           dt1.Tables[0].Rows[row.DataItemIndex][0] = ((TextBox)(row.Cells[1].Controls[0])).Text;
           dt1.Tables[0].Rows[row.DataItemIndex][1] = ((TextBox)(row.Cells[2].Controls[0])).Text;
           dt1.Tables[0].Rows[row.DataItemIndex][2] = ((TextBox)(row.Cells[3].Controls[0])).Text;
           dt1.Tables[0].Rows[row.DataItemIndex][3] = ((TextBox)(row.Cells[4].Controls[0])).Text;
           GridView1.EditIndex = -1;
           binddata();
       }

       if (Session["key"] != null)
       {
           Response.Write("hello");
           DataSet dt2 = (DataSet)Session["key"];
           dt2.Tables[0].Rows[row.DataItemIndex][0] = ((TextBox)(row.Cells[1].Controls[0])).Text;
           dt2.Tables[0].Rows[row.DataItemIndex][1] = ((TextBox)(row.Cells[2].Controls[0])).Text;
           dt2.Tables[0].Rows[row.DataItemIndex][2] = ((TextBox)(row.Cells[3].Controls[0])).Text;
           dt2.Tables[0].Rows[row.DataItemIndex][3] = ((TextBox)(row.Cells[4].Controls[0])).Text;
           GridView1.EditIndex = -1;
           binddata();
       }

only the first row is updated well for others i found error There is no row at position 1 in session["key"].. (the session["dt"] is working well it is an empty dataset")

Well, error simple states that Session["key"] has a dataset that has only one row in it.

You need to use DEBUGGER and see yourself what is stored in Session["key"]; and verify that it stored a dataset that has more that many rows as much you expect and have written code for. (Here 4 rows expected)

i used debugger also if i click update in second row it was showing the error in session["dt"].
dt1.Tables[0].Rows[row.DataItemIndex][0] = ((TextBox)(row.Cells[1].Controls[0])).Text;

As per error your Session["key"] has issues and contains only 1 row. After putting debugger check what is stored in session.

Earlier you said there was no issues with Session["dt"] ... now you say you do. :doh:

while updating the second row value from session["key"] it was showing the error session["dt"]. dt1.Tables[0].Rows[row.DataItemIndex][0] = ((TextBox)(row.Cells[1].Controls[0])).Text;
but while updating the session["key"] there was no error... now also i am saying that there is no issue while updating session["dt"]

Good answer, I suspect that OP expects the data to propagate to all the sessions, and would be better served by using the cache :)
