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
