Hai Sasidhar OnShow and Onhide are not valid properties of ajaxcontroltoolkit:animationExtender, instead u can use OnMouseOver for OnShow and OnMouseOut for OnHide

Look at this http://www.c-sharpcorner.com/UploadFile/raj1979/AnimationExtender01242008065540AM/AnimationExtender.aspx

or

http://www.asp.net/AJAX/AjaxControlToolkit/Samples/Animation/Animation.aspx and check its properties
