Question

I'm having following controller action to load rich text editor in a page

    public ActionResult Index()
    {            

        Editor Editor1 = new Editor(System.Web.HttpContext.Current, "Editor1");            

        Editor1.LoadHtml("~/brochuretemplates/myhtml.html");

        Editor1.MvcInit();

        ViewBag.Editor = Editor1.MvcGetString();

        return View();
    }

Initially above function load .HTML file to richtext editor content that contains inside the project.

I want to pass that changed content to another method how can I do that
