비활성 상태 일 때 DataGrid의 선택된 행 색상

비활성 상태 일 때 DataGrid의 선택된 행 색상

---

DataGrid가 포커스를 잃었을 때 선택한 행의 색상을 변경하도록 WPF DataGrid의 스타일을 어떻게 지정할 수 있습니까?

오랜 시간 동안 검색 한 후, 앞서 게시 한 Got / LostFocus 접근 방식보다 더 깔끔한 놀랍도록 간단한 방법을 찾았습니다.

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

이렇게하면 비활성 배경색이 DarkGray로 설정되고 활성 배경색은 기본값으로 유지되지만 SystemColors.HighlightBrushKey를 사용하여이를 변경할 수도 있습니다.

비활성 선택을위한 포 그라운드 리소스 키는 SystemColors.InactiveSelectionHighlightTextBrushKey입니다.

4.0에서 작동하는 완벽한 솔루션입니다. 이것은 CellStyle에 있습니다.

<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>

다음과 같이하십시오.

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

이 답변 중 어느 것도 내가 찾고 있던 것을 제공하지 못했습니다. Steve Streeting의 최고 평점은 변경하고 싶지 않은 데이터 그리드의 다른 섹션을 변경했으며 다른 답변은 비활성 색상 변경을 제공하지 않았지만 행만 올바르게 타겟팅했습니다. 그래서 여기 에 그리드의 다른 위치가 아닌 행 에서만 비활성 색상 을 변경하는 답변의 혼합 이 있습니다.

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

.Net Framework 4.0 (또는 InactiveSelection ... 브러시 키를 사용하지 않으려는 경우) : DataGridRow 스타일 / 컨트롤 템플릿을 만들고 다음 트리거를 추가합니다.

<ControlTemplate.Triggers>
    <Trigger  Property="IsSelected" Value="true">
        <Setter Property="Background" Value="{DynamicResource SelectionBrush}" />
    </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 InactiveSelectionBrush}" />
        </MultiDataTrigger.Setters>
    </MultiDataTrigger>
</ControlTemplate.Triggers>

.net Framework 4.0의 경우

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

최신 답변 :

This works in .Net 4.0, and you don't have to hardcode the color:

<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>

You should define section "DataGrid.CellStyle" inside your DataGrid like this:

    <DataGrid>
        <DataGrid.CellStyle>
            <Style TargetType="DataGridCell">
                <Style.Triggers>
                    <Trigger Property="IsSelected" Value="True">
                        <Setter Property="Background" Value="LightBlue"/>
                    </Trigger>
                </Style.Triggers>
            </Style>
        </DataGrid.CellStyle>
    </DataGrid>

Find an answer by myself.

Add to DataGrid's resources the brush, which can change its 'Color' property from code behind, and reference HighlightBrushKey to it:

<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>

Then add DataGrids event handlers to manually change the color:

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;
}

I added this to my ResourceDictionary so that it applies to all data grids in my program.

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