WPF DataGridCell Template with TextBlock - Binding?

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

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 开发者_StackOverflowcorrect.

Any other ideas?

Suppose you have changed the DataGridCell Template to the following

<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.

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

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

So, to sum it up. This works

<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:

<TextBlock Text="{Binding}"/>
