<h5 id="GrapeCity_ActiveReports_Viewer_Win_Viewer_PreviewPages_remarks">Remarks</h5>
<div class="markdown level1 remarks"><p>This property is particularly useful for improving the performance of report loading and rendering in scenarios where only a subset
of the report's pages needs to be previewed initially. It is applicable when loading reports from instances of <a class="xref" href="../MESCIUS.ActiveReports/GrapeCity.ActiveReports.SectionReport.html">SectionReport</a> or <a class="xref" href="../MESCIUS.ActiveReports/GrapeCity.ActiveReports.Document.PageDocument.html">PageDocument</a>.
When a report is loaded with a specific number of preview pages set, only those pages will be available for preview in the viewer.
This can significantly reduce the time and resources required to load and display large reports.</p>

<h5 id="GrapeCity_ActiveReports_Viewer_Win_Viewer_PreviewPages_examples">Examples</h5>
<p>This example shows how to set the PreviewPages property programmatically in a WinForms application that uses the Viewer control.</p>
