    If the method is decorated with hookable attribute you can create pre or post event handler. Some protected methods are decorated with this attribute in standard application that's why you can create pre or post event handler for those methods , if those are not decorated then you can't create pre or post event for those methods, in that case you can use coc.

    Thanks Sukrut,

    I almost understand. One thing only. How I will came to know the method those I am going to use that is Hookable? Is there any specific significant mentioned in that hookable method ?

    Please give me more she'd on this

    Thanks!

    You are going to see protected methods like this

    [HookableAttribute(true)]

    protected void loadModule()

    {

    }

    Thanks Sukrut

    I beleive public method is already hookable method.

    Suppose the method I am going to use in Event handler i.e Non hookable method .

    Can I make it as Hookable method?

    OR

    Instead of making hookable,  shall I go for COC. I believe COC supports both hookable or Non hookable method.

    Please give me more she'd on this

    Thanks!

    Hi!

    Take a look at this discussion https://community.dynamics.com/ax/f/33/t/218894, maybe it will be helpful.

    Thanks Rustem

    Yes I go through the link. I understand almost.

    1. If I wants to do any Non hookable method to Hookable method then only I have to declare

    Hookable Attribute(True)

    Protected void calc()

    2. I already asked Instead of making hookable,  shall I go for COC. I believe COC supports both hookable or Non hookable method.

    Please give me more she'd on this

    Thanks!

    Yes. But if a method is explicitly marked as Hookable(false), the method can't be wrapped in an extension class.

    Yes you have to use coc now because any standard method you can not change now.

    1) You can't do this for the standard methods since that would require overlayering

    2) Just use CoC when you can.

    Hookable was just a way for MS to expose protected methods for event handlers. CoC came later and has mostly replaced event handlers (and will continue to do so with the new CoC capabilities of PU20).

    You will still need event handlers in many cases, mostly on the framework events on forms and tables. But hookable attribute on a protected method is not very important any more.

    Thanks everyone

    So, if I got the above error in any methods while using Event handler then I will go for COC instead of making hookable.

    Thanks!
