about inherits custom control

hi all
i am trying to make a custom control in specify a button with an image
so i have googled around finding the good article on MSDN where it is
explain how to make a control which behaves like a button
(http://msdn2.microsoft.com/en-us/library/aa446518.aspx)..
this custom controls inherits from Control
and override the onPaint methods...this is good but this is quite more like
an image that you can click..

iìd like to have a button with an image over it but with the shape of the
button..so i have changed the code inheriting from Button...
but in this way i can see that the onPaint event never fires..so the code
which calls the drawing logic never executes

i hope i am clear

Hi,

In your OnPaint overrited method, did you call the OnPaint method of
your mother class ?

protected override void OnPaint(PaintEventArgs e)
{
base.OnPaint(e);
// Your code
}

Control all work, only if i inherits from the class Button the event doesn't
fire...
