Using RenderAction(actionname, values) in MVC4 issue

Question

I need to display some child objects (Items) of an entity Request. Instead of Request I found it better to pass in a view that contains more info t

Answer 1

Usefully alternative:

@model CAPS.RequestInfo
...    
@Html.Action("Items", new { requestId = Model.Id })

This code returns MvcHtmlString. Works with partialview and view result. Doesn't require {} chars.

Answer 2

You need to use this syntax when calling the Render methods:

@{ Html.RenderAction("Items", new { requestId = Model.Id }); }

The @syntax, without the curly braces, expects a return type which gets rendered to the page. In order to call a method that returns void from the page, you must wrap the call in curly braces.
