I can see what I want in the IG Finance example but I can't figure out how to do it.  It appears to be somewhere in the styles but there are a lot of styling in this example.  Can someone help me narrow it down?

I've noticed that the IG Finance example is using version 10.3.20103.2084. The version I have is 10.3.20103.2065. Is it possible that what I want isn't possible in 10.3.20103.2065?

I pulled this style from the IG Finance Stocks Dashboard example using 10.3.20103.2084:

<Style x:Key="XamZoombarStyle1" TargetType="ig:XamZoombar">

     <Setter Property="Template">
            <Setter.Value>
                    <ControlTemplate TargetType="ig:XamZoombar">
                            <Grid>
                                     <Canvas x:Name="HorizontalRootCanvasElement" Height="88">
                                                 <ContentControl x:Name="HorizontalThumbElement"
                                                                                HorizontalContentAlignment="Stretch"
                                                                                VerticalContentAlignment="Stretch" Cursor="Hand"
                                                                                Style="{TemplateBinding HorizontalThumbStyle}"
                                                                                UseLayoutRounding="False" Height="88">
                                                                <Grid Height="88">
                                                                          <Rectangle Height="88" Margin="7,0" Fill="#00000000" Stroke="#00000000"/>
                                                                </Grid>
                                                   </ContentControl>

When looking at 10.3.20103.2065 using Silverlight Spy I don't see the same elements under the HorizontalThumbElement Content Control.  

I'm attaching two screen shots from Silverlight Spy.  You'll notice that some of the elements have changed.  I can't upgrade because I'm only a trial user right now but I would like to keep evaluating.  Is it possible to get the same functionality out of 10.3.20103.2065 or do I have to upgrade?

Just the Zoombar from 10.3.20103.2065:

I’m sending you the Zoombar style from this sample application.

I will submit a feature request for this.
