When I select a record on the form and the status field(type enum) of the record is "start" then the button "pickup " in the form should be enabled.
Then I edit the record and update it from the form and the status becomes "stop". Then when I select the record , then the "pickup" button should be disabled.
Where should I write the code in form level ? At the data source of the form or in form>datasource>field(status)>method?
Could you show the code..I am a beginner in ax2012
