Question

我正在使用WPF Datagrid，我想有条件地删除，就像我的下面的代码适用于斜体，我想用删除线替换斜体。 Property =“TextBlock.TextDecorations”Value =“删除线”没有帮助。我在datagrid中有5个textcolumns和1个templatecolumn。

    <Style x:Key="abcRowStyle" TargetType="{x:Type DataGridRow}">
        <Style.Triggers>
            <DataTrigger Binding="{Binding IsActive}" Value="false" >
                <Setter Property="FontStyle" Value="Italic" />
            </DataTrigger>
        </Style.Triggers>
    </Style>

Answer 1

我在文本块上使用了以下内容然后应用于单个文本列，这是有效的。并有条件地在datagridrow上应用opacity = .5。看起来不错！

   <Style x:Key="RightAlignStyle" TargetType="{x:Type TextBlock}">
        <Setter Property="TextAlignment" Value="Right" />
        <Setter Property="Padding" Value="5,0"/>
        <Style.Triggers>
            <DataTrigger Binding="{Binding IsActive}" Value="false">
                <Setter Property="TextDecorations" Value="Strikethrough" />
            </DataTrigger>
        </Style.Triggers>
    </Style>
    <Style x:Key="DefaultStyle" TargetType="{x:Type TextBlock}">
        <Style.Triggers>
            <DataTrigger Binding="{Binding IsActive}" Value="false">
                <Setter Property="TextDecorations" Value="Strikethrough" />
            </DataTrigger>
        </Style.Triggers>
    </Style>
