Hello,

You can use the property  DataSourceID="WebHierarchicalDataSource1"  of  web menu to bind to WebHierarchicalDataSource  also you  have to set  the property TextField of ignav:ItemBinding tag and set column that you  will show in menu. For data source I use Northwind DB with employee -> orders tables relation.

 Please take a look at the sample code below:
<ignav:UltraWebMenu ID="UltraWebMenu1" runat="server" JavaScriptFilename="" WebMenuTarget="VerticalMenu"
            WebMenuStyle="DrillDown" JavaScriptFileNameCommon=""
            DataSourceID="WebHierarchicalDataSource1" TargetFrame="" TargetUrl="">
            <IslandStyle BackColor="LightGray" BorderStyle="Outset" BorderWidth="1px" Cursor="Default">
            </IslandStyle>
            <HoverItemStyle BackColor="DarkBlue" Cursor="Default" ForeColor="White">
            </HoverItemStyle>
            <Images>
                <XPSpacerImage Width="0px" />
                <SubMenuImage Url="ig_menuTri.gif" />
            </Images>
            <ItemStyle Cursor="Default" />
            <DataBindings>
                <ignav:ItemBinding DataMember="SqlDataSource1_DefaultView" TextField="City" />
                <ignav:ItemBinding DataMember="SqlDataSource2_DefaultView"
                    TextField="ShipCity" />
            </DataBindings>
            <DisabledStyle Font-Names="MS Sans Serif" Font-Size="8pt" ForeColor="Gray">
            </DisabledStyle>
            <Levels>
                <ignav:Level Index="0"  />
            </Levels>

Hope this helps.
