Specify location for nodes loaded through WebService

[John]

Hi

I have a RadTreeView that initially loads some nodes (hierarchical) and then some of the nodes when expanded load more nodes through web service. What happens is that the nodes loaded through the WebService go below the nodes that were already loaded under that node, like this

- PreloadedNode
--- PreloadedNode
--- PreloadedNode
--- WebServiceNode
--- WebServiceNode

What I want is to display the WebService nodes above the Preloaded nodes like so

- PreloadedNode1
--- WebServiceNode
--- WebServiceNode
--- PreloadedNode
--- PreloadedNode

Is this possible?

Thanks a lot in advance! :)

Hello Bidan,

The only way to achieve this is to switch the positions of the nodes after they're loaded in OnClientNodePopulated event handler like this:

<script type="text/javascript">
        function nodePopulated(sender, args) {
            var node = args.get_node();
            for (var i = 2; i < node.get_nodes().get_count(); i++) {
                var subnode = node.get_nodes().getNode(i);
                node.get_nodes().remove(subnode);
                node.get_nodes().insert(0, subnode);
            }
        }
</script>

Thanks a lot Yana

It works fine, although it's a bit inefficient (add nodes in the DOM, remove them, then add them again)
