a list can be extended, meaning that every list as a sort of "triggers" like SQL Table. all you need todo is build something called " Event Receiver " and Attach it to the Event you want to capture. after you did that you can add any additional Action... Sound Easy ha.... :-) here is a sample EventReceiver: UnSafeDeleteEventReceiver class UnSafeDeleteEventReceiver : SPItemEventReceiver { #region Members private StorageManager m_oStorageManager; #endregion #region Properties public StorageManager oStorageManager { get { if (m_oStorageManager == null) { m_oStorageManager = new StorageManager(); } return m_oStorageManager; } } #endregion /// /// Checks for associated with current Item /// if exsist Item Deleteing is not premited. /// /// public override void ItemDeleting(SPItemEventProperties properties) { string[] ReceiverParams = properties.ReceiverData.Split('^'); StorageManager oStorageManager = new StorageManager(); SPListItem Item = properties.ListItem; SPList RelatedList = oStorageManager.GetList(ReceiverParams[0]); SPQuery Query = new SPQuery(); if (ReceiverParams.Length > 4) { if (ReceiverParams[4] != null && ReceiverParams[4] != "" && ReceiverParams[4] != string.Empty) { string q = System.Web.HttpUtility.HtmlDecode(ReceiverParams[4]); q = q.Replace("###", Item[ReceiverParams[3]].ToString()); Query.Query = q; } else { Query.Query = " " + Item[ReceiverParams[3]].ToString() + " "; } } else { Query.Query = " " + Item[ReceiverParams[3]].ToString() + " "; } SPListItemCollection items = RelatedList.GetItems(Query); if (items != null) { if (items.Count > 0) { properties.Cancel = true; properties.ErrorMessage = "This Item Cannot be deleted"; } } } } once we created this Class we need to attach it to the List, this is done by the following: we create an ExterderXml unsafe item deleting 3 10001 BlaBla.SharePoint.EventReceivers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=109625d57bdfbe68 BlaBla.SharePoint.EventReceivers. UnSafeDeleteEventReceiver JobList^### and on the FeatureXml we will add a referance to this Xml by the Following: on the ElementManifest we will add a new Tag : and on the root we will add : Good luck
