1I suspect he's trying to construct controls that are passed back to the view. Perhaps in a jQuery post back. I'd prefer to have a partial view which i can render from a view or send back from a jQuery post, but yeah...griegs– griegs2010-01-18 04:54:43 +00:00Commented Jan 18, 2010 at 4:54

Is this what you want?
Using HtmlHelper in a Controller
EDIT
Use this;
System.IO.TextWriter writer = new System.IO.StringWriter();
var h = new HtmlHelper(new ViewContext(ControllerContext, new WebFormView("omg"), new ViewDataDictionary(), new TempDataDictionary(), writer), new ViewPage());
string g = h.TextBox("myname").ToString();

Are you saying that it doesn't work? These types have changed only minimally between ASP.NET MVC 1.0 and ASP.NET MVC 2. If it doesn't work then let us know what doesn't work.

@Eilon for posterity, it looks like System.Web.Mvc.WebFormView does not have a constructor that takes a single string.

Would this cause a memory leak with the text writer?
You can use method like this:
public static HtmlHelper GetHtmlHelper(this Controller controller)
{
var viewContext = new ViewContext(controller.ControllerContext, new FakeView(), controller.ViewData, controller.TempData, TextWriter.Null);
return new HtmlHelper(viewContext, new ViewPage());
}
public class FakeView : IView
{
public void Render(ViewContext viewContext, TextWriter writer)
{
throw new NotSupportedException();
}
}
