I am reading this article on HTML5 and asp.net. I am still using VS2008 pro. Do I need to install anything on my machine? How do I get started? I tried this sample. I don't see the message pop up. I am using IE10. When I tried on Firefox, the box turns red. Nothing happend on IE10.
<asp:textbox id="txtbx" runat="server" pattern="^\d*$" title="only numbers"/>
