You are creating a Windows Presentation Foundation application by using Microsoft .NET Framework 3.5.
You add a Slider control and two buttons to a window of the application. You write the following code fragment.
(Line numbers are included for reference only.)

01 <StackPanel Orientation="Horizontal">
02 <RepeatButton
03
04 Content="Left"/>
05 <Slider Name="slider"/>
06 <RepeatButton
07
08 Content="Right"/>
09 </StackPanel>

You need to control the position of the slider thumb by clicking the buttons on the window.
What should you do?
