How can I get the result of the method Html.DisplayFor() in a C# Class, like in a View model or even in a Controller ? And not in the View Aspx or Razor.

[Edit]
In fact I have a table to display and depending on the number of record I use a Telerik table or a simple HTLM table.

For the moment I have a function in my view to get the string to display for each column so I use the same format for both tables.

<%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<ViewModels.OrderViewModel>" %>

<script runat="server" type="text/C#">

public string GetCellValue (String columnName, Order order)
{
        string value = "";
        switch (columnName)
        {
            case "Ref":
                value = order.order.Reference.ToString(); break;
            case "Etc":
                value = Html.DisplayFor(p => order.order.Etc).ToHtmlString();break;             
            case "Payment date": 
                foreach (Executions ex in order.executions)
                {
                    value += ex.Date.Date.ToString("yyyy-MM-dd") + " ";
                }
                break;      

I want to move this function out of my view in the ViewModel for example, but I do not know how I can call the function Html.DisplayFor() out of a view.

Don’t understand why would you want to do it, but…

using System.Web.Mvc;
using System.Web.Mvc.Html;

class Example {    

    void Method()
    {
       HtmlHelper<TModel> Html = new HtmlHelper<TModel>();
       MvcHtmlString result = Html.DisplayFor(prop => Model.Prop);
    }
}

After your edit, if you move GetCellValue to another place, maybe you will only need to do

       MvcHtmlString result = new MvcHtmlString(order.order.Etc);

as, it should only display its value as string (unless you have set up a template for it).
