Indeed, the CurrentRowChanged
event could do the work as well as the CellBeginEdit
(we've tested it and found no irregularities). If you need any further assistance with this, let us know.
In response to your second question: currently, it is not possible to type text freely within the text are of the DropDown list. It only allows you to select the value from the items in the drop-down window. We're working on implementing this feature - it will be introduced in the next major release (Q3 2007) at the latest.
Thank you for your time.
