Hi, I am a beginner in C# ASP.Net. I tried a very simple program: make a textbox and a button, each time I hit the button, the number in the textbox should increase by 1. My program do not work for me. When I hit the button, the number in the textbox do not change at all. I am sorry to ask this "hello world" kind question. But, what I did wrong?
Thanks
