<div class="markdown level0 remarks"><p>You can use this event to cancel rendering a report when the source recordset is empty.</p>
<p>If you don't cancel the report, it will be rendered as an unbound report (a self-contained report 
with no underlying data).</p>
</div>
<h5 id="C1_Report_FlexReport_NoData_examples"><strong>Examples</strong></h5>
<p>The code below cancels a report when it has no data:</p>

{
    _c1r.Cancel = true;
}</code></pre>
