<h5 id="C1_Report_FlexReport_StartReport_remarks"><strong>Remarks</strong></h5>
<div class="markdown level0 remarks"><p>You can use this event to provide user feedback or to make changes to the 
datasources properties.</p>
<p>For example, you may implement your own version of parameterized queries by asking the 
user to provide some information and changing the <a class="xref" href="C1.Report.DataSource.RecordSource.html#C1_Report_DataSource_RecordSource">RecordSource</a> 
property accordingly.</p>
<p>You may also use this event to assign a <a class="xref" href="https://learn.microsoft.com/dotnet/api/system.data.datatable">DataTable</a> object directly to the 
report's <a class="xref" href="C1.Report.DataSource.Recordset.html#C1_Report_DataSource_Recordset">Recordset</a> property. Applications that already have the 
report data should do this to save time by preventing <a class="xref" href="C1.Report.FlexReport.html">FlexReport</a> from loading its own copy 
of the data.</p>
