I am builing an ASP.Net mvc3 website which comprises of a series of forms all built on top of different models. Once the user fills up each form a "Confirm" page is shown which will show the fields of the form filled along with data in grid format to the user. I am facing difficulty in showing the Confirm view as the model keeps on changing for each form. Following is my Controller method for Confirm:

<pre lang="c#">public ActionResult Confirm(string ReqType)
        {
            var result = new List<dynamic>();
            if (ReqType == "AcctDesc")
            {
                DbContext.AcctDescDbContext objAcctDescDbContext = new DbContext.AcctDescDbContext();
                Models.AccountDesc objAcctDesc = objAcctDescDbContext.GetLatestRecord();
                ViewData["AcctDesc"] = objAcctDesc;
                ViewBag.ObjectModel = objAcctDesc;


                    var obj = (IDictionary<string, object>)new ExpandoObject();

                    obj.Add("Req_Name",objAcctDesc.Req_Name);
                    obj.Add("Req_Date",objAcctDesc.Req_Date);
                    obj.Add("ApprovalGroup",objAcctDesc.ApprovalGroup);
                    obj.Add("Account",objAcctDesc.AC_proposed);
                    obj.Add("Reason",objAcctDesc.AC_definition);
                    obj.Add("Language",objAcctDesc.AC_language);
                    obj.Add("CurrentShortText", objAcctDesc.AC_Currentshorttext);
                    obj.Add("CurrentLongText", objAcctDesc.AC_CurrentLongtext);
                    obj.Add("NewShortText", objAcctDesc.AC_Newshorttext);
                    obj.Add("NewLongText", objAcctDesc.AC_Newlongtext);

                    result.Add(obj);
                }
            ViewBag.result = result;
            return View();

            }

Following is the Confirm view:

@{
    ViewBag.Title = "Confirm";
    Layout = "~/Views/Shared/_LayoutMasterDataForms.cshtml";
}

<div>

@{
var grid = new WebGrid(ViewBag.result);

}

@using (Html.BeginForm())
{
<div id="grid">
@grid.GetHtml()
</div>
}
</div>
The problem is the gird is not getting rendered in the Confirm page-blank Html is coming up, what is the issue here? Please help.
