How to draw a manually drawn control inside a manually drawn control?

Question

I have two controls in C# that I override OnPaint() to draw all the visuals myself.

I'd like to add one of those controls inside the other.

What do I put in my parent control's OnPaint() to call the child control's OnPaint() ?

Answer 1

You don't specify winforms, but that seems very likely based on your question.

You are presumably calling Invalidate() or Refresh() depending upon your heart's desire.

Refresh() on a control should make the control and its children to repaint.

If you call Invalidate(true) on a control, the child controls should also receive the invalidate message. Invalidate() without the true parameters is not recursive.
