TreeNode remove method dosen't work
 

Hi all,
following is the client side javascript code I've written
to delete some nodes on treeview.
-----------------
var oTreeNode = TreeViewControl.getTreeNode(NodeIndex)
var oCNodes = oTreeNode.getChildren();

alert(oCNodes[0].getNodeIndex());
//Above line shows correct index.

oCNodes[0].remove();
//Above line doesn't work if oTreeNode collapsed.

-------------------
The remove method in above code doesn't work if the
oTreeNode is not expanded. I tried to expand it using
oTreeNode.setAttribute("EXPANDED",true); method. but It is
not working either.

Any ideas how can I expand the node and then remove it's
child nodes?
