GridView绑定数据源，无记录时表头也显示的一种解决方法

public void BuildNoRecords(GridView gridView, DataSet ds)
{
try {
if (ds.Tables(0).Rows.Count == 0) {
ds.Tables(0).Rows.Add(ds.Tables(0).NewRow());
gridView.DataSource = ds;
gridView.DataBind();
int columnCount = gridView.Rows(0).Cells.Count;
gridView.Rows(0).Cells.Clear();
gridView.Rows(0).Cells.Add(new TableCell());
gridView.Rows(0).Cells(0).ColumnSpan = columnCount;
gridView.Rows(0).Cells(0).Text = "No Records Found.";
}
} catch (Exception ex) {
}
