There is no implementation for responding to the Zoom command on any given WPF class. As such, you need to provide an appropriate implementation, which is shown in the example.

<object property="NavigationCommands.Zoom"/>

The following example shows how to implement code that responds to the Zoom command in conjunction with a FlowDocumentPageViewer.

<FlowDocumentPageViewer Name="flowDocumentPageViewer" MinZoom="50" MaxZoom="200">

  <!-- Zoom Context Menu-->
          Executed="navigationCommandZoom_Executed" />
      <MenuItem Header="50%" Command="NavigationCommands.Zoom" CommandParameter="50" />
      <MenuItem Header="100%" Command="NavigationCommands.Zoom" CommandParameter="100" />
      <MenuItem Header="150%" Command="NavigationCommands.Zoom" CommandParameter="150" />
      <MenuItem Header="200%" Command="NavigationCommands.Zoom" CommandParameter="200" />
