asp.NET MVC4 using partial views in partial views

Question

Let's assume I have 3 custom controllers: AController, BController and CControler and one default HomeController. Each of the first three controllers have a very unique partial view for them, let's name them APartial, BPartial, CPartial and these are invoked with AFunction, BFunction and CFunction with a template looking like:

public ActionResult XFunction
{
    /*put some data into a ViewBag*/
    return PartialView("XPartial");
}

Respectivelly, APartial.cshtml, BPartial.cshtml, CPartial.cshtml are in the Shared folder. What is the best way to return all three views in one page when HomeController's Index (ActionResult method) is called. I tried rendering each like:

using (StringWriter sw = new StringWriter())
{
    ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, "XFunction");
    ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
    viewResult.View.Render(viewContext, sw);

    return MvcHtmlString.Create(sw.GetStringBuilder().ToString());
}

then putting each into ViewBag's dynamic variables, but I have a feeling there has to be a way nicer solution.

I mean in another view that renders all three partials like so: @Html.Partial('partialview1') @Html.Partial('partialview2') @Html.Partial('partialview3') — Elger Mensonides

The problem is, I am calling this async and I cannot write @Html.Partial, because I replace my main div with the result, so either: I cannot do that OR I overlooked being able to call @Html.Partial inside my Home/Index.cshtml. I am going to try that. I'll let you know asap. — Andrius Naruševičius

RenderAction did the trick, but it was basically the same idea as you told, I think :) Thanks a lot :) — Andrius Naruševičius

Use RenderAction in your view. Good explanation is here: http://www.arrangeactassert.com/when-to-use-html-renderpartial-and-html-renderaction-in-asp-net-mvc-razor-views/
