解説

You can use this event to cancel rendering a report when the source recordset is empty.

If you don't cancel the report, it will be rendered as an unbound report (a self-contained report with no underlying data).

使用例

The code below cancels a report when it has no data:

private void c1r_NoData(object sender, EventArgs e)
{
    _c1r.Cancel = true;
}
