How to refresh particular part of my web page?

I wouldn't recommend Update Panel but you can use jQuery $.load() method which is pretty slick. Once you start using it, it helps you a lot.

So use Ajax... long story short.

Edit :

Maybe this article help as well :

In web forms you can use the update panel

See here for example

You can also use JQuery although it depends on what you are trying to do and to what complexity.

 $.ajax({
    type: "POST",
    contentType: "application/json; charset=utf-8",
    url: "YourPage.aspx/apply",
    dataType: "json",
    data: json.stringify(""),
    success: function (result) {
        alert(result);
        // window.location.href = "ClubCreation.aspx";
    },
    Error: function () {
        alert('error');
    }
});

     [HttpPost]
    public string apply()
    {
        return "Hi";
    }

You can use Ajax to solve your problem this code will help you
