By default jquery ui draggable will not work with buttons. To make it work with button you need to set the cancel property value to false

Example:

Source code:

<!DOCTYPE html>
<html>
<head>
    <title></title>
    <meta charset="utf-8" />
    <link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">

    <script src="https://code.jquery.com/jquery-1.12.4.js"></script>
    <script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>

    <script language="javascript">
        $(document).ready(function () {
            $("#btndrag").draggable({
                cancel: false
            });
        });
    </script>
</head>
<body>
    <input type="button" id="btndrag" value="Drag !" />

Disabel or Enable all controls in a div using jquery

This example shows you how to disable or enable all controls/elements in a div using jquery. To disable all controls you need to set the disabled attribute value to disabled using jquery attr() method. to re-enable all the controls you need to remove the disabled attribute by using jquery removeAttr() method;

Syntax

//To disable
$("#divContainer").find("input, button, submit, textarea, select").attr("disabled", "disabled");

//To re-enable
$("#divContainer").find("input, button, submit, textarea, select").removeAttr("disabled");

Note
Anchor(hyperlink) elements don't support disabled attribute so we have to implement on click event as e.preventDefault();. To re-enable hyperlink we have to unbind the click event.
Syntax

//To disable
$("#divContainer").find("a").addClass("disablehyper").click(function (e) {
e.preventDefault();
});

//To re-enable
$("#divContainer").find("a").removeClass("disablehyper").unbind("click");
