MSG-BEGIN-HEADING-MENU-POPUP
This event is fired when the user starts selecting a menu item in a heading menu popup of a Grid control.
When the user clicks on the check box menu item corresponding to a column, the EVENT-DATA-1 and EVENT-DATA-2 data items contain the column number and the current value (respectively) of the check box.
When the user clicks on another menu item, EVENT-DATA-2 is not set and EVENT-DATA-1 assumes one of the following negative values:
-1
Find
-2
Copy
-3
Export
Setting EVENT-ACTION to EVENT-ACTION-FAIL inhibits the change of the check-box menu item value.
