I want to use the System.Windows.Controls.DocumentViewer to view a FixedDocument I created from a PDF file using TallComponents.PDF.Rasterizer. This is working, however, I want to disable or remove some of the toolbar buttons displayed by the DocumentViewer control. I’m using the template exmaple from here.
<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>
This is very similar to the linked example but I have removed the Print and Copy command buttons. I don’t want the users to be able to use those buttons.
I also had to comment out the Zoom command, the IDE complained this was not a valid command, bonus votes for the answer to that problem.
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.
