Render partial view with dynamic model in Razor view engine and ASP.NET MVC 3

Question

When I try to render a partial view whose model type is specified as:

@model dynamic

by using the following code:

@{Html.RenderPartial("PartialView", Model.UserProfile);}

I get the following exception:

'System.Web.Mvc.HtmlHelper<dynamic>' has no applicable method named 'RenderPartial' but appears to have an extension method by that name. Extension methods cannot be dynamically dispatched. Consider casting the dynamic arguments or calling the extension method without the extension method syntax.

However, the same code in a .aspx file works flawlessly. Any thoughts?

Answer 1

Just found the answer, it appears that the view where I was placing the RenderPartial code had a dynamic model, and thus, MVC couldn't choose the correct method to use. Casting the model in the RenderPartial call to the correct type fixed the issue.

Answer 2

Instead of casting the model in the RenderPartial call, and since you're using razor, you can modify the first line in your view from

@model dynamic

to

@model YourNamespace.YourModelType

This has the advantage of working on every @Html.Partial call you have in the view, and also gives you intellisense for the properties.

Answer 3

Can also be called as

@Html.Partial("_PartialView", (ModelClass)View.Data)
