The rendering is indeed not handled the same when using InLine/InCell vs. Popup. For the latter, the editor template that is actually going to be used is inferred from the name, so you'd put a Product.cshtml template in ~Views/Shared/EditorTemplates.

This article covers this in detail: http://docs.kendoui.com/getting-started/using-kendo-with/aspnet-mvc/helpers/grid/editor-templates.
