How to Change UltraWebGrid Cell Value from a Menu Control on the same page

I have an ultrawebgrid with a "status" column.  I want the user to be able to change the value of the Status cell in the most recently active row by clicking a menu option like "Completed" or "Cancelled."  The problem is that once I click on the menu the UltraGrid is no longer active and I can't figure out how to determine the index value of the most recently active row.  Once I have the index value I hope to do something like Me.UltraGrid1.Rows(index value).Cells(3).Value = "Completed."  I am also aware that I may need to store the activerow value somewhere else and access it from the menu code.

Please help me!!
