Is it possible to cancel the call to super() in a class method using Pre/Post Event Handlers in class extension?

I was wondering if there was a way to cancel the call to super like we can do in Form extensions in Form control event handlers. For instance:

public void method(Object _obj)
{

    super(_obj);

    // some logic

}

It seems like wishful thinking but, I need to call super only after that logic is executed.

So I was wondering if there was a way to cancel the call to super in the PreHandler of this method and then call it again in the PostHandler?

No, you can't somehow skip a piece of code inside a method. The only thing you can do is interrupting the whole execution by throwing an exception.

If you want to run something before the rest of the method, use a pre-method event. If you need to change code inside a method, you need overlayering or asking the author (most likely Microsoft) to make the logic extensible.

Hi Zain,

Did you tried the below approach.

FormControlCancelableSuperEventArgs eventArg = e as FormControlCancelableSuperEventArgs;

eventArg.CancelSuperCall();

That would be applicable to certain form control events, but not to pre-/post-event handlers as required by Zain.

He's clearly aware of this option, because he mentioned he wanted something "like we can do in Form extensions in Form control event handlers".
