Hi Johan,

If you are using ABC methods then -

    

  • 
Hide the Ok button.
    • 


  • 
Create another button and call it something appropriate like Exit or whatever.
    • 


  • 
In the Event:Accepted embed of the ExitButton place code like this:
    • 


      ! Check to see if any changes

      IF ~SELF.Primary.Me.equalbuffer(SELF.saved)

        CASE MESSAGE('The Record
has Changed|'|

                                     
&'Do you wish to Complete Change?',|

                                      
'Change Decision',|

                                     
ICON:Question,'&Yes|&No',2 )

          OF 1

                   
My action code here

                   
POST(EVENT:Accepted,?Ok)

          OF 2

                   
POST(EVENT:Accepted,?Cancel)

        END ! Case structure

      ELSE

                   
POST(EVENT:Accepted,?Cancel)

      END ! If structure

Best Regards,
