RadzenEmailValidator Class

A validator component that verifies whether a text input contains a valid email address format. RadzenEmailValidator uses the .NET EmailAddressAttribute to validate email format according to standard rules. Must be placed inside a RadzenTemplateForm<T> and associated with a named input component. Checks email format using System.ComponentModel.DataAnnotations.EmailAddressAttribute validation rules. Empty or null values are considered valid - combine with RadzenRequiredValidator to ensure the field is not empty. The validation runs when the form is submitted or when the component loses focus.
