Accessing "group" aggregate in GroupFooterTemplate using function notation.

[Jeremiah]

In the this documentation, you define a 'group' field that stores three fields - field, value and items. However, I am having trouble accessing this object in function notation. 

            let IsActive: kendo.ui.GridColumn = {
                field: "IsActive",
                title: "Active",
                aggregates: ["group"],
                template: `<span data-columnName="IsActive">#= IsActive #</span>`,
                groupFooterTemplate: (data: any, group: any) => {

                    return group.items[0].Name
                }
            }

See that 'group' is not defined in this context. How can I reference this in function notation?

Note: Data IS defined but does not include any group information.

Hi, Jeremiah,

When the groupFooterTemplate is declared as a function, the group field can be accessed through the data field itself.

groupFooterTemplate: (data: any) => {
     
    let group = data.IsActive.group;

    return group.items[0].Name
}
