Visual Studio 2017设计器视图未显示控件

Question

我正在使用Visual Studio 2017进行可视c＃项目。我在Designer透视图中将控件添加到自定义用户控件中，并且在成功构建后，外观就是这样。

在某个时候，我正在撤消（ctrl + z）我在该UserControl类中犯的一些错误，现在Designer透视图显示了这一点

如果我构建并启动项目，仍然可以在弹出的窗体中看到所有控件。但是，如果我在Designer透视图中进行了任何更改，它将更新自动生成的代码，并且我将丢失所有已放入的控件，因此该表单现在为空。

如何获得Designer透视图以显示我已放入的所有控件？这很重要，因为我仍然需要添加一些控件，并且我不想重新创建所有内容。

这是自动生成的设计代码

如果我以任何方式更新Designer透视图，即使我只是调整窗体的大小，InitializeComponent方法中的所有内容都会重置。

Answer 1

我也遇到了Usercontrols的问题，我的控件无法显示。

原因是我确实将一些代码放入了在设计模式下正在执行的Usercontrol的Sub（）函数中（即使没有运行该程序！）

这段代码使设计人员崩溃，使我无法看到任何控件
