A small control that generates the HTML required for the jquery simple treeview

(Is loading VS2008, take this time to share the next small control, can not organize demo, only from the project copy part of the code)

JQuery simple TreeView needs such a piece of HTML

<ul class="filetree" id="treeFolder">
<li id="1"><span　 class="folder">Root</span>
　<ul>
　<li id="2" class="closed"><span　 class="folder">node1</span><ul></ul></li>
　<li id="22" class="closed"><span　 class="folder">node2</span><ul></ul></li>
　<li id="23" class="closed"><span　 class="folder">node3</span><ul></ul></li>
　</ul>
</li>
<li id="64"><span　 class="imagebase">root2</span></li>
</ul>

Put an empty <ul></ul> on this side, because that node has a child node, but we did not load him, when the user clicks the expand button in the expansion. Expand the time to go to the server to take a data on their own add, here is no nonsense.
