asp.net mvc 3 - How can I get my ViewContext.ViewBag to work with my code? -

i’m trying create htmlhelper allow me communicate across parent , child views. got tutorial here: https://gist.github.com/primaryobjects/8442193.

first created class , method this:

  namespace schoolin.helpers   {      public  static class viewbaghelpers      {      public static dynamic getpageviewbag(this htmlhelper html)     {         if (html == null || html.viewcontext == null) //this means page root or parial view         {             return html.viewdata;         }          controllerbase controller = html.viewcontext.controller;          while (controller.controllercontext.ischildaction)  //traverse hierachy root controller         {             controller = controller.controllercontext.parentactionviewcontext.controller;         }               return controller.viewbag;          }         }  } 

in child view add using statement:

  @using schoolin.helpers 

and

 @{html.getpageviewbag().pagetitle = "my custom property readable parent view"; } 

in parent view i’m trying this:

 @{ viewbag.title = viewcontext.viewbag.pagetitle } 

so guess have 2 problems. first don’t have access html.viewbag tutorial , in parent view can’t do...

  viewcontex.viewbag. 

any idea how can make work? help.

i managed working after couple of tweaks. make sure syntax correct , title set after partial rendered.

layout page (_layout.cshtml):

@using schoolin.helpers  @* nb. example did not include call partial. *@ @html.partial("_child")  @* following line must appear after partial rendered viewbag have been set. *@ @* nb. example missing semicolon. *@ @{ viewbag.title = viewcontext.viewbag.pagetitle; } 

partial view (_child.cshtml):

@using schoolin.helpers  @{html.getpageviewbag().pagetitle = "my custom property readable parent view"; }
