No HttpContext or WebPageContext in Template class about razorengine HOT 5 CLOSED

I found a solution to this issue. I use a non-template .cshtml view as a wrapper around the template. This allows it to have the context's set.

In the controller, there are two functions. One that returns the wrapper view, and a second called by the wrapper to actually compile the template with RazorEngine.

public ActionResult Edit(int id)
{   
   :
   // Create VM and such
   :
   return PartialView(vm);
}

[ChildActionOnly()]
public string EditTemplate(MyViewModel vm)
{
    return RazorEngine.Razor.Parse(this.MyTemplate, vm, "MyTemplateName");
}

Then, the View "wrapper" (Edit.cshtml) is;

@model MyNamespace.MyViewModel
@{ Html.RenderAction("EditTemplate", new { vm = Model }); }

Hope this helps.

This work-around fixed my issue even though it is a hack. Any idea if this is an issue that can be fixed?

I spent a few hours on this today. WebPageContext.Current is only available within a Razor view, hence your template rendering needs to occur within a view if you want to access Html helpers & ViewData.

I tried with no success to create a new instance of a WebPageContext from code outside of a Razor View.

This is why the above solution works - however it can be simplified. You do not need to call Html.RenderAction from within the View - you can just parse your template from within the View directly.

Thanks!

Is this really a bug within RazorEngine? It seems like the ASP.NET MVC API is just not designed to be used this way so there just is no easy way to provide this with RazorEngine.
Please re-open if I'm missing something here.
