編輯模板後處於禁用狀態的WPF滑塊

Question

我使用最新的Blend預覽來爲滑塊創建樣式。當我運行應用程序時，滑塊始終處於禁用狀態。只要刪除自定義樣式，它就會再次啓用。我看不出爲什麼會發生這種情況。 Blend生成

模板代碼如下：

 <Style x:Key="SliderStyle1" TargetType="Slider"> 
     <Setter Property="BorderThickness" Value="1"/> 
     <Setter Property="Maximum" Value="10"/>

一些Silverlight控件模板WPF的工作，而有的則沒有。滑塊是這些控件之一。
