<h5 id="GrapeCity_ActiveReports_Viewer_Win_Viewer_AutoExecuteWithDefaultParams_remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>When set to <code>false</code> and all report parameters have default values, the viewer opens the parameters panel on load
without starting rendering. The report renders only after the user clicks &quot;Preview&quot; in the parameters panel.
This setting has no effect on reports that have no parameters or reports where at least one parameter has no default value —
in both cases the behavior is unchanged.
The default value is <code>true</code>, which preserves the existing auto-execute behavior.</p>
