Hi,

From MSDN: 'The methods in a class are inherited by any class that extends it. You can alter the functionality of an inherited method by creating a method in the subclass with the same name and parameters as in the superclass. This is called overriding the method.'

Overriding a Method [AX 2012]

Generally speaking, this lead to OOP paradigms, class inheritance, so you can find more basic information:

Hi,

If you are looking for a table method to override, then right click on the methods and Override method will show you the available ones. You can find examples for all of them mainly in MSDN (and for some of them in the community forum) please use search. It is all about which functionality you want to extend, so you need to understand first what the standard method does before overriding.

Regards,

István

Overrideable methods are all listed in the documentation, you just have to look up the right object.

Like if you add a String edit to a form design, that is inherited from FormStringControl (https://msdn.microsoft.com/en-us/library/formstringcontrol.aspx - extends FormControl), who has a parent as FormControl (https://msdn.microsoft.com/en-us/library/formcontrol.aspx - extends Object, the parent of all AX classes).

So any methods which are not declared as private or protected with no method implemented on that object level (msdn.microsoft.com/.../aa676482.aspx) could override the methods.
