wpf C＃在資源文件中隱藏/顯示控件

Question

我第一次使用WPF，並且我正在根據切換按鈕在測試工具欄上顯示/隱藏組對象。

工具欄是通過資源字典中的模板創建的，我無法弄清楚如何使這個工作，因爲它看起來比winforms更多的問題。

在所有的例子中，我發現他們似乎都起作用，如果項目不是模板的，有沒有什麼辦法可以實現這一點。

我的代碼到目前爲止是在下面和失敗點是登錄togglebutton因爲我有x：名稱引用，顯然我不能做到這一點作爲其資源字典的一部分，所以我很難倒...

   <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

現在您的分組框被稱爲「tBtn」，但應該是你的切換按鈕。 （因爲你指的是它的財產IsChecked） 嘗試命名您的ToggleButton tBtn並重試
