[Solved] Determine if there is a node selected in the TreeView with Javascript

[Greg Smith]

Is there a way to either get the count or search the TreeView recursively using Javascript to know if there is one or more selected nodes?

I have a multi-select TreeView and I need to disable a button when no nodes are selected.


Thanks
Greg

I always feel like a schmuck when I solve my own problems :s

<script type="text/javascript">

    // Are there selected items in the TreeView?
    function ItemsSelectedInTree()
    {
        var tree = $find("<%= RadTreeView1.ClientID %>");
        var selectedNode = tree.get_selectedNode();

        if (selectedNode != null)
        {
            // there is one or more selected nodes
            return true;
        }

        return false;
    }
</script>
