使Silverlight Datagrid单元格不可选

Question

我有一个DataGrid,我绑定到一个分页和排序的PagedCollectionView.尽管一列包含可单击的链接,但DataGrid的内容不可编辑.

我已经限制DataGrid的SelectionMode DataGridSelectionMode.Single停止多行选择,这是好的.但是,所选行还有一个选定的单元格,其颜色比所选行的其余部分略微浅,并且具有边框.

基本上我想要一个SelectedRow而不是SelectedCell(从UI/Display角度来看).

感觉它应该是设置属性的简单问题,但我觉得我可能需要编辑DataGrids模板和/或使用VisualStateManager.

我很高兴切换到DataGrid以外的其他控件,但我需要能够显示分组.

Answer 1

虽然我不确定它是否是最好的方法,但我找到了'一种'使单个细胞看起来没有被选中的方法.
编辑DataGrid的CellStyle,找到名为FocusVisual的Rectangle.这是用于指示所选单元格的Rectangle.将其Fill&Stroke设置为Transparent,我还将其StrokeThickness设置为0.不要完全删除Rectangle,因为其他东西都期望它存在.xaml看起来像这样:

    <Style x:Key="NonSelectableDataGridCellStyle" TargetType="data:DataGridCell">
        <Setter Property="Background" Value="Transparent"/>
        <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
        <Setter Property="VerticalContentAlignment" Value="Stretch"/>
        <Setter Property="IsTabStop" Value="False"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="data:DataGridCell">
                    <Grid x:Name="Root" Background="{TemplateBinding Background}">
                        <Grid.ColumnDefinitions>
                            <ColumnDefinition/>
                            <ColumnDefinition Width="Auto"/>
                        </Grid.ColumnDefinitions>
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CurrentStates">
                                <VisualState x:Name="Regular"/>
                                <VisualState x:Name="Current">
                                    <Storyboard>
                                        <DoubleAnimation Duration="0" 
                                            Storyboard.TargetName="FocusVisual" 
                                            Storyboard.TargetProperty="Opacity" To="1"/>
                                    </Storyboard>
                                </VisualState>
                            </VisualStateGroup>
                            <VisualStateGroup x:Name="ValidationStates">
                                <VisualState x:Name="Valid"/>
                                <VisualState x:Name="Invalid">
                                    <Storyboard>
                                        <DoubleAnimation Duration="0" Storyboard.TargetName="InvalidVisualElement" Storyboard.TargetProperty="Opacity" To="1"/>
                                        <ColorAnimation Duration="0" Storyboard.TargetName="FocusVisual" Storyboard.TargetProperty="(Fill).Color" To="#FFFFFFFF"/>
                                    </Storyboard>
                                </VisualState>
                            </VisualStateGroup>
                        </VisualStateManager.VisualStateGroups>
                        <Rectangle x:Name="FocusVisual" 
                            Fill="Transparent"
                            Stroke="Transparent"
                            StrokeThickness="0" 
                            HorizontalAlignment="Stretch" 
                            VerticalAlignment="Stretch" 
                            IsHitTestVisible="false" 
                            Opacity="0"
                                   />
                        <ContentPresenter HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}"/>
                        <Rectangle x:Name="InvalidVisualElement" Stroke="#FFDC000C" StrokeThickness="1" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" IsHitTestVisible="False" Opacity="0"/>
                        <Rectangle x:Name="RightGridLine" VerticalAlignment="Stretch" Width="1" Grid.Column="1"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

然后将CellStyle添加到DataGrid

<data:DataGrid x:Name="uiDataGrid" 
           CellStyle="{StaticResource NonSelectableDataGridCellStyle}"
           >
     ...
</data:DataGrid>
