Its possible, but you cannot subclass either columns or headers visually only programmatically.

>I'm doing a grid class that I'll use in different forms with different columntcounts.The columntcounts of each form is in the init-event. I need to create a "column class" or something like that because I want to add my code to de mouseup event(header). Another way to explain the same: I need that the column's header inherit the method (mouseup). Is it posible?
