I found there are not any controls for tabpage in ASP.NET 2.0. Well, we can use multiviews with menu. Each item in the menu has the name of views. Finally, we catch MenuItemClick event and set activeindex based on MenuEventArgs Text. Yes , we do like that. But I don't recommend this method. Firstly, this is not programming effect. I needs to two control and a new event catch. Moreover, a postback is triggered.
Last year, the power supply in my backup PC was burned out. Then I got a high-end one as the replacement. Now, my main PC got a serious over-heat problems. I need to swap them with my backup PC. I hope that will solve the problems.
