扩展移动在WPF中的滚动条

Question

我有一个WPF DataGrid和DataGrid的每一行都有一个扩展显示行详细信息。扩展在扩展扩展首次移动滚动条。

我不想当扩张器扩张滚动条来移动。任何解决方案来解决这个问题？

到目前为止，我曾尝试以下，但它不是一个很好的解决方案。

   private void Expander_Expanded(object sender, RoutedEventArgs e)
    {
        ScrollViewer scrollViewer = GetVisualChild<ScrollViewer>(dgUsers);
        scrollViewer.ScrollToHorizontalOffset(0);
    }

由于我没有名誉权，现在我不能发布图片。

我附上了代码示例所以这将是其他人更容易重新创建他们的最终问题。

万一有人看此之后，尝试设置在ScrollViewer中的CanContentScroll属性等于False。
