通过调用ScrollViewer.UpdateLayout（）方法，我们可以将scrollviewer的位置设置为垂直。我可以看到在使用/不调用ScrollViewer.UpdateLayout（）时在UI中更改垂直偏移值。但是，当我尝试从ScrollViewer.VerticalOffset
获取值时，该值不会被更改。

By invoking ScrollViewer.UpdateLayout() method, we can set the position of scrollviewer in vertical. I can see vertical offset value is changed in UI with/without invoking ScrollViewer.UpdateLayout(). But when i try to get the value from ScrollViewer.VerticalOffset which doesn't gets changed.

  ScrollViewer.ScrollToVerticalOffset(1905);

  //  ScrollViewer.UpdateLayout（）;

 // ScrollViewer.UpdateLayout();

更新此ScrollViewer.VerticalOffset的其他任何方式？

Any other way to update this ScrollViewer.VerticalOffset?
