Using EventHandler

Declaration: 

        public event EventHandler UserSaved;

        public void OnUserSaved()

        {       

            if (UserSaved != null)       

            {       

               UserSaved(this, EventArgs.Empty);       

            }       

        }   

 

Event Trigger with parameter:

public void OnCustomerSelected(string customerBusinessKey)          
         {             
  if (!this.CustomerSelected.IsNotNull()) return;             
  var e = new CustomerEventArgs

                 {

                  CustomerBusinessKey = customerBusinessKey

                 };             
         

      this.CustomerSelected(this, e);         

          

}

Using Delegate

public delegate void CreateUserControlValidated(object sender, ValidationEventArgs e);

public event CreateUserControlValidated Validated;

 

public class ValidationEventArgs : EventArgs

{

    public virtual IList<string> ClientExceptionList { get; set; }

}
