@Html.Kendo()
   .TreeView()
   .Name("myThings")
   .DataSource(dataSource => dataSource
       .Read(read => read.Action("Index", "Employees"))
    ).DataTextField("Name")

and my controller code is

var employees = _context.Employees
    .Where(e => id.HasValue ? e.ReportsTo == id : e.ReportsTo == null)
    .Select(e => new {
           id = e.EmployeeID,
           Name = e.FirstName + " " + e.LastName,
           hasChildren = e.Employees1.Any()
    }
);

Kendo UI documentation on TreeView configuration property loadOnDemand says:

Indicates whether the child datasources should be fetched lazily when parent groups get expanded. Setting this to false causes all child dataSources to be loaded at initialization time. Note: when initializing the widget from an array (rather than from a HierarchicalDataSource instance), this option defaults to false, rather than true.

Consider using it.
