Dear  please use datatable in grid view first time binding then up or down click time rearrange your datatable and set your grid view from datatable that code is DataRow selectedRow = dt.Rows[key]; DataRow newRow = dt.NewRow(); newRow.ItemArray = selectedRow.ItemArray; // copy data dt.Rows.Remove(selectedRow); dt.Rows.InsertAt(newRow key + 1 / -1); GridView1.DataSource = dt; GridView1.DataBind(); so please read my fisrt post change your application Thanks sreejesh
