更改 WPF ListViewItem 的选择颜色 [英] Change selection-color of WPF ListViewItem
问题描述
我有一个包含一些 ListViewItems 的 ListView.默认情况下,选择项目会使它们的背景变成深蓝色.我想应用一种样式,以便选择项目不会改变其外观.
I have a ListView containing some ListViewItems. By default, selecting items makes their background to some deep blue. I would like to apply a style such that selecting an item does not change its look.
在我的 xaml 中,我已经做到了:
In my xaml I already achieved this:
<Style TargetType="ListViewItem">
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
</Style.Resources>
</Style>
不幸的是,这并不能解决问题.它只是简单地使选择变为白色而不是蓝色.
Unfortunately, this does not do the trick. It just simply makes the selection white instead of blue.
有人有想法吗?
最好的祝福,克里斯蒂安

示例代码:
<Window.Resources>
<Style TargetType="ListViewItem">
<Style.Resources>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}" Color="Black"/>
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Transparent"/>
</Style.Resources>
</Style>
</Window.Resources>
<ListView x:Name="lvTestRun" ItemsSource="{Binding Path=TestRunData}" Margin="177,26,8,53.277" SelectionMode="Multiple">
<ListView.View>
<GridView>
<GridViewColumn Header="Status"/>
<GridViewColumn Header="Duration"/>
<GridViewColumn Header="Start Time"/>
<GridViewColumn Header="End Time"/>
</GridView>
</ListView.View>
</ListView>
为了重现这一点,您可能需要将单个 ListViewItem 的背景颜色设置为绿色或红色之类的颜色.
In order to reproduce this, you may have to set the background color of a single ListViewItem to something like green or red.
推荐答案
我不确定我是否理解你所说的白色而不是蓝色是什么意思.当一个 ListViewItem 被选中时,前景和背景会被触发器改变.要更改 ListViewItem 的前景,您可以使用它
I'm not sure I understand what you mean by white instead of blue. When a ListViewItem is selected the foreground and background is changed by a trigger. To change the foreground of a ListViewItem you can use this
<ListView ...>
<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}">
<Style.Resources>
<!-- Foreground for Selected ListViewItem -->
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightTextBrushKey}"
Color="Black"/>
<!-- Background for Selected ListViewItem -->
<SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}"
Color="Transparent"/>
</Style.Resources>
</Style>
</ListView.ItemContainerStyle>
...
</ListView>
更新
试试这个来重新模板.我删除了选定的所有触发器
Try this for re-templating. I removed all triggers for selected
<ListView ...>
<ListView.ItemContainerStyle>
<Style TargetType="{x:Type ListViewItem}">
<Style.Resources>
<LinearGradientBrush x:Key="ListItemHoverFill" EndPoint="0,1" StartPoint="0,0">
<GradientStop Color="#FFF1FBFF" Offset="0"/>
<GradientStop Color="#FFD5F1FE" Offset="1"/>
</LinearGradientBrush>
</Style.Resources>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ListViewItem}">
<Border CornerRadius="2" SnapsToDevicePixels="True"
BorderThickness="{TemplateBinding BorderThickness}"
BorderBrush="{TemplateBinding BorderBrush}"
Background="{TemplateBinding Background}">
<Border Name="InnerBorder" CornerRadius="1" BorderThickness="1">
<Grid>
<Grid.RowDefinitions>
<RowDefinition MaxHeight="11" />
<RowDefinition />
</Grid.RowDefinitions>
<Rectangle Name="UpperHighlight" Visibility="Collapsed" Fill="#75FFFFFF" />
<GridViewRowPresenter Grid.RowSpan="2"
VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
</Grid>
</Border>
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Background" Value="{StaticResource ListItemHoverFill}" />
<Setter Property="BorderBrush" Value="#FFCCF0FF" />
<Setter TargetName="UpperHighlight" Property="Visibility" Value="Visible" />
</Trigger>
<!--<Trigger Property="IsSelected" Value="True">
<Setter Property="Background" Value="{StaticResource ListItemSelectedFill}" />
<Setter Property="BorderBrush" Value="#FF98DDFB" />
<Setter TargetName="InnerBorder" Property="BorderBrush" Value="#80FFFFFF" />
<Setter TargetName="UpperHighlight" Property="Visibility" Value="Visible" />
<Setter TargetName="UpperHighlight" Property="Fill" Value="#40FFFFFF" />
</Trigger>-->
<!--<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsSelected" Value="True" />
<Condition Property="Selector.IsSelectionActive" Value="False" />
</MultiTrigger.Conditions>
<Setter Property="Background" Value="{StaticResource ListItemSelectedInactiveFill}" />
<Setter Property="BorderBrush" Value="#FFCFCFCF" />
</MultiTrigger>-->
<!--<MultiTrigger>
<MultiTrigger.Conditions>
<Condition Property="IsSelected" Value="True" />
<Condition Property="IsMouseOver" Value="True" />
</MultiTrigger.Conditions>
<Setter Property="Background" Value="{StaticResource ListItemSelectedHoverFill}" />
<Setter Property="BorderBrush" Value="#FF98DDFB" />
</MultiTrigger>-->
<Trigger Property="IsEnabled" Value="False">
<Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</ListView.ItemContainerStyle>
</ListView>
