Or if you are facing any specific issue then please comment with screenshot if possible. 2. Hi, You can either ask microsoft to make this method Hookable or write the logic in form initialized event handler. - and ask Microsoft to add a suitable delegate to their code. If a method is replaceable, extenders can wrap it by using CoC, but they don't have to unconditionally call next. Yes you have to use coc now because any standard method you can not change now.

Some of those classes you should analyse and to make the minimum possible of the use of "customization" i'll show a easy way to make a method hock-able for event handlers. When this code is run, the system finds any method that wraps the DoSomething method.The system randomly runs one of these methods, such as the DoSomething method of the BusinessLogic1_Extension class.When the call to the next DoSomething method occurs, the system randomly picks another method in the CoC.If no more wrapped methods exist, the system calls the original implementation. The compiler doesn't enforce calls to next. To be replaceable, a method must also be wrappable. Hi, For example, In Dynamics 365 for Operations (AX7) you can react to the OnClicked event by copying the event handler method for the event and pasting the method into a class.

So, if your logic works fine even after calling all the private methods, you can use the form event handlers. Example: Enum conversion that uses a switch statement over enum values, where the default block has a throw. In the following example, anyMethod can't be wrapped in a class that augments anyClass1. If a method has the [Hookable(false)] attribute (which makes the X++ compiler not add the extra IL code), or if the method actually has pre/post handlers, the coverage will be fine.
