我在FlipView中尝试了以下方法,将内部滚动视图的子元素的ManipulationMode处理为All。但是我面临的问题是,使用触摸滑动导航下一页时不会使用触摸,在鼠标情况下以及在操作模式下作为系统正常工作。我用下面的代码。
问题:触摸下一页的FlipView无法正常工作。
对于项目的子级StackPanels和VisualContainer ManipulationMode作为系统,它工作正常。但是在子项的子级StackPanels和VisualContainer ManipulationMode中都不能正常工作。
注意:我必须将子堆栈面板(Items,VisualContainer)ManipulationMode设置为ALL。 (本地:StackPanelExt是项)
在此附上示例代码段。
