Draw on top of child control

Question

How to draw on top of a child control with another control-

I have a user control A, that contains usercontrol B and C. C is the last control in the ControlCollection class of A.
All A, B and C have their own paint events.

UserControl A contains Usercontrol B. UserControl B contains a Panel and a button.

UserControl C (a transparent control) is used to represent an invalid state of A. If A is invalid, C is drawn with (X) mark in red color.

Everything works fine at design time. At run time, C is drawn behind B. I want to draw C on top of B.

I have tried many combinations, like sending B to back, bringing C to front, calling A.Invalidate in B's paint event etc but with no success.

Any help is appreciated

Answer 1

Hello,
Do you mean that you want Usercontrol C appears above usercontrol B?
I have invested your problem. But on my side, which appears on the top is decided by which is put last. And you could also put C above B, then put B on A, this must result in C on top of B.
Maybe I misunderstood you, please correct me.
Thanks

Answer 2

You are correct, I want to UserControl C above usercontrol B.
In the UserControl A's control collection, C is the last control in the list.
Still B is drawn on top of C at run time.
At design time the order is fine. C is drawn on top of B
