My solution is based on dsuess user solution, which didn't work in IE for me, because I had to click one more time in the textbox to be able to type in. Therefore I adapted it only to Chrome:
$(window).on('load', function () {
if (navigator.userAgent.indexOf("Chrome") != -1) {
$('#myTextBox').attr('readonly', 'true');
$('#myTextBox').addClass("forceWhiteBackground");
$('#myTextBox').focus(function () {
$('#myTextBox').removeAttr('readonly');
$('#myTextBox').removeClass('forceWhiteBackground');
});
}
});
In your css add this:
.forceWhiteBackground {
background-color:white !important;
}
