Question

i’ve two classes.
One class (say A) takes a textbox in c’tor. and registers TextChanged event with private event-handler method.
2nd class (say B) creates the object of class A by providing a textbox.

how to invoke the private event handler of class A from class B?

it also registers the MouseClick event.

is there any way to invoke private eventhandlers?

Answer 1

Short answer: don’t.

Declare your event handler as public or, better yet, create a public proxy method, like

public class MyClass 
{
  private myHandler....

  public returnType DoClick() { return myHandler(...); }  
}

Giving direct access to a private member defeats the purpose of declaring it private.
