Hi Herfried,
Are you asking the question for the Windows Forms button control or the
Web Forms button control?
Is there a reason for this question, this is one of the occassions where it
is exactly the same for a windowform as a webform.
The button is one of the rare controls that are very much the same on a
winform and a webform. (Has even automaticly the postback property on true).
button1.backcolor and event is button1.click
:-)))
