validateDelete() - form data source methods - in D365 F&O

Question

Accepted Answer

The validateDelete() method is a standard method of a form data source, which is called when a user attempts to delete a record, to confirm the deletion.
Example
You have a custom form with a table named TrainingMaster. The table has a date field named TrainingDate. No backdated training data should be deleted.
The following code pattern can be a way to achieve this result:


[DataSource]
class TrainingMaster
    {
        public boolean validateDelete()
        {
            boolean ret;
        
            ret = super() && (TrainingMaster.TrainingDate >= today());
        
            return ret;
        }
    }


Note
You should throw an error with a message rather than let the validateDelete() method silently fail.
