Just a suggestion - you guys might want to consider having minimum values for the height and width properties for the WebSlider
Paste the following snippets into a web form to see what I'm talking about:
<cc1:WebSlider Height="100" Width="125" Orientation="vertical" MaxValue="100" MinValue="0"
ID="WebSlider2" runat="server">
<Tickmarks NumberOfLabels="3">
</Tickmarks>
</cc1:WebSlider>
and
<cc1:WebSlider Height="350" Width="25" Orientation="vertical" MaxValue="100" MinValue="0"
Granted most developers will see this as a problem and will adjust the size accordingly but if you can stop it from happening in the first place that would make the control more user friendly
