Event Handler Methods in Dynamics 365 for Operations (AX7)

by | Updated March 29, 2021 | Development, Dynamics 365 for Finance and Operations

In Dynamics 365 for Operations (AX7) the preferred mechanism for customizations to existing objects is to use event handlers to react to various events rather than overriding methods on tables, forms, and classes. For example, to change what happens when a button is clicked in AX 2012 you override the clicked method and put code either before or after the super() call. 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. Below is an example of an event handler method that reacts to the OnClicked event of a button on a form.

You can learn more about event handler methods and more in our online Dynamics 365 for Operations Development Workshop, beginning July 10! Detailed agenda and registration here.

    Thanks for the info Becky.

    When is the code in the Event Handler executed in relation to standard code that is executed in the event that it is subscribed to? For example, when the button is clicked, does AX execute its standard code first and then any event handlers subscribed to the event?

    Another question: do you think Microsoft will include automatic migration of event handlers built in 2012 to D365 format? (See “Event Handler Nodes in the AOT [AX 2012]” here: https://msdn.microsoft.com/en-us/library/gg839762.aspx )

    Hello Daniel:

    Unfortunately, with Event Handlers, it is difficult to know what the order of the event firing is. For example, having multiple objects subscribe to the same event can be interesting as we have no control over what fires first when the event is raised. If you need to have control of what is ran and when, I would recommend creating a class to control the sequence of events.

    In regards to your other question, I just asked four of our developers who attended the Dynamics 365 Tech Conference 2017 in Seattle, WA. They thought that it will be migrated but if the code is custom and over-layered then it will have to be reworked so that it is no longer a customization (over-layered).

    I hope this helps, if not I’d be happy to continue this conversation with you.
    Cheers,
    Brandon
