- 3 minutes to read
The following code examples show how to customize or hide the context menu.
Customize the Popup Menu
You can customize pop-up menu in code or in XAML.
XAML
Use the CommandProvider.Actions (for Bar command UI) or CommandProvider.RibbonActions (for Ribbon command UI) property to access the collection of actions. Use RemoveAction, UpdateAction or InsertAction to customize DefaultPdfBarManagerItemNames items.
This example shows how to remove items and add the Save As… item to the pop-up menu:
<dxpdf:PdfViewerControl x:Name="pdfViewer"
ShowStartScreen="True"
CommandBarStyle="Ribbon">
<dxpdf:PdfViewerControl.CommandProvider>
<dxpdf:PdfCommandProvider>
<dxpdf:PdfCommandProvider.RibbonActions>
<!--Remove Hand Tool and Select All items-->
<dxb:RemoveAction ElementName="{x:Static dxpdf:DefaultPdfBarManagerItemNames.HandTool}"/>
<dxb:RemoveAction ElementName="{x:Static dxpdf:DefaultPdfBarManagerItemNames.SelectAll}"/>
<!--Add new Save As item-->
<dxb:InsertAction ContainerName="{x:Static dxpdf:DefaultPdfBarManagerItemNames.ContextMenu}">
<dxb:InsertAction.Element>
<dxb:BarButtonItem Content="Save" LargeGlyph="{dx:DXImage Image=SaveAs_16x16.png}"
Command="{Binding ElementName=pdfViewer, Path=SaveAsCommand}"/>
</dxb:InsertAction.Element>
</dxb:InsertAction>
</dxpdf:PdfCommandProvider.RibbonActions>
</dxpdf:PdfCommandProvider>
</dxpdf:PdfViewerControl.CommandProvider>
</dxpdf:PdfViewerControl>
