为了显示或隐藏你必须去绑定。

要扩展内容，请将DataTemplate作为StackPanel，并将TextBlock的Height属性（通过绑定）设置为显示两行所需的值。

在点击该项目时，只需获取selectedItem实例并增加height属性或设置为auto

要了解绑定，请参阅此处http://msdn.microsoft.com/en-us/library/windows/apps/cc278072(v=vs.105).aspx

In order to show or hide you have to go for binding.

And to expand the content, have your DataTemplate as StackPanel and set the Height property of TextBlock (through binding) with the value that is needed to display two lines.

And on tap of the item, just get the selectedItem instance and Increase the height property or set to auto
