ASP.NET MVC3 - Html.RenderAction not working

Question

I'm developing a layout page in MVC application. The layout page has - Header - Content - Footer

Header has ogo, Welcome message, user info, several other links.

My question is, Should i design header as partial view or render it using Rendoraction. PartialView is working fine. But as this data does not depend on rest of the page, i want to call a controller action which returns a header view with its own model.

but HTML Rendor action is not working.

_Layout.cshtml

<body>
    <div class="main_page">
        <div id = "header">
            *@Html.Partial("HeaderPartial", @Model)*@
            @Html.Action("Header")
        </div>        
        <div id="body">
            @RenderBody()
        </div>
        <div id="footer">
        </div>
</body>

HomeController

public ActionResult Header()
{
  Var VModel = //Create Model;
  return View(VModel)  
}

header.cshtml

@model VModel
<div>
</div>

Error executing child request for handler

Your header.cshtml look's rare to me, but if you want to make your header view as a partial view

First:

Remove the layout using

@{
    Layout = null;
 }

Second To render this view on your layout use

@Html.Action("Header","Home", new { foo= @someElement}) <-- this element send values to your action

I removed the layout as you said on header.cshtml and used '@Html.Action("Header", "Home")'. I'm still getting same error - Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.

Code is same as above. IN Layout.cshtml I'm calling action method @Html.Action("Header", "Home") ActionMethod in HomeController gets called public ActionResult Header() { Var VModel = //Create Model; return View(VModel) } but breaks after returning the view(VMModel) with below error Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'

change the call from Action to RenderAction and put a try and catch to the whole controller

Since the Html.Action call is in the layout page you have to specify the controller

@Html.Action("Header", "SomeController")

If you want to use RenderAction call it like this in _Layout.cshtml

@{ Html.RenderAction("Header", "Home"); }
