If an ultrawingrid cell is enabled as a drop down list, what method would capture the event if any item from that drop down list is selected?
You can use the CellChange event to trap when any cell is changed. Note, however, that you must use the Text property of the cell to determine the new (edited) value of the cell. You cannot use the Value property because Value reads from the underlying data source, which will not be updated until you leave the cell (or possibly the row, depending on the UpdateMode property).
