Update

public event Action<Account> Update

 The following example shows how to create an Update event. Once one of the account field is changed, Update event is triggered that evokes the method CurrentAccUpdate and deduces name of account.
 
using System;
using System.Collections;
using System.Collections.Generic;
using System.Text;
using System.Drawing;
using PTLRuntime.NETScript;

namespace AccountAction
{
    public class AccountAction : NETStrategy
    {
    	string accId;
    	
		public override void Init()
		{
			Accounts.Current.Update += new Action<Account>(CurrentAccUpdate);//Subscribes a method that is called each time when account parameters are changed.
			
			Account currentAcc = Accounts.Current; //creation and initialization of the object Account.
			
			accId = currentAcc.Id;
		}        
		
		//This function will be called after updating account information.
		private void CurrentAccUpdate(Account currentAcc) 
		{
			currentAcc = Accounts.GetAccountById(accId);//Selects Account by unique Id.
			Print("Account information update by account : " + currentAcc.Name);
		}
		
     	public override void Complete()
		{
			Accounts.Current.Update -= new Action<Account>(CurrentAccUpdate);//Unsubscribe.
		} 
     }
}
