推荐答案

在继承自 ListBox 类的类中，您可以使用 Protected GetTemplateChild():

From within a class that inherits from the ListBox class, you can use the Protected GetTemplateChild():

var myScrollviewer = myListBox.GetTemplateChild("ScrollViewer") as ScrollViewer;

如果您想从 ListBox 外部访问它，那么通过 Property 公开 ScrollViewer 应该可以工作，再次通过继承.

If you want to access this from outside the ListBox, then exposing the ScrollViewer via a Property should work, again through inheritance.

CAVEAT:如果您设置了自己的自定义模板，则此 Scrollviewer 可能不存在.您可以使用模板 Scrollviewer 名称而不是上述方法中的ScrollViewer".

CAVEAT: If you have set your own custom template, then this Scrollviewer may not exist. You can use the templates Scrollviewer name instead of the "ScrollViewer" in the method above.
