JQuery to enable disable all asp.net controls placed inside div based on checkbox check uncheck

JQuery to enable disable all asp.net controls placed inside div based on checkbox check uncheckIntroduction:  In this article I am going to explain how to enable and disable all asp.net or HTML form controls e.g. textbox, dropdownlist, radiobutton, radiobuttonlist, checkbox, checkboxlist, multiline textbox (textarea) and button placed inside div tag based on checkbox selection as shown in demo image using jquery

Show image preview before uploading through fileupload control using jQuery

Description: While working on asp.net project I encountered the following requirement:
  • By default all the controls placed on the page need to be disabled
  • Enable all the controls placed on the page only when user checks the checkbox and on uncheck disable the form again .
Above requirement can be easily  implemented by server side coding by checking whether the check box is checked or not and based on that we can set the enable property of all the controls to true or false. 

But to make this process fast and to minimize the code I decided to implement it at client side using jquery and I am going to share that with all. The concept is very simple. Place all the controls inside a div tag and assign id to it(“myDiv” in this example ) and using jquery find all the controls contained in the div tag and then enable or disable them based on checkbox status(checked or not).

Implementation: Let’s check the concept by implementing it.

HTML Source Code:

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Enable Disable all form controls placed inside div based on checkbox check uncheck</title>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            EnableDisableControls();
        });
        function EnableDisableControls() {
            var status = $('#<%= cbApply.ClientID %>').is(':checked');
            if (status == true) {
                $("#myDiv").find("input, select, button, textarea").prop("disabled", false);
            }
            else {
                $("#myDiv").find("input, select, button, textarea").prop("disabled", true);
            }
        }
    </script>
</head>
<body>
    <form id="form1" runat="server">
        <div>
            <fieldset style="width: 370px">

                <div id="myDiv">
