Calling HtmlHelper's extension method from within a PartialView

Question

I'm trying to call a custom HtmlHelper's extension method from a partial view

<%: Html.ToRelativeTime(Model.CreatedDate) %>

and I get this error:

CS1061: ...does not contain a definition for 'ToRelativeTime' and no extension method 'ToRelativeTime' accepting a first argument of type 'System.Web.Mvc.HtmlHelper...could be found (are you missing a using directive or an assembly reference?)

and I'm calling the render code as this:

<% Html.RenderPartial("Product", Model.Product); %>

P.S: When I type Html., there is no intellesince.

Try to add namespace reference of your extension to the partial view where you trying to use your custom extension

<%@ import namespace='your namespace' %>

also here you may find a useful information

Yes this should fix it. I think the syntax is @import Models.MyHtmlHelpersClass or something similar. – Jack Sep 01 '11 at 18:14

yeah if using Razor.. but in the samples it's not looks so :) – Samich Sep 01 '11 at 18:27
If it's an HtmlHelper extension, I would prefer the web.config solution. – Timothy Strimple Sep 02 '11 at 07:13
Agree, all HtmlHelper extension should be located in the one place and registered via web.config – Samich Sep 02 '11 at 07:14
