I have this code, I get data from DB, and i need to create another column in grid with de sum of column1 and 2.

view Razor:

@model List<Project.Models.VW_VisitasPorNumeroVisitas>
 
@{
    ViewBag.Title = "Index";
}
 
 
 
<h2>Visitas por Numero de Visitas</h2>
 
@(Html.Telerik().Grid(Model)
        .Name("RadGrid1")
        .Sortable()
        .Filterable()
        .Pageable()
        .Footer(true)
        .NoRecordsTemplate("No hay registros")
        .Columns(columns =>
        {
            columns.Bound(o => o.NumVisitas)
                .Title("Numero de Visitas")
                .Aggregate(agg => agg.Sum())
                .FooterTemplate(@<text> Visitas Totales: <span >@item.Sum</span> </text>);
            columns.Bound(o => o.TotalVisitas)
                .Title("Cantidad de Visitas");
                 
            columns.Bound(o => o.NumVisitas)
                .Title("% Visitas");
        })     
)

CS:

public ActionResult Index()
{
    var visitasPorNum = from a in db.VW_VisitasPorNumeroVisitas
                        select a;
 
    return View(visitasPorNum.ToList());
}

Hello Eloy,

You could consider using the GridCalculatedColumn in order to achieve your goal. It allows making some operations with a list of fields from the grid datasource and display the result. See a demo here:

All the best,

Thx for reply, but i want to make it in razor view, and i can't put a GridCalculatedColumn.
i see the agreggate, but i only make it for the footer section of the column.

Hello Eloy,

It seems I missed this out - do you use an ASP.NET AJAX RadGrid or an MVC Grid? If it is the second, post your question in the MVC forums:

Kind regards,
