A very simple way for you to do this validation is with JQuery Mask.

Download the plugin here link and in your code you will do the following:

<asp:TextBox runat="server" ID="TxtData" data-mask="00/00/0000" />

Do not forget to initialize the plugin.

You can still create a class with your mask and use it on other parts of the system, like this:

<script>
      $(function(){
          $(".data").mask("00/00/0000", {placeholder: "__/__/____"});
      })
</script>

You can use the placeholder, as declared above to determine in the textbox how the value entered will be entered in the field.
