Defining animations using the AnimationExtender is pretty cool... How can I use animation on the node hovered over instead of the entire control. For example I have this code:

<asp:TreeView ID="TreeView1" runat="server" DataSourceID="SiteMapDataSource1" />
            
<ajax:AnimationExtender runat="server" TargetControlID="TreeView1">
    <Animations>
        <OnHoverOver>
            <FadeOut Duration=".5" Fps="20" />
        </OnHoverOver>
        <OnHoverOut>
            <FadeIn Duration=".5" Fps="20" />             
        </OnHoverOut>
    </Animations>
</ajax:AnimationExtender>
