SP.NET provides a couple of page-level state persistence mechanisms in ViewState and the new ControlState.
While both mechanisms work, they both have some limitations in that they are not deterministic for the application developer—ViewState can be turned off and can be very bulky, and ControlState can be set only from within a control implementation. In this article I'll show another, more flexible state mechanism using a PreservePropertyControl that allows automatic persistence and restoration of field values automatically without requiring ViewState.
