Hi Rodolfo,

>How do I do it?

You define it like this:

define class myheader as header

procedure click

    This.Parent.Parent.HeaderClick(this)

endproc

enddefine

Then you add it at run-time by removing the existing header and doing an addobject(). Then in your grid class make sure you have a HeaderClick method so you can add your code to the grid, this way you only need one header class kicking around, with multifunctional headers.
