Error executing child request for handler in view

I have an MVC 4 view where I render the following actions

@{
    Html.RenderAction("Index", "Logo");
    Html.RenderAction("Index", "MainMenu");
}

I have a form on my view which is filled out and posted to the controller. In the controller I perform some tasks and then send the model back to my view

[HttpPost]
public ActionResult Index(ManageAdministratorModel manageAdministratorModel)
{
     // I save some of the fields to the database here.
     return View(manageAdministratorModel);
}

When I'm redirected to the view I receive the following error

Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.

on this line

Html.RenderAction("Index", "Logo");

Any idea why this is happening?

Ok I found the problem, hopefully this will help someone in future.

The controllers for the partial views each contained the [HttpGet] attribute. For example

[HttpGet]
public ActionResult Index()
{
}

I remove the attribute from both controllers

public ActionResult Index()
{
}

and everything is now working.

I just got this error occurring in my razor when my partial view had a code formatting error in it.

If you click 'Continue' to get past the error, you'll see the actual error message displayed in the browser window that you loaded it from.

Correct the error in the partial view and it'll work!

Replace:

return View(manageAdministratorModel);

with:

return PartialView(manageAdministratorModel);

otherwise you might be ending in an infinite loop because you are rendering a view which is attempting to render a view which is attempting to render a view, ...

Also you might need to remove the [HttpPost] attribute from your child action.

The example of "Child Action Only" is:

     public class FiltersController : Controller
    {
        public ActionResult Index()
        {
            return View();
        }

        [ChildActionOnly]
        public ActionResult Departments()
        {
            string s = "Mahi and kallu";
            return View(s);
        }

    }

**for this am creating 2 views** 
1) Index:

    <html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
</head>
<body>
    <div>
         @Html.Partial("Departments","Filters")

</body>
</html>
**and for Departments View:**
<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Departments</title>
</head>
<body>
    <div>
       @Model      
    </div>
</body>
</html>


the ***childactions*** can be rendered with the help of "Partial" keyword.

Get rid of the layout @{ Layout = null; } in the child view.

I had exactly the same problem, and because I was using attribute routing, the inner exception error message was:

No matching action was found on controller ''. 
This can happen when a controller uses RouteAttribute for routing, 
but no action on that controller matches the request.

Remove the [HttpGet] attributes from action methods called by Html.Action() and it works. Nothing to do with routing.

I had this problem, It could happen because render engine can't find any view (corresponding to the name that is given in acton) I'd given wrong name of view (I mistakenly had given action name instead of view name) when I return view name and view model using PartialView() method, I corrected my view name and it worked fine

I had the same error. It began when I changed an action to another controller, so when running the program couldn't find the view in the folder. So if you move an action to another controller, also move the view to the respective folder's controller.

I got this error, but my problem was diferent. To see what is the error about, involve the line you get the error inside a try catch code, like this:

 try 
    {           
         @Html.RenderAction("Index", "Logo", new {id = Model.id});
    }
    catch (Exception e)
    {
        throw;
    }

Execute it with a break point at throw line and check the inner exception of the 'e'. My problem was that I'd changed the parameter name on my Controller and forgot to change it on my View.

It's easier to get the error using try catch.

I was facing the same issue but I put [HTTPGet] attribute over the function name and it worked for me.

[HttpGet]
//for Filter parital view
[ChildActionOnly]
public ActionResult Filter()
{ 
  // Your code will come here.
}

This happened to me, because I was calling the view from different areas.

The view I wanted to call was not within an area, so when calling it from outside of all areas a call like

@Html.RenderAction("Index", "Logo");

would work without problems.

But when I wanted that same view called from another view that was inside an area, I would have to add some additional information to the call to make it explicit:

@Html.RenderAction("Index", "Logo", new { area = "" });
