I have to fire a custom java script code for checking some required fields are blank or not in an entity on Sub-Grid plus (+) onClick event. If the required fields are blank then Sub-Grid (+) button will not open the form of related entity and also fire an alert message that those fields have to filled up.
So, could You please tell me that "How could I find the id of Sub-Grid plus (+) button and onClick event to fire the custom java script code" for validating the required field of a parent entity?
