Actually This is all I have in the web.sitemap file:
web.sitemap:
<?xml version="1.0" encoding="utf-8" ?>
<siteMap xmlns="http://schemas.microsoft.com/AspNet/SiteMap-File-1.0" >
<siteMapNode url="ABC" title="ABC">
<siteMapNode url="http://www.yahoo.com" title="Adequacy" roles="outcomesUser, administrators"/>
</siteMapNode>
</siteMap>
And this is the .aspx file:
demo.aspx:
<%@ Register TagPrefix="eo" NameSpace="EO.Web" Assembly="EO.Web" %>
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Demo.aspx.cs" Inherits="Demos_TreeView_Features_Populate_On_Demand_Demo" Title="Untitled Page" %>
<asp:Content ID="Content1" ContentPlaceHolderID="demo" Runat="Server">
<p>
EO.Web TreeView supports populate on demand. Populate on demand is useful when
the full content of the TreeView is too large to be all loaded up front.
</p>
<p>
To enable populate on demand, set the TreeNode's <span class="highlight">PopulateOnDemand</span>
to true and handles the TreeView's <span class="highlight">ItemPopulate</span> event.
</p>
<p>
The following TreeView use this feature to populate sub nodes when a parent
node is clicked.

<asp:SiteMapDataSource

<eo:TreeView runat="server" id="TreeView1" AutoSelect="ItemClick" ControlSkinID="None" Width="250px"

And this is the codebehind file(it's from the demo files. I did not change it)
demo.aspx.cs
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.IO;
public partial class Demos_TreeView_Features_Populate_On_Demand_Demo : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void TreeView1_ItemPopulate(object sender, EO.Web.NavigationItemEventArgs e)
{
//Get the parent node
EO.Web.TreeNode parentNode = (EO.Web.TreeNode)e.NavigationItem;
//Get the root path
string parentDir = Server.MapPath("~/Demos");
//Combine the root path with the node's Value property,
//in which we stores the relative path to the root
if (parentNode.Value == null)
parentNode.Value = string.Empty;
parentDir = Path.Combine(parentDir, parentNode.Value);
//Find all the directories
string[] dirs = Directory.GetDirectories(parentDir);
foreach (string dir in dirs)
{
string dirName = Path.GetFileName(dir);
EO.Web.TreeNode dirNode = new EO.Web.TreeNode(dirName);
//Directories can have child items. So at here we
//store the path associated with this directory to
//its Value property and set PopulateOnDemand to true
dirNode.Value = Path.Combine(parentNode.Value, dir);
dirNode.PopulateOnDemand = true;
parentNode.SubGroup.Nodes.Add(dirNode);
}
//Find all files
string[] files = Directory.GetFiles(parentDir);
foreach (string file in files)
{
string fileName = Path.GetFileName(file);
EO.Web.TreeNode fileNode = new EO.Web.TreeNode(fileName);
fileNode.NavigateUrl = "http://renaladvantage.com";
parentNode.SubGroup.Nodes.Add(fileNode);
}
}
}
If you can review it and let me know where I have done wrong, I would high appreciate it.
Thanks a lot!
