You can call form methods, but it’s risky. The problem is that forms are not types, therefore you can’t call methods in a type-safe manner and maintaining code without any compile-type control is error-prone. It’s much better to move the logic from the form to a class and call the class. If your form contains business logic that needs to be used from other places, it’s a clear indication that the logic doesn’t belong to any form. If you want to do it anyway, look at my blog post Dynamic method dispatch in X++.

I’m ignoring the fact that clicked() is a form control method, not a form method. If you have any business logic in clicked() method, please go and change it now.

Either I already answered your question, or I don’t understand it and you should try to explain it in more details.

So what’s the issue in calling a class method in form?

You need to declare the class and using that object you can call the class methods.

void

{

YourClassName yourClassName;

clicked()

yourClassName.parmmethod();

}
