really I tryed several times to create hierarcial tree using the following properties

  • DataFiledID
  • DataFieldParentID

 but fails

here is the sample code

class
SiteDataItem
{
private string _text;

 

 

private string _url;

 

 

private int _id;

 

 

private int? _parentId;

 

 

public string Text

 

{

 

get { return _text; }

 

 

set { _text = value; }

 

}

 

public string Url

 

{

 

get { return _url; }

 

 

set { _url = value; }

 

}

 

public int ID

 

{

 

get { return _id; }

 

 

set { _id = value; }

 

}

 

public int? ParentID

 

{

 

get { return _parentId; }

 

 

set { _parentId = value; }

 

}

 

public SiteDataItem(int id, int? parentId, string text, string url)

 

{

_id = id;

_parentId = parentId;

_text = text;

_url = url;

}

}

 

 

 

 

protected void Page_Load(object sender, EventArgs e)

 

{

 

List

<SiteDataItem> siteData = new List<SiteDataItem>();

 

siteData.Add(

new SiteDataItem(1, null, "All Sites", ""));

 

siteData.Add(

new SiteDataItem(2, 1, "Search Engines", ""));

 

siteData.Add(

new SiteDataItem(3, 1, "News Sites", ""));

 

siteData.Add(

new SiteDataItem(4, 2, "Yahoo", "http://www.yahoo.com"));

 

siteData.Add(

new SiteDataItem(5, 2, "MSN", "http://www.msn.com"));

 

siteData.Add(

new SiteDataItem(6, 2, "Google", "http://www.google.com"));

 

siteData.Add(

new SiteDataItem(7, 3, "CNN", "http://www.cnn.com"));

 

siteData.Add(

new SiteDataItem(8, 3, "BBC", "http://www.bbc.co.uk"));

 

siteData.Add(

new SiteDataItem(9, 3, "FOX", "http://www.foxnews.com"));

 

RadTreeView1.DataTextField =

"Text";

 

RadTreeView1.DataNavigateUrlField =

"Url";

 

RadTreeView1.DataFieldID =

"ID";

 

RadTreeView1.DataFieldParentID =

"ParentID";

 

RadTreeView1.DataSource = siteData;

RadTreeView1.DataBind();

}

here is the output:

Note:

  • I'm using Rad controls for asp.net ajax.
  • the sample code copied from the online example.

Hi Moustafa,

You are probably using an older version of RadTreeView. Please make sure you are using the official one.
