DataGridCheckBoxColumn在应用ElementStyle时失去IsReadOnly状态

问题描述

我需要垂直居中一个 DataGridCheckBoxColumn 。由于我没有在 DataGridCheckBoxColumn 中找到一个Property，所​​以我应用了一个 ElementStyle 。但是，当应用此样式时，我的 CheckBox 可以再次检查，虽然它设置为 ReadOnly 在我的 DataGrid （整个 Datagrid 是 ReadOnly ），而在code> DataGridCheckBoxColumn 本身。

I need to vertically center a DataGridCheckBoxColumn. Since I did not find a Property inside DataGridCheckBoxColumn, I applied an ElementStyle. However, when this style is applied, my CheckBox becomes checkable again, although it is set to ReadOnly in my DataGrid (the whole Datagrid is ReadOnly), and in DataGridCheckBoxColumn itself.

如何创建一个垂直居中的 CheckBox 保持其 ReadOnly 状态？这是我的代码：

How can I create a vertically centered CheckBox that keeps its ReadOnly state? Here is my code:

<DataGrid IsReadOnly="True">
    <DataGrid.Columns>
        <DataGridCheckBoxColumn Header="Test" IsReadOnly="True" Binding="{Binding MyBinding}">                        
            <DataGridCheckBoxColumn.ElementStyle>
                <Style>
                    <Setter Property="FrameworkElement.Margin" Value="0,1,0,0" />
                    <Setter Property="FrameworkElement.VerticalAlignment" Value="Center" />
                    <Setter Property="FrameworkElement.HorizontalAlignment" Value="Center" />                                
                </Style>
            </DataGridCheckBoxColumn.ElementStyle>
        </DataGridCheckBoxColumn>
    </DataGrid.Columns>
</DataGrid>

推荐答案

设置 ElementStyle 在 DataGridCheckBoxColumn 你应该包括到您的样式：

<Setter Property="FrameworkElement.IsHitTestVisible" Value="False"/>

另外如果添加 TargetType =CheckBox到 Style ，那么您不必为每个 Setter 重复 FrameworkElement code>更多：

Also if you add TargetType="CheckBox" to the Style then you don't have to repeat FrameworkElement for each Setter anymore:

<DataGridCheckBoxColumn.ElementStyle>
    <Style TargetType="CheckBox">
        <Setter Property="Margin" Value="0,1,0,0" />
        <Setter Property="VerticalAlignment" Value="Center" />
        <Setter Property="HorizontalAlignment" Value="Center" />
        <Setter Property="IsHitTestVisible" Value="False"/>
    </Style>
</DataGridCheckBoxColumn.ElementStyle>
