Hello Abul,
I believe you can find a similar scenario in the online samples located here:
http://samples.infragistics.com/2008.2/webfeaturebrowser/default.htm
Just navigate to the "Client-Side Events" sample in the WebImageViewer samples area on the left and observe the behaviour when you hover the mouse on the button on the top left/right buttons.
You can see the source and especially the startScroll javascript method.
