How do we get the node-id of the selected node from the combotree. onclick event get the node-id of the node.

I need help in expanding the node while using the function setValues.

example:
   
Folder1
    File1
    Folder2
        File2
        Folder3
            File31
            File32


In the above example if I am passing the node-id of the child "file32" to the function setValues. Then the nodes "Folder2", "Folder3" should automatically be expanded.

I am using the following code.
 <script>
 $(document).ready(function () {
     $('#cc').combotree('setValues', 1,2,20,40,10);   
});
</script>

Thank You for the Help !

I need help in disabling the checkall feature. Can someone please help me in that.
Actually my requirement is that Whenever the user will check or select the parent node then all its child node should not be checked or selected.

Only the checked Element or node will be marked as selected not the others like its child nodes.
