C#:OnPaintBackground in Component and User Control
-
Hi all, Can i use
override void OnPaintBackgroundin custom user control?My purpose to use this method in custom user control is because i will draw the base line (grid) as image in the drawing area at the initiate state, but after that, i don't want to repaint again the background(image) when i draw some line on it. Thus, i need to override the OnPaintBackground method and disable it to fulfill my purpose. I can done it in Component,but how about in custom user control?:confused: Any tips are welcome. regards cocoonwls -

If you want to draw over default background, be sure to call base.OnPaintBackground as a first thing in your override method. If you want to draw your background completely by yourself, don't call base.OnPaintBackground at all. hope this helps
