Solution 1

Are You binding your gridview to arraylist.
if yes then

C#

else
{
arr = new ArrayList();
Session["mycart"] = arr;
}

when you store arr to session, before that you have to initialize arraylist arr

Solution 2

SQL

check the index of rows and cells. check if there is any value or not.
try 0 instead of 1 in 'rows[1]'.
like:-
GridView1.Rows[0].Cells[1].Text;
