I've set NCanvas.AllowFocus to true, along with .AllowMouseCapture and .AllowDrop and .AllowTabStop. I've also provided a FocusDecorator by specifying a color and stroke width. (This works occasionally but I'm not sure what's triggering when this does or doesn't appear) I'm using the NCanvas.GotFocus and LostFocus events to determine if focus has been achieved. My real interest is using the KeyDown event. I find that I can tab into the canvas from the NTab parent, and then all the events fire as required. But I cannot focus the canvas simply by clicking on it, or by calling NCanvas.Focus(). What am I missing? Tags AllowFocus Focus GotFocus LeaveFocus NCanvas

Calling SetFocus from the MouseDown event of the canvas works fine, and the FocusDecorator seems perfectly consistent now too. I spent hours trying to figure this one out. And then solved it within minutes of posting on this forum - d'oh!
