Hi regina,
I am glad to hear that you have found a way solve your issue. I just want to mention that
RowIndex comes from the event arguments in the
CellDoubleClick event, just like Emanuel mentioned. Note that the discussed version of RadControls for WinForms here is Q3 2010.
Should you have any other questions, do not hesitate to contact us.
All the best,
Stefan
