Set ClientIDMode on your textboxes to static, otherwise the id that gets rendered looks like ctl_blahblahblah...

I tested your code. It worked as expected. I do agree that you may consider adding the ClientIDMode Attribute so that asp.net renders the HTML element with that ID.

I did not add it in my example and when I looked at the HTML source code, ASP.NET used the same IDs without having to use ClientIDMode. However, as a rule of thumb, whenever I integrate javascript/jQuery, I always set this attribute.

Here is my complete example... maybe you forgot to include the reference to the jQuery library in your <head> section. In the example below, i did not include the onclick event for your submit button...

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>
