[Solved] Batch editing and totals

[Anu]

I am using the Grid in the batch update/edit mode. I have a div/td outside of the grid to which I have to display sum of one of the grid columns. I tried using the viewbag approach, but though the value in view bag is updated everytime the sum changes, the value in the div/td does not change. The value that is computed when the page first time loads is the one that is always displayed.
Here is my code:

@(Html.Telerik().Grid<SampleMyComp.Models.Quota>("quota")
                          .Name("Grid")
                          .Editable(editing => editing.Mode(GridEditMode.InCell))
                          .DataKeys(keys =>
                              {
                                  keys.Add(k => k.QuotaId);
                              })
                          .Columns(columns =>
                          {
                              columns.Bound(e => e.TerritoryName).Width(100);
                              columns.Bound(e => e.ISSValue).Width(100)
                                  .Aggregate(aggreages => aggreages.Sum())
                                  .FooterTemplate(result => result.Sum)
                                  .ClientFooterTemplate("Total Sum: <#= Sum #>");


                                 //more columns here

                              columns.Bound(e => e.HPSDValue).Width(120)
                                   .Aggregate(aggreages => aggreages.Sum())
                                  .FooterTemplate(result => result.Sum)
                                  .ClientFooterTemplate("Total Sum: <#= Sum #>");

                          })

                          .DataBinding(dataBinding => dataBinding.Ajax()
                              .Select("AjaxBinding", "Home")
                              .Update("AjaxUpdate", "Home")
                              )
                           .ToolBar(tools =>
                               {
                                   tools.Insert();
                                   tools.SubmitChanges();
                               })
                          .ClientEvents(events => events

                                       .OnEdit("onEdit")
                                       .OnSubmitChanges("onSubmitChanges")
                                       .OnComplete("onComplete")
                                       .OnDataBound("onDataBound"))

                          .Sortable()
                          .Pageable()
                          )

 here is my controller :

public ActionResult Index()
        {
            QuotaData quotadata = new QuotaData();
           ViewBag.quota = quotadata.GetQuota();
            CategoryData prod = new CategoryData();
           ViewData.Model = prod.GetCategory();
            SetTotalValues();
            return View();
        }

[GridAction]
        public ActionResult AjaxBinding()
        {
            SetTotalValues();
            return View(new GridModel(QuotaRepository.All()));
        }
 [AcceptVerbs(HttpVerbs.Post)]
        [GridAction]
        public ActionResult AjaxUpdate(
            [Bind(Prefix = "inserted")]IEnumerable<Quota> insertedQuota,
            [Bind(Prefix = "updated")]IEnumerable<Quota> updatedQuota,
            [Bind(Prefix = "deleted")]IEnumerable<Quota> deletedQuota)
{
//updates to data done here
             SetTotalValues(); //calculate new sum values
            return View(new GridModel(QuotaRepository.All()));
}

 private void SetTotalValues()
        {
             //Do sum calulation here and add value to viewbag.

            ViewBag.SumOfQuotaValues = sumDetails;
        }

And in the view page I am trying to display the value as :
<td>
    @ViewBag.SumOfQuotaValues.SumValue
 </td>

Why is display on the UI not changing when there is change in the controller values and the viewbag value is updated??
Can I access the aggregate value and use it to display in the div/td??

Pls help, I am new to both telerik and mvc
