Hi All, Very Good Morning..

I got a small problem when handling the Unbeforeload.

My Problem: Based on Some count i need to show a pop-up window and if the count equals, I need to cancel the pop-Up.

Can i handle "X" button in Pop_Up window. If the user clicks on it, is it possible to show any error Message?

Requirement: If the user clicks on "X" button (Top-Right Corner) in Pop_up Window, it should act like Cancel button. As of now, it is submitting like "OK" button

Sample JS Code:
window.onbeforeunload = function () {
        window.returnValue = document.getElementById("hidAttachedCount").value;
        if (window.returnValue == "3") {
            CausesValidation = "false";
        else {
            return "Did you save your stuff?";
