Hi,

You will need to handle the TreeView's ClientSideOnDragDrop event. It will be something like this:

Code: HTML/ASPX 
<eo:TreeView ClientSideOnDragDrop="drag_drop_handler" ....>
....
</eo:TreeView>


Code: JavaScript 
function drag_drop_handler(treeView, srcNode, destNode, newIndex)
{
    //Cancel drag drop unless destNode is the parent node of srcNode
    if (srcNode.getParentGroup().getParentItem() != destNode)
        return false;
}


If you are not already familiar with the client side interface, you may wish to go over this topic:

Hope this helps.

Thanks
