I have one solution for the same. But I am also looking for better options (for best option).
Thanks,
Below is the code I used to solve this case.
$(document).ajaxComplete(function (event, xhr, settings) {
window.setTimeout(function () {
if ($('.rdoEmail').is(':checked') || $('.rdoPhone').is(':checked')) {
$(".clsEmail_Number").focus();
}
else {
$("input[type='text']:visible:first").focus();
}
}, 0);
});
