGridControl.RaiseEvent(keyEventArgs);

calling command directly...

var routedCommand = RadGridViewCommands.BeginInsert as RoutedCommand;
if (routedCommand != null)
    routedCommand.Execute(null, this.DataGridControl);

My bad. The methods are working after all. The problem was that I had inadvertently bound a second RadGridView to my view model and was calling the methods on the non-visible one.
