它会帮助你 It will Help u if (ds_login.Tables[0].Rows.Count == 0) { #region header with no record ds_login.Tables[0].Rows.Add(ds_login.Tables[0].NewRow()); GridView1.DataSource = ds_login; GridView1.DataBind(); int columncount = GridView1.Rows[0].Cells.Count; GridView1.Rows[0].Cells.Clear(); GridView1.Rows[0].Cells.Add(new TableCell()); GridView1.Rows[0].Cells[0].ColumnSpan = columncount; GridView1.Rows[0].Cells[0].Text = "No Records Found"; #endregion } else { GridView1.DataSource = ds_login; GridView1.DataBind(); }

你可以通过 you can do it by if (dt.Rows.Count > 0) { grid1.DataSource = dt; grid1.DataBind(); } else { dt.Rows.Add(dt.NewRow()); grid1.DataSource = dt; grid1.DataBind(); int totalcolums = grid1.Rows[0].Cells.Count; grid1.Rows[0].Cells.Clear(); grid1.Rows[0].Cells.Add(new TableCell()); grid1.Rows[0].Cells[0].ColumnSpan = totalcolums; grid1.Rows[0].Cells[0].Text = "No Data Found"; }
