I am using XForm for first time.

I have XFormTemplatePage as follows

[ContentType(DisplayName = "XFormPage", GUID = "de1ee296-9dcd-4d68-aad8-454d2d5f900f", Description = "")]
public class XFormPageTemplatePage : PageData
Name = "Formular",
Description = "Xform is used to get the user info.",
GroupName = SystemTabNames.Content,
Order = 4)]
public virtual XForm Formprop { get; set; }


and i have XformPage.aspx as follows

<%@ Page Language="c#" Inherits="Totalkredit.EpiServer.Views.XFormPage" CodeBehind="XFormPage.aspx.cs" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "">
<html xmlns="">
<head id="Head1" runat="server">
<style type="text/css">

hr {color:sienna;}
p {margin-left:20px;}
#name { color :red;}
.name { color :red;}
<form id="Form1" runat="server">
<%--@Html.PropertyFor(x => x.Formprop)--%>
<EPiServer:Property runat="server" PropertyName="Formprop" />


I get following error when i have created a simple form with 2 columns and save button  and click on save button. 




Server Error in '/' Application.

The table tblXFormData does not appears to have any columns that can be used by the system. Is this really a 'big table'?

I have never seen this error before. Is it a new EPiServer 7 site or is it upgraded from previous versions?

Jul 02, 2013 7:24

it is a new episerver 7 site. is there any error in XFormPageTemplatePage or XformPage.aspx above?


Jul 02, 2013 9:49

It is a Visual studio Episerver 7 MVC projekt

There error seems to be related to saving the form and that has nothing to do the templates using the form. I suggest that you start a support case to investigate this since I have no clue why you are getting this error.

Jul 02, 2013 9:55

If i look at the code it is not an MVC project since you are using webforms to create the template for showing the result. Try to connect your db to an empty episerver project based on webforms instead of mvc.

Thanks for your reply Eric.   It is actually a Mvc project.  as i am new to episerver and Xform, i thought also i am not doing it correctly.

So how should i write above code for mvc project? 

Jul 02, 2013 11:13

Now i have used following as template

[ContentType(DisplayName = "XFormPageTemplate2", GUID = "4562c1f8-1abd-4f9b-95c7-8b985d31df66", Description = "XFormPageTemplate2")]
public class XFormPageTemplate2 : PageData
Name = "XFormPageTemplate2",
Description = "XFormPageTemplate2 description",
GroupName = SystemTabNames.Content,
Order = 310)]
public virtual XForm XFormProperty2 { get; set; }


and i am using mvc 4 viewpage with layout (Razor) as follows

@model Totalkredit.EpiServer.Pages.XFormPageTemplate2
@using EPiServer.Core

Layout = "~/Views/Shared/MasterLayout.cshtml";

<h1>Xform Template2 page </h1>

@Html.PropertyFor(x => x.XFormProperty2)


still getting the same error when i have created a simple form with 2 columns with textbox  and button  

i get the error when i click on save button to save the form.

Try the below steps:


Page Type:


            Name = "Content",
            Description = "The Content will be shown in the main content area of the page.",
            GroupName = SystemTabNames.Content,
            Order = 4)]
        public virtual XhtmlString Content { get; set; }

        [Display(GroupName = SystemTabNames.Content, Order = 5)]
        public virtual XForm Form { get; set; }


  public virtual XForm XformContent { get; set; }


Base Controller class:

  //For XForm Page
        private readonly XFormPageUnknownActionHandler _xformHandler;
        private string _contentId;
        private readonly string _viewDataKeyFormat = "ViewData_{0}";
        private string ViewDataKey
                return string.Format(_viewDataKeyFormat, _contentId);

        public BaseController()
            _xformHandler = new XFormPageUnknownActionHandler();
            _contentId = string.Empty;

  #region"XForm Block"

        protected override void OnActionExecuting(ActionExecutingContext filterContext)
            if (!string.IsNullOrEmpty(_contentId))
                if (TempData[ViewDataKey] != null)
                    ViewData = (ViewDataDictionary)TempData[ViewDataKey];

        public virtual ActionResult Success(XFormPostedData xFormPostedData)
            return RedirectToAction("Index");

        public virtual ActionResult Failed(XFormPostedData xFormPostedData)
            return RedirectToAction("Index");

        public virtual ActionResult XFormPost(XFormPostedData xFormpostedData, string contentId)

            //var formData = new XFormPageHelper().GetXFormData(this, xFormpostedData);
            // var result = XFormActionHelper.DoAction(formData, xFormpostedData, true);
            //return this.RedirectToAction("Index");
            _contentId = contentId;
            return _xformHandler.HandleAction(this);




 public ActionResult Index(CustomFormPageType currentPage)

            var currentBlockID = (currentPage as IContent).ContentLink.ID;
            var viewDataKey = string.Format("ViewData_{0}", currentBlockID);

            if (TempData[viewDataKey] != null)
                ViewData = (ViewDataDictionary)TempData[viewDataKey];

            var pageRouteHelper = ServiceLocator.Current.GetInstance<PageRouteHelper>();
           // PageData currentPage1 = pageRouteHelper.Page;
            if (currentPage == null)
                var contentLoader = ServiceLocator.Current.GetInstance<IContentLoader>();
                //currentPage = contentLoader.Get<StartPage>(ContentReference.StartPage);
            var actionUri = string.Empty;
            if (currentPage.Form != null && currentPage != null)
                var urlResolver = ServiceLocator.Current.GetInstance<UrlResolver>();
                var pageUrl = urlResolver.GetVirtualPath(currentPage.ContentLink);

                actionUri = string.Format("{0}XFormPost/", pageUrl);
                actionUri = UriSupport.AddQueryString(actionUri, "XFormId", currentPage.Form.Id.ToString());
                actionUri = UriSupport.AddQueryString(actionUri, "failedAction", "Failed");
                actionUri = UriSupport.AddQueryString(actionUri, "successAction", "Success");
                actionUri = UriSupport.AddQueryString(actionUri, "contentId", currentBlockID.ToString());


            var model = new CustomFormPageViewModel()
                XformContent = currentPage.Form


            return View(model);



   <section id="xform">
                    <div @Html.EditAttributes(m => m.XformContent)>
                @using (Html.BeginXForm(Model.XformContent, new { Action = Model.ActionUri }))
