[Solved] client-side notification of node.expand()

[saurabh]

I use a radTree whose nodes have ExpandMode set to ServerSideCallBack.

At the client-side, I am able to fire _node.expand(); method to actually expand a given treeNode, but I am struggling to find a way for the notification of when the expand operation gets completed. That will help me in accessing the child nodes of a mode in Javascript.

Please let me know if there is any way.

Thanks,

Saurabh.

I think the event you are looking for is the OnClientNodeExpanding client-side event of the TreeView:

function OnClientNodeExpanding(sender, args)
{
    var node = args.get_node();
    alert("Node " + node.get_text()  + " is expanding!");
}

Calling the client-side expand() orset_expanded(true) method does not fireOnClientNodeExpanding and OnClientNodeExpandedclient-side events.

I am looking for some notification on the client side when the expand() operation finishes.

Hello Saurabh,

Please use OnClientNodePopulated event, it fires when the nodes are loaded on demand.
