In this article I will explain with an example, how to disable or prevent CUT, COPY, PASTE and DROP options in TextBox and Multiline TextBox (TextArea) using jQuery in ASP.Net Core MVC.
 
 
Controller
The Controller consists of following one Action method.
Action method for handling GET operation
Inside this Action method, simply the View is returned.
public class HomeController : Controller
{
    public IActionResult Index()
    {
        return View();
    }
}
 
 
View
The View consists of a HTML INPUT TextBox and a TextArea (Multiline TextBox) element.
The disable CSS Class have been assigned to the HTML INPUT TextBox and TextArea (Multiline TextBox) elements.
Inside the jQuery document ready event handler, all the elements having the CSS Class disabled are referenced and for each element, Cut, Copy, Paste and Drop event handlers have been assigned.
Inside the Cut, Copy, Paste and Drop event handlers, the event has been cancelled by calling the return false statement.
So, when user tries to perform Cut, Copy, Paste and Drop operations, the operation will not be performed.

    Layout = null;
}

    <input type="text" class="disable" />
    <br/><br/>
    <textarea rows="5" cols="5" class="disable"></textarea>
    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <script type="text/javascript">
        $(function () {
            var controls = $(".disable");
            controls.bind("paste", function () {
                return false;
            });
            controls.bind("drop", function () {
                return false;
            });
            controls.bind("cut", function () {
                return false;
            });
            controls.bind("copy", function () {
                return false;
            });
        });
    </script>
</body>
</html>
