请参阅我对该问题的评论。



你搞乱了两件事：事件调用和方法调用。您有一个用于处理事件的方法，因此您可以随时调用它。 这已经解决了您的问题。



但是现在，这听起来是一个糟糕的UI设计理念。此外，您应该了解，您只能从类中声明一个事件，声明相应的事件成员，而不是其他任何地方，甚至不是派生类。因此，您无法直接在任何其他类型的方法中调用事件。这是.NET的一个重要的万无一失的功能。 （当然，声明类型可以暴露一些间接调用事件的方法。）



您可以更方便地处理事件，其中包括获得相同效果的可能性通过调用方法处理事件，如果使用匿名方法。例如，您实际上并没有使用事件参数参数，因此处理起来可以更容易：

Please see my comment to the question.

You are messing up two different things: event invocation and just a method call. You have a method used to handle the event, so you can always call it. This is already a solution to your "problem".

But now, it sounds a bad UI design idea. Also, you should understand that you can only invoke an event from the class declaring corresponding event member, nowhere else, not even from a derived class. So, you cannot invoke the event directly in the methods of any other types. This is an important fool-proof feature of .NET. (Of course, the declaring type can expose some methods invoking the event indirectly.)

You can handle events more conveniently, which includes the possibility to get the same effect as the event handling by calling a method, if you use anonymous methods. For example, you are not really using the event arguments parameters, so the handling can be easier:

this.gridSigortaFirmalari.CommandCellClick += (sender, eventArgs) =>
{
   HandleCommandCellClick(); // you can call this method elsewhere
}
