Hi Saritha, Please find enclosed attachedment. In this application I created a demo application. When you write 2 digit in a textbox. A event will fire (client side).and the data comes from web service. Now I am explaning what u want? You want to call data when i enter roll number in a textbox . You have to write a method in web service to get Data according to your roll no. Note that It should give result in a collection type. Now you can easily get your data in a "res". PFA attachment . Any query Please write. If you satisfied with my answer and demo. please mark it as answer. Regards , Ravi.

You need to code at the TextChange event of the textbox that you was going to do at the button.
