Silverlight]使用StringFormat設定Binding資料的顯示格式

在WPF中，TextBlock可以透過Binding的StringFormat屬性來設定資料的顯示格式，而其他的許多控制項也可以透過ContentStringFormat、HeaderStringFormat等等屬性來設定資料的顯示格式，那Silverlight呢?

這個時候，就有一個好消息和一個壞消息要和大家分享了，好消息是：Silverlight 4.0之後就可以和WPF一樣在Binding時使用StringFormat屬性來設定資料的顯示格式；壞消息則是Silverlight的控制項並不提供像WPF的ContentStringFormat等相關屬性可供設定(而且目前手邊的5.0 Beta版也沒有)。

這次就直接來看範例吧(請原諒我的懶惰，這次的範例是以WPF版的範例為基礎修改的)：

XAML檔內容如下：

雖然只能透過Binding來設定StringFormat屬性，不過在Silverlight中，還是可以透過控制項的Language屬性來達到當地化語系顯示的效果；而WPF中的HeaderStringFormat等等屬性，在Silverlight中也可以透過修改控制項的Template來達成一樣的效果，還是很方便的啦!!

如果需要參考和StringFormat相關的用法，可以參考以下MSDN連結：
