Guys, the problem here is that I need to delete the old row and insert a new row in Gridview in EDIT mode. So help me with some code which would Insert/Update new values given in Edit mode and also clearing previous stored/bind value.
When I am updating, the Gridview holds the bind value in it thus not letting Update operation to cause effects.
