Ajax animation: Interpolated, question

[Bjorn Sagbakken]

I am using an Ajax animation method: Interpolated with the intention of
raising a button from flat look to outset mode on mouse hover over the
button. With the code below I get a client side error. I have suspicion to
the Property value, witch may not be "style" since the button has no style
property. Hovewer, I am not sure what value to use. Anyone with an idea?

<cc1:AnimationExtender ID="AnimationExtender2" runat="server"
TargetControlID="Button2">
<Animations>
<OnHoverOver>
<Interpolated Duration=".2" Fps="20" StartValue="None"
EndValue="Outset" Property="style" propertyKey="BorderStyle" />
</OnHoverOver>
</Animations>
</cc1:AnimationExtender>
