Hi Mayank,
Yes, you need to capture the RightClick event with BeforeAction = true (before the event happens) and set the BubbleEvent = false. This will stop the right click event from being processed.
In any case that won't fix your issue by itself. The Copy and Remove are menus. So they can be invoked from the menu bar (I believe it's in the Data menu).
You can disable the menus for the form in question using form.EnableMenu("menuId", false); or in the form XML (if you are using XML to load the form).
Best regards,
Pedro Magueija
