bout the application

The application Deleting child nodes illustrates how to delete child records when a record is deleted from the parent form.The applicationcomprises of two forms:

1. Client form to enter the client name (master form).
2. Client Details form to enter each client details (child form with lookup to the Client form).

Adding Deluge Script

When a record is deleted from the parent form (Client form), the on delete -> on validate script added to this form will delete all the child records corresponding to this client, from the Client Details form. To add the script in the Client form,

1. Select the from the Forms tab and click on More Actions -> On Delete -> Validate
2. Use the Delete Records task to delete records from the Client_Details form with the specified criteria.

on  delete
    {
        on validate
        {
            delete from Client_Details[ Client_Name == input.Name ];
        }
    }

The above script will delete the records from the Client Details form and then delete its parent record from the Client form.
