You could possibly surprise how the validation UI was produced with none updates on the code within the controller or sights. The following code demonstrates the two Generate techniques.
Since the StoreManagerController supports the Edit ability, in this exercise you might find out how so as to add a Generate See template to Permit shop administrators include new Albums to the applying.
Top rated-degree nodes can use BindRequiredAttribute with validation characteristics. In the next case in point from the sample application, the CheckAge process specifies that the age parameter has to be bound within the question string in the event the variety is submitted:
