Question

我正在使用c＃和XAML开发一个Windows 8 metro应用程序。我做了分组项目页面，我在每个组之前都有一个重复的按钮列表。问题是我需要根据他所属的组来引用每个按钮，以便更改他将带我去的页面。这是我的页面的快照：

我需要在我的代码中引用社交媒体图标（facebook，google +，...）这是我的代码：

Answer 1

我这样做的一种方法是将所有按钮绑定到同一个命令，然后将command parameter设置为上下文中某些可识别的部分。您可以在命令参数上执行一组ifs来确定要执行的操作。

如何使用c＃和Xaml引用在windows 8 app中每个组之前重复的相同按钮？
