Tooltip on a webcontrols' treeview

[appletonrd]

Hi there ppl,

I have this bit of code:

...
<iewc:treeview id="TreeView1" runat="server" onunhover="DisplayTooltip('')" onhover="DisplayTooltip(XXXX)">
<iewc:treenode id="Node1" text="Node One"></iewc:treenode>
<iewe:treenode id="Node2" text="Node Two"></iewe:treenode>
</iewc:treeview>
<DIV class="Tooltip" id="TOOLTIP" style="Z-INDEX: 999; LEFT: 0px; VISIBILITY: hidden; WIDTH: 264px; POSITION: absolute; TOP: 0px; HEIGHT: 50px"></DIV>
...

How do I reference the node that's being hovered, so I can parse it to the function that's going to show the tooltip?

Thanks.
