Drawing other controls

[agent]

I'm trying to code a designer for controls for my app (not an IDE designer). I'm going to be able to move the control around and size it using the mouse. I want to prevent mouse events on the control without disabling the control. The best way I can think of this is to hijack the drawing code and draw the control into my own control.

I got it to work with the Button control: I call the OnPaint method. How? (Considering that it's protected...) I used reflection to find the "OnPaint" method signature and called it using the invoke method providing it the graphics object attached to a label control. The code to invoke the Button's paint event was in the Label's paint event.

This worked surprisingly well for the button. Unfortunately, it didn't work so well for other controls, such as the Listbox.

Using Lutz Roeder's .NET Reflector* (to decompile the listboxes drawing methods) I discovered that the Listbox does it's drawing from a method called by WndProc instead of OnPaint (like a rational control...)

Is there a way anybody knows of to cause a control, in most sane circumstances, to paint to a Graphics object that is not its own?

Do you know of a better way to obtain my long-term goal of preventing mouse events from reaching a visible and enabled control?

I'm designing this with the intention that it work with anything that inherits Control.
