DataGrid在不活动时选择的行颜色

Question

当DataGrid失去焦点时,如何设置WPF DataGrid的样式以更改所选行的颜色？

Answer 1

After ages of searching, I found a surprisingly simple way to do this that's cleaner than the Got/LostFocus approach posted earlier:

<DataGrid.Resources>
    <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="DarkGray"/>
</DataGrid.Resources>

This just sets the inactive background colour to DarkGray, leaving the active background colour to the default, but you can change that too using the SystemColors.HighlightBrushKey too of course.

The foreground resource key for inactive selections is SystemColors.InactiveSelectionHighlightTextBrushKey.

适用于4.0的完整解决方案.请注意,这在CellStyle上.

<DataGrid.CellStyle>
    <!--Override Highlighting so that its easy to see what is selected even when the control is not focused-->
    <Style TargetType="{x:Type DataGridCell}">
        <Style.Triggers>
            <Trigger  Property="IsSelected" Value="true">
                <Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" />
                <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}" />
                <Setter Property="BorderBrush" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" />
            </Trigger>
            <MultiDataTrigger>
                <MultiDataTrigger.Conditions>
                    <Condition Binding="{Binding RelativeSource={RelativeSource Self}, Path=IsSelected}" Value="True" />
                    <Condition Binding="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=DataGrid}, Path=IsKeyboardFocusWithin}" Value="False" />
                </MultiDataTrigger.Conditions>
                <MultiDataTrigger.Setters>
                    <Setter Property="Background" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" />
                    <Setter Property="Foreground" Value="{DynamicResource {x:Static SystemColors.HighlightTextBrushKey}}" />
                    <Setter Property="BorderBrush" Value="{DynamicResource {x:Static SystemColors.HighlightBrushKey}}" />
                </MultiDataTrigger.Setters>
            </MultiDataTrigger>
        </Style.Triggers>
    </Style>
</DataGrid.CellStyle>

像这样做:

<DataGrid ...>
    <DataGrid.Resources> 
        <Style TargetType="DataGridRow"> 
            <Style.Resources> 
                <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Red"/>                                  
            </Style.Resources> 
        </Style> 
   </DataGrid.Resources> 
...

Answer 4

这些答案都没有给我我想要的。Steve Streeting 评分最高的更改了我不想更改的数据网格的其他部分，其他答案并未提供非活动颜色更改，而是仅正确定位该行。所以这是他们的答案的混合，改变了非活动颜色，只在行上，而不是在网格的其他地方。

<DataGrid.Resources>
    <Style TargetType="DataGridRow">
        <Style.Resources>
            <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" Color="DarkGray"/>
        </Style.Resources>
    </Style>
</DataGrid.Resources>

Answer 5

迟到的回答：

这适用于.Net 4.0，您不必对颜色进行硬编码：

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

Answer 6

自己找答案吧。

将画笔添加到 DataGrid 的资源中，该画笔可以从后面的代码更改其“Color”属性，并引用highlightbrushkey：

<DataGrid.Resources>
    <SolidColorBrush x:Key="SelectionColorKey" Color="DarkGray"/>
    <Style TargetType="DataGridRow">
        <Style.Resources>
            <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="{Binding Source={StaticResource SelectionColorKey}, Path=Color}"/>
        </Style.Resources>
    </Style>
</DataGrid.Resources>

然后添加 DataGrids 事件处理程序以手动更改颜色：

private void DataGrid1_LostFocus(object sender, RoutedEventArgs e)
{
    ((SolidColorBrush)DataGrid1.Resources["SelectionColorKey"]).Color = Colors.DarkGray;
}

private void DataGrid1_GotFocus(object sender, RoutedEventArgs e)
{
    ((SolidColorBrush)DataGrid1.Resources["SelectionColorKey"]).Color = SystemColors.HighlightColor;
}

private void DataGrid1_LostKeyboardFocus(object sender, KeyboardFocusChangedEventArgs e)
{
    ((SolidColorBrush)DataGrid1.Resources["SelectionColorKey"]).Color = Colors.DarkGray;
}
