   using (SPSite site = new SPSite(siteurl))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    try
                    {
                        site.AllowUnsafeUpdates = true;
                        web.AllowUnsafeUpdates = true;
                        SPList list = web.Lists["AuditSystem"];
                        item["Owner"] = web.SiteUsers[DropDownListOwner.SelectedValue];
                         item.Update();
                    }
                    catch (Exception ex)
                    {
                        throw new Exception(ex.Message);
