I'm trying to put code in all kinds of places to handle this on a grid; so far unsuccessfully. When a checkbox is checked and user goes to the adjacent column's textbox it should be disabled. All is well unless the user simply clicks on the textbox with the mouse. It remains enabled. I've tried the textbox When, GotFocus and other places. Why won't it disable if I have code in the When to handle it?
