Hi.. this question has been answered before but I get a different error! In my form class I tried to override modified method of dfCustomerId but the second argument gives me error: The 'QuotationTable' argument of the 'methodStr' compile-time function does not specify a known class. I tried to put the name of form class instead and still getting the same error!

The dfCustomerId_modified is public and written under runDialog method directly

I have the same question (0)

methodStr() checks if such a class and method exist and you indeed don't have the method in a class called QuotationTable. I also don't think that you can define the overriding method in a form data source. Instead, create a class for your method, create an instance in runDialog() and pass the instance as the third parameter of registerOverrideMethod().

Modifying a dialog field value at run time

Thanks for your response Mr. Martin... I'm a little bit confused about a couple of things:

1- I created a class in the form class but I tried many times to create an instance but it always gives me error.. making the new class public doesn't help either.

2- The third argument of registerOverrideMethod represents what? it should be overrideObject but which object will be overriden? the dialog instance?

1) You'll need to describe your problem before we can help you. Creating an instance of a class is the most basic step of object-oriented programming; I wonder what you may be struggling with there. Note that in F&O, you can't create a class embedded to a form; you need to add a class to your project.

2) The third arguments provides the object of which the method (the second argument) will be executed.

Thank you.. it simply worked!

I faced the problem that I can't set the value of dfCustomerName so I created the static method and assigned the dfCustomerName from the form to my private dialogField.

and this is the line code in the form class in runDialog method:
