This example shows how to use aggregates in Telerik Grid for ASP.NET MVC which is ajax-bound.

The following aggregates are supported:

• Average
• Count
• Min
• Max
• Sum

To specify the aggregates for a column use the Aggregates method:

columns.Bound(o => o.UnitsInStock)
        .Aggregate(aggregates => aggregates.Count().Min().Max())

Aggregate results can be displayed in three locations:

1. In the group header:

   columns.Bound(o => o.UnitsInStock)
           .Aggregate(aggregates => aggregates.Count())
           .ClientGroupHeaderTemplate("<#= Title #>: <#= Key #> (Count: <#= Count #>)");
   

2. In the group footer:

   columns.Bound(o => o.UnitsOnOrder)
           .Aggregate(aggregates => aggregates.Average())
           .ClientGroupFooterTemplate("Average: <#= Average #>");
   

3. In the grid footer:

   columns.Bound(o => o.UnitsInStock)
           .Aggregate(aggregates => aggregates.Count().Min().Max())
           .ClientFooterTemplate(
               "<div>Min: <#= Min #></div>" +
               "<div>Max: <#= Max #></div>"
           );
