Quick note: Sitecore MVC partials

Here’s a bit of an obtuse trick that lets you use @Html.Partial() effectively on Sitecore MVC View renderings without specifying the full path to the partial you want to render. You might think that regular MVC syntax would work here:


But you’d be wrong. Instead, you’ll get an error that the partial could not be found, and the perplexing message that it tried to search [path-to-views]/Sitecore/_MyPartial.cshtml. Where’d that “/sitecore” come from? To understand this, a bit of background on how ASP.NET MVC resolves partials is in order.

The view resolution convention is based on the controller name that executes the view, not the view’s physical location. This makes sense in a pure ASP.NET MVC environment where every view is the result of a controller. However in a View Rendering, there’s just the cshtml. Except that in the background, Sitecore executes the View Rendering using a shim controller - a shim that goes by SitecoreController. This is where the /Views/Sitecore search path comes from.

So what’s the trick? Well, as long as all your views are in a MVC-like hierarchy, you can refer to the partial using the parent path:


This jumps out of the controller rendering folder (always Sitecore) and lets you specify the parent folder directly instead, without resorting to a full absolute path which - especially if you use areas or moved views around later - could break.

In case you’re wondering why I’m using native partials instead of @Html.Sitecore().Rendering() or @Html.Sitecore().ViewRendering() and such, these are static components of a MVC layout that are shared between multiple layouts - so it doesn’t make much sense to also register them as dynamic renderings and take the performance hit of that lookup.
