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.
