Hi!

I have a textBox on a windows form.

Can i overide the textbox OnPaint directly in the form, if so how.
Or do i have to inherit the textbox control and overide it there?

Regards
Martin

Martin,

There is no native .NET way to override the OnPaint besides inheriting
it that I know about.

You can subclass the textBox and override the WM_PAINT message using
interop services.

You can use inherit NativeWindow class and attach the window handle of
the TextBox to a it. The concrete class will override the WndProc
method and handle the WM_PAINT message in it.

Hope it helps.

Moty.
 
Ok!

Thanx!

I think the easiest way to do it by inheritance. This way it's also easy to
maintain :)
