how to access Custom EventArgs class in Button click event?

Question

As a follow up to: access values within custom eventargs class

How do I access public variables within custom Eventargs class, using button click or any other method?

Answer 1

You can't do that. The EventArgs of the Click event is always of type EventArgs; you can't expect it to be of type TraderEventArgs, because the event args is created by the button, and the button doesn't know anything about TraderEventArgs. The only way it could work is if you create your own Button control that raises the event with a TraderEventArgs instead of an EventArgs
