MouseHover event

Hi,

I have a treeview and am using the MouseHover event to dynamically change a tooltip's content (probably the worst way to do it but...). In the parameters of the event, you get an "Object sender" and "System.EventArgs e". Does anybody know a way of tracking back to the treenode that is being hovered over by these parameters? I cannot use the selectednode property of the treeview because you can select a different node to that which you are hovering over.

Thanks in advance,
DJ
