c# - WPF ListView - 资源和 ItemContainerStyle

Question

只是一个简短的问题。我可以同时使用 ListView.Resources 和 ListView.ItemContainerStyle 吗？如果我一起使用，似乎只有其中一个在工作..

<ListView.Resources>
    <Style TargetType="{x:Type ListViewItem}">
        <Style.Triggers>
            <DataTrigger Binding="{Binding PAMStatus}" Value="ACTIVE">
                <Setter Property="Background" Value="DimGray" />
            </DataTrigger>

        </Style.Triggers>

<ListView.ItemContainerStyle>
    <Style TargetType="ListViewItem">
        <Setter Property="HorizontalContentAlignment" Value="Stretch" />
    </Style>
</ListView.ItemContainerStyle>

Answer 1

It seems only one of them is working if i use together..

是的，ListViewItem(s) 只能应用一种样式。

但是您可以通过创建基于原始样式的新样式来“扩展”样式:

<ListView ...>
    <ListView.Resources>
        <Style x:Key="style" TargetType="{x:Type ListViewItem}">
            <Style.Triggers>
                <DataTrigger Binding="{Binding PAMStatus}" Value="ACTIVE">
                    <Setter Property="Background" Value="DimGray" />
                </DataTrigger>

            </Style.Triggers>
        </Style>
    </ListView.Resources>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem" BasedOn="{StaticResource style}">
            <Setter Property="HorizontalContentAlignment" Value="Stretch" />
        </Style>
    </ListView.ItemContainerStyle>
</ListView>
