是否可以知道何时显示特定的全景项目 [英] Is it possible to know when a particular panorama item is displayed

问题描述

我有一个全景物品清单.

I have a list of panorama Items.

我想知道用户何时到达特定的全景物品，然后采取必要的措施.

I want to know when the user has reached a particular panorama item and then take necessary action.

我尝试在全景图项目上使用事件处理程序GotFocus，但是当用户到达该项目时不会调用该事件处理程序

I tried using the eventhandler GotFocus on the panorama item but it doesn't get invoked when the user reaches the item

推荐答案

全景控件具有

The Panorama control has a SelectionChanged event which is fired when the user pans from one item to the next. You can then use the SelectedItem or SelectedIndex properties to find the item which is currently in view.
