Need dunamic Handle in AjaxControlToolkit.SliderExtender

Trouble is in the creating the Slider where Rail parted the Handel into two part with the different colors where color is generated according to Value

Hi,

My idea is you may add a valueChanged handler to the SliderBehavior component, and set the the color according to the value.

For instance:

<ajaxToolkit:SliderExtenderBehaviorID="slider"ID="SliderExtender1" runat="server" TargetControlID="TextBox1"
Minimum="0" Maximum="100" RaiseChangeOnlyOnMouseUp="true" Steps="5" RailCssClass="myclass" HandleImageUrl="../images/edit.gif">
</ajaxToolkit:SliderExtender>

function pageLoad(){

var slider = $find("slider");

slider.add_valueChanged(onValueChanged);
}

function onValueChanged()

{

var slider = $find("slider");
if(slider.getValue() > ? )

slider.set_RailCssClass(//a css class with a different back color);

}

Hope this helps.
