Avoiding Postbacks in ontextchange event

I am using a asp:textbox and it is firing ontextchanged event, and in that event I am binding the value to a session variable. My problem is that it postsback the page everytime, so I want to avoid the postback in that event.

Please assist me in doing the same.

If you want to handle the event on the Client-Side (JavaScript) then you should use onchange.

Now it is handled on the Server-Side because of OnTextChange is part of the asp:TextBox and is a server side event. Basicly Server-Side events = postback

OnTextChanged is a server event and if you want it fired and your session state updated correctly then the page needs to undergo a postback. Another approach is to use onchange which is a client event and to update your session state via javascript performing an ajax call to your back-end.
