Mark,

>Let me, please, ask you how to get the name of the column (or header) that when clicked fired the OnHeaderClick method?

I don't know if the solution I found so far is a good one (perhaps there should be a more adequate one if I knew all the intrincacies of grids/columns/headers), but in order to have click event fired (and actions taken) for some (specific) columns, I did:

 Procedure Header1_Click
*          ------- -----
           Messagebox (ThisForm.grdTestGrid.Column1.Header1.Caption + " was Clicked")
 EndProc

 Procedure Header2_Click
*          ------- -----
           Messagebox (ThisForm.grdTestGrid.Column2.Header1.Caption + " was Clicked")
 EndProc

 Procedure grdTestGrid.Init
*          ----------- ----
           BindEvent (This.Column1.Header1, "Click", ThisForm, "Header1_Click")
           BindEvent (This.Column2.Header1, "Click", ThisForm, "Header2_Click")
 EndProc

Sounds reasonable?
