动态更改ApplicationPage标头Windows Phone 8 [英] Dynamically change ApplicationPage Header Windows Phone 8

问题描述

您好， 

您能否建议我在LongListSelector中向上/向下滚动时触发的事件。它有ItemTemplate，它包含StackPanel和少量TextBlocks。当滚动结束时，我必须采用当前关注的StackPanel上下文。目的是使用来自StackPanel的数据更新
页眉。

感谢您的建议，

Nikola

Hello, 

Can you suggest me an event which fires when I scroll up/down in LongListSelector. It has ItemTemplate which contains StackPanel and few TextBlocks. I have to take the currently focused StackPanel`s context when the scrolling is over. The purpose is updating page header with data from StackPanel.

Thanks in advice,

Nikola
