[英]Visual Studio 2013 and C# - Unable to add event handler

---

I am working on WPF project, and after I made everything in Xaml file I wanted to start doing on my CS file. Now, I was trying to add event using that little bolt in properties, but everytime I click on any event (for example I select button in XAML and try to add -> MyButton_Click) i get a pop-up message "UNABLE TO ADD EVENT HANDLER".

我在WPF项目中工作，在Xaml文件中完成所有工作后，我想开始对CS文件进行处理。现在，我尝试在属性中添加事件，但是每次单击任何事件(例如，在XAML中选择按钮，并尝试添加-> MyButton_Click)，我得到一个弹出消息“无法添加事件处理程序”。

I hope you are able to help me.

我希望你能帮助我。

yes, @will is right, I also suffered from the same problem,when i was new in WPF.

Please check your x:Class in your XAML file,  it should include the namespace used in code behind.

e.g., x:Class="MainWindow" should be some thing like x:class="namespace.MainWindow" if it doesn't work,

try to restart the VS or try to recreate the project with correct name, hope it will solve your problem.

是的，@will是对的，我刚进入WPF的时候也遇到过同样的问题。请在XAML文件中检查您的x:类，它应该包括后面代码中使用的名称空间。例如，x:Class="MainWindow"应该是x:Class=" namespace "之类的东西。如果它不工作，尝试重新启动VS或者尝试用正确的名字重新创建项目，希望它能解决你的问题。
