I have read through the documentation concerning the ability to use Custom Attributes from both the client side and the server side. While this is working beautifully when a custom attribute is added at the server side, modified client side, and then re-evaluted at server side. Where I am running into an issue is when I am adding a custom attribute client side, it is not being sent back to the server. Is this a bug, am I missing something, or is it just not designed to do this?
Thanks!

Code Sample: Click on Node to add Custom Attribute
Client Side. Click Submit button to see attribute not
accessible.
======================================
<%@ Page Language="C#" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e){
lblClientAttribute.Text = "--";
if (!Page.IsPostBack)
RadTreeView1.Nodes[0].Attributes.Add("ServerAttribute", "This is my Server Setting");
else
lblClientAttribute.Text = RadTreeView1.Nodes[0].Attributes["ClientAttribute"]; }
</script>
<script type="text/javascript">
function OnClientNodeClicked(sender, args){
var node = args.get_node(); alert(node.get_attributes().getAttribute("ServerAttribute"));
node.get_attributes().setAttribute("ClientAttribute", "This is my Client Attribute");
alert("Client Attribute Added: " + node.get_attributes().getAttribute("ClientAttribute"));}
</script>
<head runat="server"></head>
<body><form id="form" runat="server">
<telerik:RadScriptManager runat="server" OutputCompression="AutoDetect"></telerik:RadScriptManager>
<telerik:RadTreeView ID="RadTreeView1" runat="server" OnClientNodeClicked="OnClientNodeClicked">
<Nodes><telerik:RadTreeNode runat="server" id="node1" Text="Sample Node"></telerik:RadTreeNode></Nodes>
</telerik:RadTreeView>

<asp:Button runat="server" ID="btnTest" Text="Submit" />
</form></body></html>

Hello Charlie Bross,
You should call the trackChanges() / commitChanges() methods in order to persist any client-side modifications on the server side. More info can be found here.

I am having a similar problem, but i am using RadControls for ASP.NET (Q2 08, not the Prometheus)
The trackChanges and commitChanges are not available to me.
Can you point me in the right direction?
Thanks

Hi TriZetto,
Are you trying to use this client side or server side. I believe that these properties are client side only. This is how I am using it below...

function
setNodeAttr(ele, key){
var
tree = $find("tvwControls");
tree.trackChanges();
_currentNode.get_attributes().setAttribute(key, ele.value);
tree.commitChanges();
}
Hope this helps

Hello guys,
TriZetto, the "classic" treeview does not have trackChanges and commitChanges methods. Instead, it has the
UpdateState() method.
You can check this help article for more information:
Telerik RadTreeView Client-Side > The RadTreeView client object
