Using Html.RenderPartial() in ascx files

I'm trying to use Html.RenderPartial in acsx file and I'm getting an error:

Compiler Error Message: CS1973: 'System.Web.Mvc.HtmlHelper' 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

<a href="/projects/<%=project.Id %>">
  <% Html.Label("fdf"); %>
  <% Html.RenderPartial("Pro开发者_如何学运维jectName", Model.Id); %></a></li>
 <%} %>

However I've import neccessary namespaces, so it won't be error at

<% Html.Label("fdf"); %>

Are there any methods to use Html.RenderPartial in ascx file?

The compiler cannot choose the correct method because your Model is dynamic. Change the call to:

<% Html.RenderPartial("ProjectName", (int)(Model.Id)); %>

Or any other datatype Id is.

In case anyone else made the same mistake I did:

@Model MyViewModel

This will treat your model as dynamic

@model MyViewModel

This is a correctly strongly typed view. Note the lack of capitalisation!

Note, that this is Razor, unlike the original question.

The only way i found to pass eg. an IEnumerable was to create a local variable and pass in this one. For Example @{ IEnumerable<Demo.Models.Friend> friends = Model.Friends; Html.RenderPartial("_FriendsList", friends); }

Html.RenderPartial("_FriendsList", (IEnumerable<Demo.Models.Friends>)(Model.Friends)); did not work!
