ListViewItem 覆盖默认样式中断网格视图

我想知道是否有人遇到过这种情况。基本上我想做的是覆盖默认的列表视图项以自定义所选的背景/前景。我一切顺利。问题是，我注意到在我实现了网格视图的列表视图上，列被破坏了。我不确定会发生什么来打破这个。我覆盖默认样式的方法是使用混合通过编辑模板副本来获取完整样式。根据需要修改它。应用了它。这几乎就是它看起来的样子。有什么想法吗？

<Style TargetType="{x:Type ListViewItem}">
    <Setter Property="Background" Value="Transparent" />
    <Setter Property="HorizontalContentAlignment" Value="{Binding HorizontalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}" />
    <Setter Property="VerticalContentAlignment" Value="{Binding VerticalContentAlignment, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}" />
    <Setter Property="Padding" Value="2,0,0,0" />
    <Setter Property="Template">
    <Setter.Value>
    <ControlTemplate TargetType="{x:Type ListViewItem}">
        <Border x:Name="Bd"
            Background="{TemplateBinding Background}"
            BorderBrush="{TemplateBinding BorderBrush}"
            BorderThickness="{TemplateBinding BorderThickness}"
            Padding="{TemplateBinding Padding}"
            SnapsToDevicePixels="true">
            <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}"
                VerticalAlignment="{TemplateBinding VerticalContentAlignment}"
                SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" />
        </Border>
    <ControlTemplate.Triggers>
        <Trigger Property="IsSelected" Value="true">
            <Setter TargetName="Bd" Property="BorderBrush" Value="{DynamicResource CustomBorderBrush}" />
            <Setter TargetName="Bd" Property="Background" Value="{DynamicResource CustomBackgroundBrush}" />
            <Setter Property="Foreground" Value="{DynamicResource CustomForegroundBrush}" />
        </Trigger>
    <MultiTrigger>
        <MultiTrigger.Conditions>
            <Condition Property="IsSelected" Value="true" />
            <Condition Property="Selector.IsSelectionActive" Value="false" />
    </MultiTrigger.Conditions>
    <Setter TargetName="Bd" Property="Background" Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}" />
    <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.ControlTextBrushKey}}" />

    <Trigger Property="IsEnabled" Value="false">
        <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.GrayTextBrushKey}}" />
    </Trigger>
    </ControlTemplate.Triggers>
    </ControlTemplate>
    </Setter.Value>
    </Setter>
</Style>

<ListView Grid.Row="0" Grid.Column="0" Margin="15,15,0,0" Name="lstResources" SelectionChanged="lstResources_SelectionChanged">
        <ListView.View>
            <GridView>
                <GridView.Columns>
                    <GridViewColumn x:Name="column1"  Header="column1" Width="100" CellTemplate="{StaticResource column1template}"/>
                    <GridViewColumn x:Name="column2" Header="column2" Width="100" CellTemplate="{StaticResource column2template}" />
                    <GridViewColumn x:Name="column3" Header="column3" Width="200" CellTemplate="{StaticResource column3template}" WPFUtility:GridViewColumnResize.Width="*"/>
                </GridView.Columns>
            </GridView>
        </ListView.View>
</ListView>

<DataTemplate x:Key="column1template">
        <DockPanel>
            <TextBlock HorizontalAlignment="stretch" TextTrimming="CharacterEllipsis" >
            <TextBlock.Text>
                <Binding Path="mycontent"/>
            </TextBlock.Text>
            </TextBlock>
        </DockPanel>
    </DataTemplate>

我检查了控制模板ListViews在这两种情况下，得出的结论是样式不适用于GridViews因为他们需要一个GridViewRowPresenter http://msdn.microsoft.com/en-us/library/system.windows.controls.gridviewrowpresenter.aspx正确布局行数据，而不是ContentPresenter.

当然，如果你这样做，你会发现你的正常情况ListViews哪个不使用GridViews不再正确格式化，因为它们需要ContentPresenter.

我并不完全确定解决这个问题的最好方法，但偶然发现了这篇博客文章：http://www.steelyeyedview.com/2010/03/contentpresenter-gridviewrowpresenter.html http://www.steelyeyedview.com/2010/03/contentpresenter-gridviewrowpresenter.html

我将在这里重复一下要点，以防它被删除：

他的解决方案是一个巧妙的小技巧，并且似乎有效。它利用了两位演示者，ContentPresenter默认隐藏（Visibility="Collapsed"），并使用触发器来使ContentPresenter可见，如果GridViewRowPresenter没有内容。自从GridViewRowPresenter没有内容，无论如何也不会显示任何内容。

调整你的Style要包含他的修复，您将得到类似的内容（为了获得焦点而删除了一些代码）：

<Style TargetType="{x:Type ListViewItem}">
    <!-- Your Code -->
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ListViewItem}">
                <Border x:Name="Bd"
                     Background="{TemplateBinding Background}"
                     BorderBrush="{TemplateBinding BorderBrush}"
                     BorderThickness="{TemplateBinding BorderThickness}"
                     Padding="{TemplateBinding Padding}"
                     SnapsToDevicePixels="true">
                    <Grid>
