Using an MVC HtmlHelper from a WebForm

Question

I'm in the process of adding some UI functionality to a hybrid WebForms/MVC site. In this case, I'm adding some AJAX UI features to a WebForms page (via jQuery), and the data is coming from an MVC JsonResult. Everything is working 100%, with one exception:

I would like to implement the XSRF protection of AntiForgeryToken. I have used it in combination with the ValidateAntiForgeryToken attribute on my pure MVC applications, but would like to know how to implement the Html.AntiForgeryToken() method in WebForms. Here's an example using a UrlHelper.

I'm having some trouble getting ViewContext / RequestContext "mocked" up correctly. How should I go about using HtmlHelpers within a WebForms page?

Edit: I'm looking to retrieve the AntiForgeryToken from my WebForms page, not from the MVC JsonResult.

Answer 1

I know this is an old question, but I ran into this issue today and thought I'd share. I'm working in MVC4 and have a webform control (.ascx) that's shared between both MVC (via RenderPartial) and WebForms. In that control, I needed an antiforgery token. Fortunately, there's a helper now you can use in your webforms now that's as simple as this:

<%= AntiForgery.GetHtml() %>

This will render your anti-forgery token like you would get in MVC.

Here's the MS link to it.
