Render hidden pages Leave feedback

By default, GroupDocs.Viewer does not render hidden items. To render them, set the RenderHiddenPages property of the ViewOptions class to true.

This feature is supported for the following format families:

Visio documents (for hidden pages)
PowerPoint presentations (for hidden slides)
Spreadsheets files (for hidden worksheets)

The following code snippet shows how to enable rendering of hidden items:

using GroupDocs.Viewer;
using GroupDocs.Viewer.Options;
// ...

using (Viewer viewer = new Viewer("sample.pptx"))
{
    // Create view options.
    var viewOptions = HtmlViewOptions.ForEmbeddedResources();

    // Enable rendering of hidden items.
    viewOptions.RenderHiddenPages = true;
    viewer.View(viewOptions);
}

VB.NET

Imports GroupDocs.Viewer
Imports GroupDocs.Viewer.Options
' ...

Module Program
    Sub Main(args As String())
        Using viewer As Viewer = New Viewer("sample.pptx")
            ' Create view options.
            Dim viewOptions = HtmlViewOptions.ForEmbeddedResources()
        
            ' Enable rendering of hidden items.
            viewOptions.RenderHiddenPages = True
            viewer.View(viewOptions)
        End Using
    End Sub
End Module
