    Error "dictionary requires a model of type..."

    Hello all, Im new to .net MVC and Im getting an error that Im not sure how to solve.

    I'm trying to create a contact form, and have the controller, model, and a partial view to make it happen, but Im currently getting the following error:

    The model item passed into the dictionary is of type 'Umbraco.Web.Models.RenderModel', but this dictionary requires a model item of type 'umbraco.Models.ContactModel'.


    here is my Partial:

    @inherits Umbraco.Web.Mvc.UmbracoViewPage<umbraco.Models.ContactModel>
    <div class="ContactForm">
    @using (Html.BeginUmbracoForm<umbraco.Controllers.ContactSurfaceController>("ContactForm", "ContactSurface"))
                <div class="FieldGroup"><label>Name</label><input type='text' name="Name" id="Name" required/></div>    
                <div class="FieldGroup"><label>Email</label><input type='text' name="Email" id="Email" required/></div>
                <div class="FieldGroup"><label>Phone</label><input type='text' name="Phone" id="Phone" /></div>
                <div class="FieldGroup"><label>Company</label><input type='text' name="Company" id="Company" /></div>
                <div class="FieldGroup"><label class="TextAreaLable">Message</label><textarea name="Message" id="Message" required></textarea></div>
                <input type="submit" value="Send Message" class="button" />

    Here is my Model:

    using System;
    using System.Collections.Generic;
    using System.ComponentModel.DataAnnotations;
    using System.Linq;
    using System.Web;
    /// <summary>
    /// Summary description for ContactModel
    /// </summary>
    namespace umbraco.Models
    public class ContactModel
        public string Name { get; set; }
        public string Email { get; set; }
        public string Phone { get; set; }
        public string Company { get; set; }
        public string Message { get; set; }
        public int ThankYou { get; set; }
        // TODO: Add constructor logic here

    And my Controller:

    using System;
    using System.Collections.Generic;
    using System.Configuration;
    using System.Linq;
    using System.Net;
    using System.Net.Http;
    using System.Net.Mail;
    using System.Text;
    using System.Web.Http;
    using System.Web.Mvc;
    using umbraco.Models;
    using Umbraco.Forms.Mvc.DynamicObjects;
    using Umbraco.Web.Mvc;
    using Umbraco.Web.UI;
    namespace umbraco.Controllers
    public class ContactSurfaceController : SurfaceController
        public ActionResult ContactForm()
            //in case you need it
            var currentNode = Umbraco.TypedContent(UmbracoContext.PageId.GetValueOrDefault());
            var model = new ContactModel();
            return PartialView("ContactForm", model);
        public ActionResult ContactForm(ContactModel model)
            if (ModelState.IsValid)
                var sb = new StringBuilder();
                sb.AppendFormat("<p>Name: {0}</p>", model.Name);
                sb.AppendFormat("<p>Email: {0}</p>", model.Email);
                sb.AppendFormat("<p>Phone: {0}</p>", model.Phone);
                sb.AppendFormat("<p>Company: {0}</p>", model.Company);
                sb.AppendFormat("<p>{0}</p>", model.Message);
                SmtpClient smtp = new SmtpClient();
                MailMessage message = new MailMessage();
                message.To.Add(new MailAddress(ConfigurationManager.AppSettings["ContactAddress"]));
                message.From = new MailAddress(model.Email);
                message.Body = sb.ToString();
                message.IsBodyHtml = true;
                catch (SmtpException ex)
                //log or manage your error here, then...
                    return RedirectToUmbracoPage(1337); // <-My published error page.
                return RedirectToUmbracoPage(1336); // <-My published succes page.
            return CurrentUmbracoPage();

    The error is pointing out the code that renders the partial view, so I assume it might be an issue with the partial, but I don't know what it is.

    thanks for your time.

    has an override...

    @Html.Partial("ContactForm", new umbraco.Models.ContactModel())

    Hi Sam,

    if you want to call the action in your surface controller to render the Form you have to use HTML.Action("ContactForm", "ContactControllerName") to make a call to the controller.

    HTML.Partial just renders the partial without the trip to the controller. Then the way Mike describes is right.

    Regards David
