我想使用System.Windows.Controls.DocumentViewer来查看FixedDocument我使用TallComponents.PDF.Rasterizer. 这是可行的，但是，我想禁用或删除DocumentViewer控件显示的一些工具栏按钮。我正在使用此处的模板示例。

<Style x:Key="{x:Type DocumentViewer}"
       TargetType="{x:Type DocumentViewer}">
  <Setter Property="Foreground"
      Value="{DynamicResource {x:Static SystemColors.WindowTextBrushKey}}" />
  <Setter Property="Background"
      Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}" />
  <Setter Property="FocusVisualStyle"
          Value="{x:Null}" />
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type DocumentViewer}">
        <Border BorderThickness="{TemplateBinding BorderThickness}"
                BorderBrush="{TemplateBinding BorderBrush}"
                Focusable="False">
          <Grid KeyboardNavigation.TabNavigation="Local">
            <Grid.Background>
              <SolidColorBrush Color="{DynamicResource ControlLightColor}" />
            </Grid.Background>
            <Grid.RowDefinitions>
              <RowDefinition Height="Auto" />
              <RowDefinition Height="*" />
              <RowDefinition Height="Auto" />
            </Grid.RowDefinitions>
            <ToolBar ToolBarTray.IsLocked="True"
                     KeyboardNavigation.TabNavigation="Continue">
              <Button Command="NavigationCommands.IncreaseZoom"
  CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
                      Content="Zoom In" />
              <Button Command="NavigationCommands.DecreaseZoom"
  CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
                      Content="Zoom Out" />
              <Separator />
              <!--
              <Button Command="NavigationCommands.Zoom"
  CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
                      CommandParameter="100.0"
                      Content="Actual Size" />
              -->
              <Button Command="DocumentViewer.FitToWidthCommand"
  CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
                      Content="Fit to Width" />
              <Button Command="DocumentViewer.FitToMaxPagesAcrossCommand"
  CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
                      CommandParameter="1"
                      Content="Whole Page" />
              <Button Command="DocumentViewer.FitToMaxPagesAcrossCommand"
  CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
                      CommandParameter="2"
                      Content="Two Pages" />
            </ToolBar>
            <ScrollViewer Grid.Row="1"
                          CanContentScroll="true"
                          HorizontalScrollBarVisibility="Auto"
                          x:Name="PART_ContentHost"
                          IsTabStop="true">
              <ScrollViewer.Background>
                <LinearGradientBrush EndPoint="0.5,1"
                                     StartPoint="0.5,0">
                  <GradientStop Color="{DynamicResource ControlLightColor}"
                                Offset="0" />
                  <GradientStop Color="{DynamicResource ControlMediumColor}"
                                Offset="1" />
                </LinearGradientBrush>
              </ScrollViewer.Background>
            </ScrollViewer>
            <ContentControl Grid.Row="2"
                            x:Name="PART_FindToolBarHost"/>
          </Grid>
        </Border>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

这与链接的示例非常相似，但我删除了打印和复制命令按钮。我不希望用户能够使用这些按钮。

我还必须注释掉该Zoom命令，IDE 抱怨这不是一个有效的命令，该问题的答案的奖金投票。

This all works but after templating I no longer get the images on the tool bar buttons, just the text I specified in Content. So my question is, "Can I bind to use content from the controls nested in the templated parent?"

Here's what I got when I used Blend to extract and edit the template for the DocumentViewer. I commented out the two buttons you mentions.

As far as the Zoom commands, it might have complained about invalid commands because you were missing a namespace import for System.Windows.Documents.

Xaml:
