    // The only node that must be handled is the CurrentNode.
    if (item.ItemType == SiteMapNodeItemType.Current)
    {
        HyperLink hLink = new HyperLink();

        // No Theming for the HyperLink.
        hLink.EnableTheming = false;
        // Enable the link of the SiteMapPath is enabled.
        hLink.Enabled = this.Enabled;

        // Set the properties of the HyperLink to
        // match those of the corresponding SiteMapNode.
        hLink.NavigateUrl = item.SiteMapNode.Url;
        hLink.Text        = item.SiteMapNode.Title;
        if (ShowToolTips) {
            hLink.ToolTip = item.SiteMapNode.Description;

    }
}

' Override the InitializeItem method to add a PathSeparator
' and DropDownList to the current node.
