Hi Bruce,

I did put a messagebox in the event to see. No message. The grid is a basic grid. I put it on the form and set the columncount to 11. The code for the Valid event I put in the textbox.valid for the correct column. All other properties like controlsource's, readonly, width etc. I set in a Method of the form.
.SETALL("RESIZABLE", .F., "COLUMN")
.SETALL("MOVABLE", .F., "COLUMN")
.SETALL("READONLY", .T., "COLUMN")
.SETALL("READONLY", .T., "TEXTBOX")
.SETALL("ALIGNMENT", 2, "HEADER")
.SETALL("FONTBOLD", .T., "HEADER")
.SETALL("FORECOLOR", RGB(0,0,255), "HEADER")
*!* This is the column I want the event.
.column6.READONLY = .F.
.column6.ENABLED = .T.

I hope the above block will help.

Mike
