Addhandler problem when refreshing the grid

Hi all,
I used this example http://www.xceedsoft.com/Forums/ShowPost.aspx?PostID=1714 to capture a right-click on a cell. Now I have a problem when I need to refresh the grid: As there might be new rows I need to subscribe to them. Currently I subscribe to ALL cells again so after refreshing the grid 3 times the event is fired 4 times 🙁
What is the best way to prevent this? Is there a property to find out whether a cell is already subscribed to a handler? Do I need to keep internal records storing which cells are already subscribed? Or should I just frist remove and then add? I would like to have the <b>fastest</b> solution for the user. Maybe someone could post an example? I guess I’m not the first with this problem… 😉

Don’t subscribe to all the cells each time.
Catch the <b>AddingDataRow</b>-event of the gridcontrol, and in that eventhandler subscribe to the cells in the newly added datarow.
