c# - List View (index controller) does not update after an individual record has been edited -

i have mvc app multiple controllers reading/writing to/from ms sql database, , want consolidate database calls 1 controller (called xyzdataset.cs) instead of making calls db individual methods in each controller.

the situation is: when edit individual record, upon successful database update, i'm redirected index() method list of records displayed.

with scenario 1 (below), index() view displays updated list, freshly updated values.

with scenario 2, index() view not display freshly updated values; however, when go record edited, see newest values - so, database gets updated.

what culprit? have tried using both [outputcache(duration = 0)] , [outputcacheattribute(varybyparam = "*", duration = 0, nostore = true)] on controller , method level, not change outcome.

thanks hints on solution!

/*** items controller ***/     // scenario 1 - works charm, displays updated list in view after record has been updated: public actionresult index()     {     var itemlist = db.entityobj.include(i => i.status).orderbydescending(i => i.itemid);        return view(itemlist.tolist());     }       // scenario 2 - not display freshly made record edits, though changes recorded in db:      public actionresult index()     {     var itemlist = xyzdataset.getlist("a");        return view(itemlist.tolist());     }   namespace appspace.dal { public class xyzdataset {      private static mvctestsdbentities db = new mvctestsdbentities();      public static list<itemxyz> getlist(string viewtype)     {         list<itemxyz> itemlist = new list<itemxyz>();          switch (viewtype.tolower())             {             case "p":                  itemlist = db.entityobj.include(i => i.status).where(i=>i.statusid == 999).orderbydescending(i => i.itemid);                 break;             case "a":                  itemlist = db.entityobj.include(i => i.status).orderbydescending(i => i.itemid);                 break;             default:                 itemlist = db.entityobj.include(i => i.status).where(i=>i.statusid == 999).orderbydescending(i => i.itemid);                 break;             }          return itemlist;     } } 

}
