>I'm still wrestling with this issue. I've got the validation routine in the LostFocus method for a combobox in a grid column. If the validation routine returns .f., LostFocus does NODEFAULT which leaves the combobox as the object with focus. This works fine as long as the user tabs off the combobox. If however, the user uses the mouse to select another page (for example), the focus moves to the new page. I really want the user to not be able to move focus away from the combobox until a valid entry has been made. Is this possible? If so, how?

NoDefault
ThisPage.setfocus (should be probably written as this.parent.setfocus)
This.SetFocus

I guess it would forcibly reactivate the current page, then the combo.
