There isn't a direct equivalent. You actually have to do some work to get a
match. In the GridView, you have the RowCommand which is based on the
GridViewCommandEventArgs. The one big difference is that the event handler
is not aware of the actual row that it was triggered from, so you need to
use the CommandArgument property as a means to capture your RowIndex value,
generally by using the RowCreated event.
Note that there are several events that could be used for generic row
handling. Look at the MSDN SDK documentation for more information.
