OnSheetBeforeRightClick property (ExcelListener).


f the user right clicks at any Excel cell then the context menu pops up. The Excel fires the "before right click" event before it displays the menu. The property OnSheetBeforeRightClick provides facilities for trapping such event.

The signature() method reveals that the event handler is expected to accept two arguments and return a boolean value. If the returned value is true then the event would be canceled and the menu would not be displayed.

We insert the event handler as shown below.
