How to Store SelectedRow.Cell[0] value in a session when CommandField is “Select” in a GridView. ? What the changes i will do in my code so that when a Select Command executes on my grid (By Clicking on Select Link of my grid), It will Store the NatureOfWorkID of that row in the session variable. Below is my code. Please guide me that what changes required in the below code so that when ever some one will click on Select, the natureofworkID of that row will be stored in a Session and i will bind another grid from the session variable as per my requirement.

By adding these lines, Now i am able to get Cell[0] value of the selected row in my grid. Thanks To every one for guiding me to get the solution.
