First delete the content from display from javascript
(ref: http://stackoverflow.com/questions/5933157/how-to-remove-an-html-element-using-javascript)
then call ajax to also remove it from database(ref: http://www.w3schools.com/ajax/)

1. jQuery is JavaScript
2. Where are you stuck?

Thanks for replying Ryan
firstly i dont think so that jquery and javascript are same.Yes they are client side scripting but are different.
I am stucked at the scripting part of javscript.What will be the code for contacting with
database and then delete it?

jQuery is just a library, written in JavaScript, to make using JavaScript much easier. In fact it has a method called .ajax() which is what you need to use to call a webservice. You do not want to write all the code necessary to call a webservice yourself.

Solution 1

There are two ways to do it.

1. Using WebMethod :
Create webmethod to delete data from sql server and call that webmethod from javascript.
Webmethod and javascript tutorial

2. Using Generic Handler :
Create a generic handler and call that handler from javascript method.

Hi,thanks for replying.
I am agree with your first option but if i opt for that option i wont be able to acecess the
page controls in my webmethod function so i wont be able to bind my listview after the record
gets deleted hence it wont show the updated data in listview.
And about your second option, Can you please put some light on the javascript code to call the generic handler.

thats true..... from webmethod you will not be able to access any serverside controls. if you want to bind your list view than you can retrieve json data from webmethod and using that json data you can bind your listview from javascript..... by the way can you tell is there any specific reason to use javascript only ?
