I am not familiar with Sharepoint so I probably cannot help much, but I hope it helps that I ask for clarification.

Do you still need help? If so, then are you now asking for help with a event handler for the ItemUpdated Event?

Thanks Suthish and Sam, i am current stuck with trying to write a sharepoint event handler that fires when i update a person & group field called and the single line text field be updated with the new Document Owner's Department. I tried writing the code in the ItemUpdated Event, but to no avail..

Below is the code i wrote into a ItemAdded Event Handler, it is working fine now..

public override void ItemAdded(SPItemEventProperties properties)
        {
            try
            {

                SPWeb web = properties.OpenWeb();
                SPListItem doc = properties.ListItem;

                doc["Document Owner"] = web.CurrentUser;
                doc["Document Author"] = web.CurrentUser;

                //if the field is people and group, can load name to show department too
                // doc["DocDepartment"] = web.CurrentUser;

                //loads mainsite with the current page's site URL
                SPSite mainSite = new SPSite(properties.WebUrl);

                //loads the ProfileManager of current site
                UserProfileManager mngr = new UserProfileManager(ServerContext.GetContext(mainSite));
                //Get the profile of the user that is retrieved above
                UserProfile up = mngr.GetUserProfile(web.CurrentUser.LoginName);
                //stores the department value of the above user
                string departmentVal = up["Department"].Value as string;
                doc["Document Owner Department"] = departmentVal;
                doc.Update();
            }
            catch (Exception ex)
            {
                Microsoft.Office.Server.Diagnostics.PortalLog.LogString("Item Added Exception : {0}", ex.StackTrace);
            }

        }

If you still need help, then it would help if you clarify your question; I sure don't understand what you mean by event handler.
