1. What is the difference between RowCreated and RowDataBound ?

The Bound Cell Data is not available in RowCreated event.

Otherwise there all the things which can be done in RowDataBound
can also be done in RowCreated ( things which do not involve bound data).

Other difference is RowCreated is automatically called in
Postback and Nonpostback scenarios. RowDataBound is called when a
call to DataBind is given.


2. What is RowCommand ?
This is an event fired when command button is clicked on Gridview.
The command button can be one of the system types (delete, edit, update,..)
or custom command type.
