asp.net mvc - Returning an ActionResult from another ActionResult -

say have following code, mocked in notepad, excuse minor errors :)

//default page public actionresult index()     {         var musicviewmodel         {          albums = gettopsellingalbums(5),          genres = gettopgenres(5),          artists = gettopartists(5)          };          return view(musicviewmodel);     }  [httppost] public actionresult index(musicviewmodel musicviewmodel)     {          //for example, pretend have class called musicstoresubmission in         //viewmodel holds few different fields user fills out.          if(modelstate.isvalid)         {             //do actions based on user submitting form         }          //else, refresh page errors in modelstate.         var musicviewmodel         {          albums = gettopsellingalbums(5),          genres = gettopgenres(5),          artists = gettopartists(5)          };          return view(musicviewmodel);     } 

my point of concern in order postback errors modelstate being invalid, need generate viewmodel again elements on page use objects can created (genres, artists etc.). problem requires me copying , pasting of code actionresult actionresult, seemingly making code not dry.

is there better way of avoiding repeated code this? @ moment have moved generation of default objects viewmodel needs separate method and/or constructor, it's bit messy since have generate objects might need entire controller. hoping point second index action first index action , use regular method. i've tried few different ways of doing though , cant seem return actionresult actionresult.

any thoughts?

you can return actionresult method this:

[httppost] public actionresult index(musicviewmodel musicviewmodel) {     if(modelstate.isvalid)     {         //do actions based on user submitting form     }     return myaction(); } 

or pass posted model viewresult

[httppost] public actionresult index(musicviewmodel musicviewmodel) {     if(modelstate.isvalid)     {         //do actions based on user submitting form     }     return view(musicviewmodel); } 

the second approach better don't rebuild viewmodel
