Validation upon Leaving Page in NAV 2009

Hello. I am currently working on a project in NAV 2009 and I can't find a way on how to validate fields in creating a new customer in Customer Card. I would like to prompt an error message if a required field is empty upon leaving or closing the page. I tried TESTFIELD on the OnInsert, OnOpenPage, OnAfterGetCurrRecord but even though the page is still not opening, the error message appears. Is there any way on how to do this? Thank you.

    OnQueryClosePage(CloseAction : Action None) : Boolean

    Check what is the CloseAction then return EXIT(FALSE) so the page stays open.

    Yeah. I already have that. But it only executes when I close the page. It doesn't run when I switch to other pages.

    Set the page property RefreshOnActivate=Yes

    It's already set to Yes.
