[Solved] Multiple checked CheckBox value in code behind returns zero in ASP.Net

I tried getting multiple checked checkbox value. But the checked select only works for a single checked box. If i check more than 1 select box, the response is 0 but if i check only one select box, it displays the id correctly. 

protected void ImageButton3_Click(object sender, EventArgs e)
{
    int id = 0;
    int.TryParse(hfCheckedIds.Value, out id);
    Session["DatakeyValue"] = id;   
    ClientScript.RegisterClientScriptBlock(this.GetType(), "", "alert('" + id + "')", true);
}

$(function () {
    GetEmployees(1);
    var checked = [];
    $('[id*=chkSelect]').on('click', function () {
        if ($(this).is(":checked")) {
            checked.push($(this).closest('tr').find('td').eq(1).html());
        } else {
            checked.pop($(this).closest('tr').find('td').eq(1).html());
        }
 
        $('[id*=hfCheckedIds]').val(checked.join(','));
    });
});
 
$(document).on("click", '.Pager .page', function () {
    GetEmployees(parseInt($(this).attr('page')));
});
 
$(document).on('click', '.view', function () {
    $('[id*=hfId]').val($(this).closest('tr').find('td').eq(1).html());
});
