在DataGrid的Selected Row中设置元素的前景颜色

Question

我有一个DataGridTemplateColumn定义如下。如果选择了行，我需要将两个文本块的Foreground属性更改为White

<DataGrid.Columns>
<DataGridTemplateColumn  Header="User" Width="240" >
    <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
            <StackPanel>
                <TextBlock Margin="10,3,0,0" Foreground="#1c72c7" >
                        <Run Text="{Binding FullName, Mode=OneWay}" />
                </TextBlock>
                <Label Padding="0,0,0,0"  Margin="0,0,0,3">
                    <TextBlock Foreground="#1c72c7"  Margin="10,0,0,0" TextDecorations="Underline" Text="{Binding DisplayName}" />
                </Label>
            </StackPanel>
        </DataTemplate>
    </DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

我已经定义了RowStyle以更改行的背景颜色，如下所示

 <DataGrid.RowStyle>
<Style TargetType="{x:Type DataGridRow}">
    <Style.Resources>
        <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="{x:Static SystemColors.HighlightColor}" />
    </Style.Resources>

</Style>

您应该为每个人Style修改TextBlock，并按照您的喜好添加行为：

 <Style x:Key="FirstTextBlockStyle" TargetType="TextBlock">
    <Setter Property="Foreground" Value="Black" />
    <Style.Triggers>
       <DataTrigger Binding="{Binding IsSelected, 
             RelativeSource= {RelativeSource 
                                AncestorType={x:Type DataGridRow}}}" 
             Value="True">
           <Setter Property="Foreground" Value="White" />
        </DataTrigger>
     </Style.Triggers>
 </Style>
