DateTimePicker close() event

[mrwrighty]

How do I use the close() event.

Cannot seem to get it to work.

export function onDateOpen(args){ var weDate = args.object.page.getViewById("weekending"); //DateTimePicker Dialogs.alert({ title: "Warning", message: "You cannot select another date yet", okButtonText: "OK"}); weDate.close(); }
