Is it possible to alter the auto generated event handler code within visual studio?

I would like to be able to control the default code that's generated for event's when I use one of Visual Studio's automatically generated blocks. The current template is as follows:

void HandlerName(object sender, HandlerEventArgs e) {
    throw new NotImplementedException();
}

I would like to change this to the following:

private void HandlerName(object sender, HandlerEventArgs args) {
    throw new NotImplementedException();
}

Namely it's the args argument that I always change.

UPDATE: Further to this it is policy that we also include comments for private members here, thus another use-case for my requirement is to also generate the default comment.

UPDATE 2: I now retract the reasoning for wanting to rename e to args due to evidence of a non-standard naming convention, however I still would like to override the template if possible for explicit access modifier and default comments.

In the case you still want to change something to the auto-generated code for event handler, I use this extension for Visual Studio since a couple of years.

It's very helpful to generate more clean event handler name. As you will see, instead of generating something like txtName_LostFocus, the extension will suggest to you a method with name like this: OnNameLostFocus.

This help getting rid of underscore and prefixes that we usually add to controls. The extension have a configuration screen to add all the prefixes that you want.

But everything I say is not helpful for answering your question. Here is where it help -> In the code that you can download, you can see how the engine works to replace the name of the event handler method and I'm totally sure that you can found a solution to rename any argument you want (if you still want) and also, add an explicit modifier.

I will try to find the solution and let you know of my progress.

UPDATE: You can also use Resharper who will automatically if you want add explicit modifier for you using the clean up engine.

I think the e comes from the delegate signature (delegate void HandlerEventHandler(object sender, HandlerEventArgs e)), so you can't change it without also changing the delegate signature...

Are you saying you want to change the auto-generated code when you create an event handler?

My answer is no, but I am not really sure why you would need to.
