Maintain the state of dynamically added user control on postback?

Every server control that inherits the IPostBackDataHandler interface has a LoadPostData method that processes the postback data. When control is implemented by a class (page, form, placeholders, controls etc), that class calls the LoadPostData method and passes the posted data and key to maintain control states.

All you need to do is to re-instantiate / reinitialize dynamic controls before or within page load event each and every time during postback and add this control to page / forms / placeholders. Then the posted data will automatically be assigned to the control by calling LoadPostData method by the parent control.
