[Solved] RadTreeNode attribute changes not persisted to server

[Shane]

On the client, I'm perfoming the following treenode attribute update:

	function onNodeClicking(sender, args) {
	var treeNode = args.get_node();
	var attribs = treeNode.get_attributes();
	attribs.setAttribute("test", "54321");
	attribs2 = treeNode.get_attributes();
	alert(attribs2.getAttribute("test"));
	}

After the PostBack, the treenode's "test" attribute hasn't been updated and the original is rendered in the TextBox.

	protected void Page_Load(object sender, EventArgs e)
	{
	if (!IsPostBack) {
	RadTreeView1.Nodes.Add(new Telerik.Web.UI.RadTreeNode("Node1"));
	RadTreeView1.Nodes.Add(new Telerik.Web.UI.RadTreeNode("Node2"));
	RadTreeView1.Nodes.Add(new Telerik.Web.UI.RadTreeNode("Node3"));
	RadTreeView1.Nodes[0].Attributes.Add("test", "1234");
	RadTreeView1.Nodes[1].Attributes.Add("test", "1234");
	RadTreeView1.Nodes[2].Attributes.Add("test", "1234");
	}
	}
	protected void RadTreeView1_NodeClick(object sender, Telerik.Web.UI.RadTreeNodeEventArgs e) {
	TextBox1.Text = e.Node.Attributes["test"];
	}

I would assume this is a fairly common task and I'm just overlooking something.

Any help is appreciated!

telerik control is version 2009.1.402.35

Hello Shane,

You need to call two more methods in order to persist client-changes to the server:

sender.trackChanges();

attribs.setAttribute("test","123123");

sender.commitChanges();
