As AlexeiXX3 mentioned, dynamically generated controls are not recreated after the page postbacks. The thing is that the postback resets the page to it's original state, so any information regarding the dynamically created controls is lost. Why is that? Because the Page class is stateless. The Page recreates child controls based on the tags in the aspx files, so your controls not being present there are not shown. What you need to do is recreate the controls in the OnInit event or any event that fires before PageLoad, or in PageLoad if you do a check to see is the page is posted back. See this article[^] as an example. The thing to keep in mind is that when recreating the controls to assign them the same ID they previously had. This way you will retain the state of the controls. That's because when you postback a page the values of the controls are saved in the viewstate, but when state is restored to the controls, it actually looks for the controls with the coresponding ID's on the page. If it can find them it will restore them. So you don't have to worry about state as long as you recreate your controls correctly.
