I'm using .NET 3.5, so I don't have all of the nice touch screen goodness. I created my own touch screen ScrollViewer
that works alright. I'm wanting to incorporate that into the DocumentViewer
template, but its not working. Here is my variation of the template:
<Style 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"
Visibility="Collapsed">
<Button Command="ApplicationCommands.Print"
CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
Content="Print" />
<Button Command="ApplicationCommands.Copy"
CommandTarget="{Binding RelativeSource={RelativeSource TemplatedParent}}"
Content="Copy" />
<Separator />
<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>
<custom:TouchScrollViewer x:Name="PART_ContentHost"
Grid.Row="1">
<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>
</custom:TouchScrollViewer>
<ContentControl Grid.Row="2" x:Name="PART_FindToolBarHost" Visibility="Collapsed"/>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
This doesn't work, because the act of moving your finger over the viewer just selects text. The template is requires a ScrollViewer
(or derivative thereof) with the name "PART_ContentHost". Is there a way to lock a ScrollViewer
to stretch to the extent of its contents. I could then wrap my own TouchScrollViewer
around the entire DocumentViewer
. Or is there a way to make the document viewer hit-test invisible (i.e IsHItTestVisible = false
). Thanks in advance.
