I have a GDBG that I want to allow the user to multi select rows within a column and then perform a right mouse click action on all rows selected. I''ve got that all working fine, but my problem is how do I prevent them from selecting cells from multiple columns? Each column in the grid allows a different right mouse click action so having cells selected from multiple columns would be confusing.
What I would like to do is if the user has crossed column boundaries, clear the previous range. I''m having a hard time finding an event to use to capture this situation. Also note they could be selecting via a drag or shift/ctrl-click. Any idea what event(s) to use?
