Change row order and order value

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();
