# Aggregates

To make aggregates available on the client, configure them in the [`DataSourceAggregatesFactory`](https://www.telerik.com/aspnet-mvc/documentation/api/kendo.mvc.ui.fluent/datasourceaggregatesfactory). by using the `ToDataSourceResult()` extension method on the server, the results will be sent in the response object and can be used in group headers, footers or other client-side templates.

* The `Aggregates` method sets the aggregates.

```Razor HtmlHelper
    @(Html.Kendo().DataSource<ProductViewModel>()
        .Name("dataSource1")
        .Ajax(dataSource => dataSource
            .PageSize(10)
            .Read(read => read.Action("Products_Read", "Home"))
            .Aggregates(aggregates =>
            {
                aggregates.Add(product => product.UnitsInStock).Min().Max().Count();
                aggregates.Add(product => product.UnitsOnOrder).Average();
                aggregates.Add(product => product.ProductName).Count();
                aggregates.Add(product => product.UnitPrice).Sum();
            })
        )
    )
```
