Below are the Item Deleting event receiver code which prevents user from deleting an item with the notification./// <summary>/// An item is being deleted./// </summary>public override void ItemDeleting(SPItemEventProperties properties){ base.ItemDeleting(properties); properties.Status = SPEventReceiverStatus.CancelWithError; properties.ErrorMessage = "This item cannot be deleted, Please Check your admin Team"; properties.Cancel = true;}
If you remove the line "properties.Error Message = "This item cannot be deleted, Please Check your admin Team"; the code still works but there wont be any notification provided to the user.!!
