[英]Edit the Style of a ScrollViewer
我為ListBox的ScrollViewer使用以下樣式,但是我不知道將其放在ListBox的xaml中的位置:
<Style x:key"Style1" TargetType="ScrollViewer">
<Setter Property="VerticalScrollBarVisibility" Value="Auto"/>
<Setter Property="HorizontalScrollBarVisibility" Value="Disabled"/>
<Setter Property="Background" Value="Transparent"/>
<Setter Property="Padding" Value="0"/>
<Setter Property="BorderThickness" Value="3"/>
<Setter Property="BorderBrush" Value="Transparent"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ScrollViewer">
<Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}">
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="ScrollStates">
<VisualStateGroup.Transitions>
<VisualTransition GeneratedDuration="00:00:00.5"/>
</VisualStateGroup.Transitions>
<VisualState x:Name="Scrolling">
<Storyboard>
<DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="VerticalScrollBar"/>
<DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="HorizontalScrollBar"/>
</Storyboard>
</VisualState>
<VisualState x:Name="NotScrolling"/>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
<Grid Margin="{TemplateBinding Padding}">
<ScrollContentPresenter x:Name="ScrollContentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}"/>
<ScrollBar x:Name="VerticalScrollBar" HorizontalAlignment="Right" Height="Auto" IsHitTestVisible="False" IsTabStop="False" Maximum="{TemplateBinding ScrollableHeight}" Minimum="0" Opacity="0" Orientation="Vertical" Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}" Value="{TemplateBinding VerticalOffset}" ViewportSize="{TemplateBinding ViewportHeight}" VerticalAlignment="Stretch" Width="5"/>
<ScrollBar x:Name="HorizontalScrollBar" HorizontalAlignment="Stretch" Height="5" IsHitTestVisible="False" IsTabStop="False" Maximum="{TemplateBinding ScrollableWidth}" Minimum="0" Opacity="0" Orientation="Horizontal" Visibility="{TemplateBinding ComputedHorizontalScrollBarVisibility}" Value="{TemplateBinding HorizontalOffset}" ViewportSize="{TemplateBinding ViewportWidth}" VerticalAlignment="Bottom" Width="Auto"/>
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
我必須在哪里將其添加到ListBox中以自定義ScrollViewer?
這是默認的列表框樣式: http : //msdn.microsoft.com/zh-cn/library/ms754242 (v=vs.110) .aspx您將注意到它具有滾動查看器,作為ControlTemplate的一部分。 您將需要在列表框控件模板中定位滾動查看器樣式,如下所示:
<ControlTemplate TargetType="ListBox">
<Border Name="Border"
BorderThickness="1"
CornerRadius="2">
<Border.Background>
<SolidColorBrush Color="{StaticResource ControlLightColor}" />
</Border.Background>
<Border.BorderBrush>
<SolidColorBrush Color="{StaticResource BorderMediumColor}" />
</Border.BorderBrush>
<ScrollViewer Style="{StaticResource Style1}" Margin="0"
Focusable="false">
<StackPanel Margin="2"
IsItemsHost="True" />
</ScrollViewer>
</Border>
