RadCircularProgressBar cannot set width and heighth!

What ever height and width I set for the RadCircularProgressBar, the total pane never change its size.

Its so stange, I want a small RadCircularProgressBar, how can i do it? it just keeps its original size.

<telerik:RadCircularProgressBar Grid.Row="3" Grid.Column="0"         
         Maximum="100"  Height="50"
         Value="76" >
    <telerik:RadCircularProgressBar.ColorRanges>
        <telerik:ProgressBarColorRange Color="GreenYellow" Start="0" End="100"/>
    </telerik:RadCircularProgressBar.ColorRanges>
</telerik:RadCircularProgressBar>

Hi Guang, 

Can you send us the entire XAML, what is the parent layout control of the progress bar in this case? 

I am looking forward to your reply.
