Controls dynamically added in ASP.NET are lost after a postback

If you are loosing your controls added dynamically to a web page after a full or partial postback, is because you are not creating them in the Page.Init.

According to the ASP.NET Page Life Cycle, PostData (all values inputed on the client side) is applied between the Page.Init and Page.Load, so, if you add a control in the Page.Init, they will not lose their state and you don't have to recreate them.



        protected void Page_Init()
        {

        Control ct = ParseControl("");

        Page.Controls.add(ct);

        }
