Now the class file implementing the SPItemEventReceiver for item level event handling. All the levels have their respective EventReceiver (ex. SPListEventReceiver)

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using Microsoft.SharePoint;

namespace SDKSPEvents

{

public
class
SimpleEventHandler : SPItemEventReceiver

{

 

public
override
void ItemDeleting(SPItemEventProperties properties)

{

//base.ItemDeleting(properties);

properties.Cancel = true;

properties.ErrorMessage = "Deleting not Permitted";

}

}

 

 

public
class
sim : SPListEventReceiver

{

public
override
void FieldDeleting(SPListEventProperties properties)

{

properties.Cancel = true;

properties.ErrorMessage = "Deleting not Permitted";

}

}

}
