带有TextBlock的WPF DataGridCell模板 - 绑定？

i replace the ContentPresenter in the DataGridCell's Template with a TextBlock an now i search for the correct Binding to the content.

我用DataBlock替换DataGridCell模板中的ContentPresenter现在我搜索到内容的正确绑定。

The normal way is Text="{TemplateBinding Content} for the TextBlock - it doesn't work. Also Text="{Binding RelativeSource={RelativeSource TemplatedParent},Path=Content, Mode=TwoWay}" doesn't work correct.

正常的方法是TextBlock的Text =“{TemplateBinding Content}” - 它不起作用。还有Text =“{Binding RelativeSource = {RelativeSource TemplatedParent},Path = Content,Mode = TwoWay}”“无法正常工作。

Any other ideas?

还有其他想法吗?

Suppose you have changed the DataGridCell Template to the following

假设您已将DataGridCell模板更改为以下内容

<ControlTemplate TargetType="{x:Type DataGridCell}">
    <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
        <TextBlock Text="{Binding}"/>
        <!--<ContentPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}"/> -->
    </Border>
</ControlTemplate>

Since you removed the ContentPresenter, the DataGridCell has no way of displaying its Content. It's still there though. The DataGridCell.Content is a TextBlock containing your original Text and the TextBlock in the Template is another.

由于您删除了ContentPresenter,因此DataGridCell无法显示其内容。它仍然在那里。 DataGridCell.Content是一个包含原始Text的TextBlock,而Template中的TextBlock是另一个。

So you'll get the correct Text by binding it to the Content.Text property of the TemplatedParent

因此,您将通过将其绑定到TemplatedParent的Content.Text属性来获取正确的Text

<TextBlock Text="{Binding RelativeSource={RelativeSource TemplatedParent},
                          Path=Content.Text}"/>

So, to sum it up. This works

所以,总结一下。这很有效

<ControlTemplate TargetType="{x:Type DataGridCell}">
    <Border BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
        <TextBlock Text="{Binding RelativeSource={RelativeSource TemplatedParent}, 
                                  Path=Content.Text}"/>
    </Border>
</ControlTemplate>

The data context of the data grid cell should be the data itself. So the binding should simply be:

数据网格单元的数据上下文应该是数据本身。所以绑定应该只是:

<TextBlock Text="{Binding}"/>
