Thursday, January 21, 2016 textbox yellowing in Chrome

I came across this issue when working with textboxes (auto fill on)   and tested on chrome browser. The textboxes are rendered with a yellowish background color.

This can be resolved in two ways.

1. Using CSS
    -webkit-box-shadow: 0 0 0px 1000px white inset;

2.Using jQuery
if (navigator.userAgent.toLowerCase().indexOf("chrome") >= 0) {
        var text = $(this).val();
        var name = $(this).attr('name');
        $('input[name=' + name + ']').val(text);

Monday, December 28, 2015 textbox allow < charactor to be saved

Normally, saving special characters such as < or > require special configuration settings to be enabled in web.config file and in the page itself.

1) Disable request validation in the page

<%@ Page title="test" .... ValidateRequest="false" %>

2) Set requestValidationMode in Web.config


This solution could expose unexpected security threads.  Jquery provides a nice workaround to overcome this issue by escaping < and > characters as shown below.

 function validateTxt() {
    $("textarea, input[type='text']").change(function () { //replaces in all text areas and textboxes
      html = $(this).val(); //get the value
      //.replace("a" , "b")  works only on first occurrence of "a"
      html = html.replace(/< /g, "<"); //before: if there's space after < remove
      html = html.replace(/
      $(this).val(html); //set new value

$(function () {
