Form 1 has a transparency key for custom title bar with a background image.
I set the child forms(Inside the MDIclient) back color the same with the transparency key I set for the parent. Now its like making a hole in that area.
Is it possible to set the child form back color to transparent? so that the parent form background image visible within that form… thanks for your answers…
[Solved] my own problem.
Just for sharing..
Put this in the constructor of the child form
