所以,我在XAML中写了ListBox
:
<ListBox Margin="0" x:Name="ListBox_Main" Grid.Row="1" VerticalAlignment="Top" FontSize="24" SelectionChanged="ListBox_Main_SelectionChanged" Foreground="Black">
<ListBoxItem Content="Item 1" Background="#19000000" />
<ListBoxItem Content="Item 2" Background="#19000000" />
<ListBoxItem Content="Item 3" Background="#19000000" />
<ListBoxItem Content="Item 4" Background="#19000000"/>
<ListBoxItem Content="Item 5" Background="#19000000"/>
</ListBox>
我可以更改背景,前景和列表框项目文本的颜色,但是在选择任何项目时没有选项可以更改颜色,默认情况下它是蓝色的:
我们可以改变那种蓝色吗?
答案 0 :(得分:0)
您需要根据您的要求更改ListBoxItem
的默认样式模板。 MSDN Reference
<Style TargetType="ListBoxItem">
<Setter Property="Padding" Value="3" />
<Setter Property="HorizontalContentAlignment" Value="Left" />
<Setter Property="VerticalContentAlignment" Value="Top" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="BorderThickness" Value="1"/>
<Setter Property="TabNavigation" Value="Local" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListBoxItem">
<Grid Background="{TemplateBinding Background}">
<vsm:VisualStateManager.VisualStateGroups>
<vsm:VisualStateGroup x:Name="CommonStates">
<vsm:VisualState x:Name="Normal" />
<vsm:VisualState x:Name="MouseOver">
<Storyboard>
<DoubleAnimation Storyboard.TargetName="fillColor" Storyboard.TargetProperty="Opacity" Duration="0" To=".35"/>
</Storyboard>
</vsm:VisualState>
<vsm:VisualState x:Name="Disabled">
<Storyboard>
<DoubleAnimation Storyboard.TargetName="contentPresenter" Storyboard.TargetProperty="Opacity" Duration="0" To=".55" />
