As the NavigateUrl property syntax illustrates, items can be added to and queried from the StateBag using the same syntax you could use to access items from a Hashtable.

You can therefore indicate that an entire page's view state need not be saved by setting the Page class's EnableViewState to False. (This can be done either in the code-behind class https://www.experts-exchange.com/questions/26424727/Viewstate-Errors-when-loading-dynamic-user-control.html Solution for this could be to clear all viewstate of these controls by method protected void ClearChildViewState () And for your last comment problem statement: When I did this, the result i.e. If, however, you set a DataGrid's EnableViewState property to False, you'll need to rebind the database data to the DataGrid on both the first page load and every subsequent postback.

The TrackViewState() method is called at the end of the initialization stage, which happens after the instantiation stage.

This collective state is what is persisted to the hidden __VIEWSTATE form field. These steps include managing view state, handling postback events, and rendering the page's HTML markup. In the instantiation stage, therefore, where we'd have something like HyperLink1.NavigateUrl = http://www.ScottOnWriting.NET;, it would only make sense that this information would be stored in the view state.
