推荐答案

您好，这里考虑dtCustomer是包含您的数据的DataTable.
代码在下面

Hi, here consider dtCustomer is DataTable which contains your Data.
code is below

if (dtCustomer != null)
        {
            if (dtCustomer.Rows.Count > 0)
            {
                GridView1.DataSource = dtCustomer;
                GridView1.DataBind();
            }
            else
            {
                dtCustomer.Rows.Add(dtCustomer.NewRow());
                GridView1.DataSource = dtCustomer;
                GridView1.DataBind();
                int TotalColumns = GridView1.Rows[0].Cells.Count;
                GridView1.Rows[0].Cells.Clear();
                GridView1.Rows[0].Cells.Add(new TableCell());
                GridView1.Rows[0].Cells[0].ColumnSpan = TotalColumns;
                GridView1.Rows[0].Cells[0].Text = "No Data";
            }
        }
else
{
  //Here if you want, you can call the inner else condition code here
}
