我有以下Checkbox.xaml
文件。我想在CheckBox
上應用兩種不同的Dropshadow
效果。所以我採取了兩個MultiTriggers
。我想刪除那些MultiTriggers
並將它們組合爲使用DataBinding
至Background
的Border
元素的單個觸發器。因爲Border
元素將因我應用的第一個觸發器而始終具有正確的背景。綁定背景到模板控件

你的問題是什麼? – Bernard 2013-04-07 13:44:55
我想用DataBinding背景來訪問觸發器中的'Border'元素的背景。 – 2013-04-07 13:48:03
我很困惑。你想通過'MultiTrigger'實現兩個不同的DropShadow效果。現在你想修改* Border *的背景,因爲某些原因。我不明白爲什麼。有點混淆整個事情。你能解釋一下嗎,這樣我可以提供一個解決方案嗎? – DHN 2013-04-07 13:56:48
