Groupable/Scrollable virtual/page size

[NS]

Hi,

I'm using virtual scrolling and pageSize 50 on my grid to increase performance.  But now I also want to enable grouping but then it only groups the items in the page not all items.

How can I make that all items are grouped?

These are the settings I'm using:

$("#grid").kendoGrid({
        autoBind: false,
        selectable: "multiple",        
        dataSource: {            
            schema: {
                model: {
                    fields: {

                         
                    }
                }
            }
            ,
            pageSize: 50
        },      
        height: 'auto',
        filterable: true,
        groupable: true,
        scrollable: {
            virtual: true
        },
        pageable: {
            numeric: false,
            previousNext: false          
        },
        sortable: true,
        columns:            
    });

Hello,

Virtual scrolling with grouping is not supported as pointed in the respective section of the documentation:
http://docs.telerik.com/kendo-ui/controls/data-management/grid/appearance#limitations-for-virtual-scrolling

However, since R3 2017 release a new Infinite(Endless) Scrolling feature for the grid was implemented which works with grouping enabled without problems. More information about the new functionality is available below:
http://docs.telerik.com/kendo-ui/controls/data-management/grid/appearance#endless-scrolling

An online example can be seen at the following link:
