    To avoid overlayering you need to create EventHandler for both OnModified and onValidated events instead.

    Just create a new class "FormName_EventHandler", and add you code there.

    You can get snippets of code for event handlers, by expanding Events node of datasource field, right-clicking on desired event and selecting "Copy Event Handler Method"

    Code snippet will look like this after you will paste it in your new class:

    [FormDataFieldEventHandler(formDataFieldStr(*FormName*, *Form_DS*, FieldName), FormDataFieldEventType::Modified)]

    public static void Compiler_OnModified(FormDataObject sender, FormDataFieldEventArgs e)

    {

         place your code here

    }

    [FormDataFieldEventHandler(formDataFieldStr(CustPackingSlipJournal, CustPackingSlipJour, Compiler), FormDataFieldEventType::Validated)]

    public static void Compiler_OnValidated(FormDataObject sender, FormDataFieldEventArgs e)

    {      

    }

    Here is an article that you can refer to:

    Thanks Fedir and Sukrut

    Sure, I will follow based on your answers

    One things, If I want to use any override methods in form based on requirements then always need to use "Eventhandler class". This is the only way to use override methods in Form ?

    Please give me more shed on this.

    Thanks!

    You can also use approach with registerOverrideMethod to totaly override method on the form.

    Check this blogpost for more info: ievgensaxblog.wordpress.com/.../ax-7-how-to-override-form-data-source-field-methods-without-overlaying

    Don't forget to mark your question as "resolved" :D

    Thanks Sukrut,

    Means for customize for we no need to use "EventHandler" class for override methods. We can use override methods same like AX2012

    For Standard form ONLY we should follow  "EventHandler" class.

    is't correct?

    Why in customize form we no need EventHandler class for override methods?

    Please give me more shed on this.

    Thanks!

    Thanks Sukrut

    So, I can use eventHandlerClass and without eventHandlerClass in customized form for override methods. But eventHandlerClass is best way to do.

    right?

    Thanks!
