If you don't want to use any third party files then try writing yourself.
Javascript/JQuery should be your weapons for this.
You can use JQuery .keyup() function to put / automatically after 2/4 characters and also write logic to accept numbers and valid values for different section.

As suggested in the comments, jQuery will be the choice for you. Add a new JavaScript file to your project and add the following code to it. Make sure to reference it in the page for it to work. You will need a reference to jquery-1.10.2.min.js as well.

Using the Id of the control as inDate for explanation.

C#

$(document).ready(function() {
    $('#inDate').focus(function () {
        var inDate = $(this).val();
        if (inDate == 'dd/MM/yyyy') {
            $(this).val('');
        }
    });
    $('#inDate').blur(function () {
        var inDate = $(this).val().trim();
        if (inDate == '') {
            $(this).val('dd/MM/yyyy');
        }
    });
});

focus event will be triggered whenever the control with id = inDate gets focus. The blur event will be triggered when it looses focus. Refer the following links for more details.
