How do you create the "gray square" in the first place. There is always the OnLostFocus Method.

The "gray square" is created automatic. For example, in web pages when a control is focused, it has a dot's line around the control.

I want to delete this square.

I was under the impression that the "gray square" was something you were putting there manually.
In this situation, just remove the focus from the control and it will go away. If something is added automatically by the system, let the system remove it.

But if I remove the focus I can't use tab key to move for each object.

This is the default rendering for the Button class. If you want to remove that, then you will need to provide your own drawing functions for the button.

You may need ButtonRenderer and this could help:

Is not any possible way to solve it with out draw again the control?

Olivier Levrey 20-Feb-11 7:57am

There is no option in the Button class that says "do not draw the focus rect", so you will have to draw the button by yourself, or live with the defaults.
Even though I never used the ButtonRenderer class by myself, you can probably call the default drawing functions and customize only the focus part.

This is the best answer, and this class is the best helper class for the purpose, my 5.
