c# - ASP.NET MVC How to use PartialView in Layout? -

i need render menu in layout using partial view (if there better approach, please let me know). i'm doing way (in layout):

 @if (user.isinrole("admin"))    {       @html.partial("adminmenu")    } 

and how call in controller:

public actionresult adminmenu()   {       var = _amr.getadminmenu();       return partialview(am);   } 

so here partial view:

@model ienumerable<digitalhubonlinestore.viewmodels.adminmenuviewmodel>  <div class="dropdown">     <button class="btn btn-default dropdown-toggle" type="button" id="dropdownmenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">         admin menu         <span class="caret"></span>     </button>     <ul class="dropdown-menu" aria-labelledby="dropdownmenu1">         @foreach (var item in model)         {             <li><a href="@html.displayfor(modelitem => item.menuitemurl)">@html.displayfor(modelitem => item.menuitemname)</a></li>         }     </ul> </div> 

unfortunately it's not working.

you either have return menu collection in parent view, sending in pertinent model partial, or make htmlform, ajaxform or ajax call partial.

@html.partial("partials/adminmenu",model.adminmenuitems) 

or

//server   public actionresult adminmenu()   {       var = _amr.getadminmenu();       return json(am,jsonbehaviour.allowget);   }      //client     @using (ajax.beginform("adminmenu","admincontroller", null,           new ajaxoptions         {             onsuccess = "rendersuccess",             onfailure = "renderfailure",             onbegin = "renderbegin"         },         new         {             id = "frmvieweradminmenu",             name = "frmvieweradminmenu"         })     )     {     ...          <script type="text/javascript">             function rendersuccess(ajaxcontext){                /// ajaxcontext whatever comes getadminmenu()             }         </script>      ...     } 

or

--server render view

public actionresult adminmenurenderview() {     return partial("adminmenupartial",getadminmenuitems()); } 

--partial adminmenuviewdynamicloader

 @using (ajax.beginform("adminmenurenderview","admincontroller", null,       new ajaxoptions     {         onsuccess = "rendersuccess",         onfailure = "renderfailure",         onbegin = "renderbegin"     },     new     {         id = "frmvieweradminmenu",         name = "frmvieweradminmenu"     }) ) { ...     <div id="divadminmenucontent"></div>      <script type="text/javascript">         function rendersuccess(ajaxcontext){             $('#divadminmenucontent').html(ajaxcontent);         }      </script>  ... } 

--partial adminmenupartial

@model ienumerable<digitalhubonlinestore.viewmodels.adminmenuviewmodel>  <div class="dropdown">     <button class="btn btn-default dropdown-toggle" type="button" id="dropdownmenu1" data-toggle="dropdown" aria-haspopup="true" aria-expanded="true">         admin menu         <span class="caret"></span>     </button>     <ul class="dropdown-menu" aria-labelledby="dropdownmenu1">         @foreach (var item in model)         {             <li><a href="@html.displayfor(modelitem => item.menuitemurl)">@html.displayfor(modelitem => item.menuitemname)</a></li>         }     </ul> </div>
