我在一个WP7用户控件中有以下的XAML标记。我的问题是当我的ListBox有超过一页显示不下的项目时,无法正常滚动。我可以通过手指向上滑动来滚动列表,但是一旦我松开手指,它就会跳回到列表的顶部(如果列表非常长,则即使在这种有限的范围内也无法正常滚动)。
我尝试了许多不同的布局,但都没有成功,例如将ListBox包装在ScrollViewer中、使用StackPanel替代Grid、删除WrapPanel并将其替换为Grid等。
其他类似的问题建议删除StackPanel(我已经删除了,但没有任何效果)或使用ScrollViewer(但也不起作用)。
托管用户控件的页面使用了GestureListener-我将其删除后仍然没有任何改变。
