It will Help u

 {
     #region header with no record
     ds_login.Tables[0].Rows.Add(ds_login.Tables[0].NewRow());
     GridView1.DataSource = ds_login;

     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";
                }
