No, you can't, because you can't generate the PaintEventArgs. Instead, call Invalidate(), which will force a paint event to be properly called.

Sure, go ahead, we learn more from getting things wrong than by getting them right the first time, or by asking and being given the answer.

This is not correct syntax. You'd have to write
PaintEventArgs e = new PaintEventArgs();
// set up e's properties
// ...
OnPaint(e);but like the others suggested, this is really not the correct way of doing things. Just replace the call to
OnPaint(...);withInvalidate();and you're done.Regards, mav -- Black holes are the places where God divided by 0...
