The Datagrid have FreeColumnCount property- set it to 1 and see what happens.

Datagrid 具有FreeColumnCount 属性- 将其设置为 1 并查看会发生什么。

You do it with nested scroll viewers. Here's the Templateproperty setter for a Styleof TargetType="DataGrid":

您可以使用嵌套滚动查看器来完成。这是Templatea Styleof的属性设置器TargetType="DataGrid"：

<Setter Property="Template">
  <Setter.Value>
    <ControlTemplate TargetType="DataGrid">

      <DockPanel Dock="Top" HorizontalAlignment="Stretch">

        <ScrollViewer DockPanel.Dock="Top" 
                      CanContentScroll="False" 
                      HorizontalScrollBarVisibility="Disabled" 
                      VerticalScrollBarVisibility="Disabled" 
                      Focusable="false" 
                      Padding="{TemplateBinding Padding}">

          <DockPanel Dock="Top" VerticalAlignment="Stretch">
            <DataGridColumnHeadersPresenter DockPanel.Dock="Top" Grid.Row="0"/>
            <ScrollViewer HorizontalScrollBarVisibility="Hidden" 
                          DockPanel.Dock="Top" 
                          VerticalScrollBarVisibility="Auto" 
                          VerticalAlignment="Stretch" 
                          CanContentScroll="False" 
                          Focusable="false" 
                          Padding="{TemplateBinding Padding}">
              <ItemsPresenter VerticalAlignment="Stretch"/>
            </ScrollViewer>
          </DockPanel>
        </ScrollViewer>
      </DockPanel>

    </ControlTemplate>
  </Setter.Value>
</Setter>

Of course the ScrollViewercan also be styled to reflect your UI design.

当然，ScrollViewer也可以设置样式以反映您的 UI 设计。
