asp.net ajax sliderextender

hi ,

How to set the value to the sliderextender dynamically from the code behind(c#)..
say , i have the following sliderextender ,

 <asp:TextBox ID="txtslidetarget" runat="server" Visible="True">
 <asp:TextBox ID="txtslidebound" runat="server" Visible="true">
                                                            
 <asp:SliderExtender ID="SliderExtender1" runat="server" TargetControlID="txtslidetarget" 
 Length="150" Decimals="1" Minimum="0" Maximum="10" EnableHandleAnimation="true" BoundControlID="txtslidebound">
