Grid does not have expand / collapse icons

[William]

I can not figure out why the expand / collapse icons do not appear

@using Syncfusion.Blazor.TreeGrid;

<SfTreeGrid ChildMapping="Items" TreeColumnIndex="1" DataSource="@TreeData" TValue="treeitem" EnableCollapseAll="true">

    <TreeGridColumns>

        <TreeGridColumn Field="ID" HeaderText="ID" Width="160" TextAlign="Syncfusion.Blazor.Grids.TextAlign.Right"></TreeGridColumn>

        <TreeGridColumn Field="OrderDate" HeaderText="Order Date" Width="160" TextAlign="Syncfusion.Blazor.Grids.TextAlign.Right"></TreeGridColumn>

        <TreeGridColumn Field="SaleName" HeaderText="Sale Name" Width="100"></TreeGridColumn>

        <TreeGridColumn Field="NailCount" HeaderText="Nail Count" Width="100" TextAlign="Syncfusion.Blazor.Grids.TextAlign.Right"></TreeGridColumn>

        <TreeGridColumn Field="NailStripName" HeaderText="Nail Strip" Width="80"></TreeGridColumn>

        <TreeGridColumn Field="NailQty" HeaderText="Quanty" Width="100" TextAlign="Syncfusion.Blazor.Grids.TextAlign.Right"></TreeGridColumn>

    </TreeGridColumns>

</SfTreeGrid>

@code{

    public class treeitem

    {

        public string ID { get; set; }

        public DateTime OrderDate { get; set; }

        public string SaleName { get; set; }

        public int NailCount { get; set; }

        public string NailStripName { get; set; }

        public int NailQty { get; set; }

        public List<treeitem> Items;

    }

    public List<treeitem> TreeData = new List<treeitem>();

    protected override void OnInitialized()

    {

        treeitem Order1 = new treeitem() { ID = "Order1", OrderDate = new DateTime(2021, 2, 1), NailCount = 2, Items = new List<treeitem>() };

        treeitem Order2 = new treeitem() { ID = "Order2", OrderDate = new DateTime(2021, 2, 10), NailCount = 0, Items = new List<treeitem>() };

        treeitem Order1Item1 = new treeitem() { ID = "Order1Item1", NailStripName = "A-Lister", NailQty = 3 };

        treeitem Order1Item2 = new treeitem() { ID = "Order1Item2", NailStripName = "xyzzy", NailQty = 5 };

        Order1.Items.Add(Order1Item1);

        Order1.Items.Add(Order1Item2);

        TreeData.Add(Order1);

        TreeData.Add(Order2);

    }

}
