Nodes Does Not Show Up

This is my ASP code. I just took it from a sample:

<ignav:UltraWebTree ID="AccessTreeView" runat="server" Cursor="Default" ForeColor="Black"

Font-Size="8pt" Font-Names="Verdana" BorderColor="Pink" BorderStyle="Dashed" Height="400px"

Width="300px" Indentation="20" WebTreeTarget="ClassicTree" LoadOnDemand="Manual"

CompactRendering="False" EnableViewState="False" SingleBranchExpand="True" OnDemandLoad="AccessTreeView_DemandLoad">

<SelectedNodeStyle Cursor="Hand" CssClass="SelectClass"></SelectedNodeStyle>

<HoverNodeStyle Cursor="Hand" CssClass="Hover"></HoverNodeStyle>

<NodePaddings Left="5px"></NodePaddings>

<Padding Bottom="2px" Left="2px" Top="2px" Right="2px"></Padding>

<Levels>

<ignav:Level Index="0"></ignav:Level>

<ignav:Level Index="1"></ignav:Level>

</Levels>

<NodeMargins Top="2px"></NodeMargins>

<Styles>

<ignav:Style Cursor="Hand" ForeColor="Black" BackColor="OldLace" CssClass="HiliteClass">

</ignav:Style>

<ignav:Style BorderWidth="1px" BorderColor="DarkGray" BorderStyle="Solid" BackColor="Gainsboro"

CssClass="Hover">

<Padding Bottom="2px" Left="2px" Top="2px" Right="2px"></Padding>

</ignav:Style>

<ignav:Style ForeColor="White" BackColor="#333333" CssClass="SelectClass">

<Padding Bottom="2px" Left="2px" Top="2px" Right="2px"></Padding>

</ignav:Style>

</Styles>

</ignav:UltraWebTree>

This is my Page_Load code:

var AccessControlPopup = (PopupControl)RecordFormView.FindControl("AccessControlPopup");

var AccessTreeView = (UltraWebTree)AccessControlPopup.FindControl("AccessTreeView");

AccessTreeView.Visible = true;

var rootAccessGroups = GetChildAccessGroups("0");foreach (var accessGroup in rootAccessGroups)

{

var accessGroupNode = AccessTreeView.Nodes.Add(accessGroup.Name);

accessGroupNode.DataKey = accessGroup.AccessGroupKey.ToString();

accessGroupNode.ShowExpand = true;

}

AccessTreeView.DataBind();

AccessTreeView.ExpandAll();

When I step through the code, I clearly see that 1 node is being added to the collection  AccessTreeView.Nodes. However, when the tree view is displayed, it is completely empty.

This is my DemandLoad code, however it is not being hit so I think it is irrelevent:

protected void AccessTreeView_DemandLoad(object sender, WebTreeNodeEventArgs e)

{

foreach (var childAccessGroup in GetChildAccessGroups((string)e.Node.DataKey))

{

var childAccessGroupNode = e.Node.Nodes.Add(childAccessGroup.Name);

childAccessGroupNode.DataKey = childAccessGroup.AccessGroupKey.ToString();

childAccessGroupNode.ShowExpand = true;

}

}
