wpf C＃在资源文件中隐藏/显示控件

Question

我是第一次使用WPF，并且正在尝试基于切换按钮在测试工具栏上显示/隐藏组对象。

工具栏是通过资源字典中的模板创建的，我无法弄清楚如何使它工作，因为与winforms相比，它似乎是一个更大的问题。

在我发现的所有示例中，如果没有模板，则它们似乎都可以正常工作，我有什么办法可以做到这一点。

到目前为止，我的代码在下面，故障点在登录切换按钮上，因为我有x：name引用，显然我不能将其作为资源字典的一部分来执行，所以我很困惑...

现在您的GroupBox被称为“ tBtn”，但这应该是您的ToggleButton。 （当您引用其属性IsChecked时）尝试命名您的ToggleButton tBtn并重试
