Customserverbinding Groupable Statistics Problem

[Ray]

Grid Custom Server Binding Data

Group statistics have no data ，ClientGroupHeaderTemplate()  do not work；

GroupHeaderTemplate(g=>g.Count)，g.Count is Null

Custom Server Binding  the way How to implement group statistics？

 

Examples Code：

@model System.Collections.IEnumerable
@(Html.Kendo().Grid<Kendo.Mvc.Examples.Models.Order>()
    .Name("Grid")
    .EnableCustomBinding(true)
    .BindTo(Model)
    .Columns(columns => {
        columns.Bound(o => o.OrderID).Groupable(false);
        columns.Bound(o => o.ShipCity).GroupHeaderTemplate(g=>g.Count);
        columns.Bound(o => o.ShipCountry).ClientGroupHeaderTemplate("ShipCountry: #= value # (Count: #= count#)");
        columns.Bound(o => o.ShipName);
    })
    .Pageable()
    .Sortable()
    .Filterable()
    .Scrollable()
    .Groupable()
    .DataSource(dataSource =>dataSource
        .Server()
        .Total((int)ViewData["total"])
        .Aggregates(aggregates =>
            {
                aggregates.Add(p => p.ShipCountry).Count();
            }
        )
     )
)

Hi Ray,

A sample implementation on how to configure the grid is provided in this demo. Please examine the setup, apply the approach on your end and let us know how it goes.
