Question : ASP.NET button click

I have a button and few text boxes on my form.  I don't know why after the first click to submit the information from the text boxes to the server, the button does not generate any events any more.  I click on it after the first submit and have a breakpoint at the event handler for the button in the code behind but it does not show that the button generates any events at the second click onward so the program does not even get to the breakpoint the second time around.  What could be the problem that causes it to happen like that?

Thank you.

Answer : ASP.NET button click

I was not able to recreate the problem you describe. I pasted your markup and code into a new aspx page. My VS 2005 environment hit the breakpoint in the submit button click event every time.
