确保正确命名您的命名空间，类和事件.确保正确的名称空间中的类后面的代码中具有GridView1_RowCommand.这很可能是错误.

当您重命名类或文件的名称而忘记同时重命名该类或相反时，也会发生这种情况.

Make sure that youre namespaces, classes and events are correctly named. Make sure that you have a GridView1_RowCommand in the code behind class in the right namespace. This is most probably the error.

It happens when you rename the name of the class or file and forget to also rename the class or vice versa.

这些是代码隐藏文件中不存在的事件处理程序.您必须添加它们，然后再进行操作就很好.

Those are event handlers that don''t exist in your code-behind file. You have to add them, and then it should be good to go.
