After calling web service you want bind data or any different logic. Secondly do you want to call through javascript or server side code.

I think better to handle this event on navigation link click.
That is handle event click on navigation link click and call the ajax method and then navigate to required url.

Required code will be like below

JavaScript

   $("a").click( // If you want to handle for specific link then use particular id
    function(event){
    
       event.preventDefault();
       //Do ajax call here
    } 
    );
}

Hope this will works. Good luck :)

That will stop the click working, you'll want to omit the preventDefault and just call the web method in the click event.

Which then might fail, depending on whether the browser stops all scripts running on the current page when navigating away from it. :)

Which is why doing these kinds of things are fairly pointless, especially if the call is important. Google analytics uses this method but obviously it's not a vital part of your site.

when i navigate to other page if the previous page has any temp files uploaded before loading the new page i want to clear the files uploaded from temp directory.for that i want call a web service method..

then we don't need event.preventDefault();. You can call ajax method.

in which event i can make a call?

You can create event handler for tag like this.
$("a").click(
function(event){

//Do ajax call here
}
);
