viewstate property

yo man - it can be used for several reasons. .net uses this object class internally to retain information on postback. a programmer can also use this to set specific object values to also retain values on postback. good luck.

ViewState is one mechanism in ASP .NET by which controls are able to retain their state between postbacks (requests for the same page). It is a "Page" level property and is maintained only for access to the same page multiple times and not across different page visits. The viewstate of a page is saved in a hidden form field __VIEWSTATE. It is passed as a base64 encoded string. Each control on a page as a property "ViewState" which it is responsible for populating, in oder to persist its state. ViewState can be used by developer to persist page level information: ViewState["Item"] = "rock" You can get it back using: string text = (string) ViewState["Item"];
