The current HttpContext of the request.


A Control that is associated with the Web Forms page where the SessionParameter is used.

Return Value

An object that represents the updated and current value of the parameter. If the context or the request is a null reference (Nothing in Visual Basic), the Evaluate method returns a null reference (Nothing in Visual Basic).

The SessionParameter object attempts to bind to the value of the session variable every time the Evaluate method is called.

The context parameter is used by the Evaluate method to retrieve the name/value pair that the SessionParameter object binds to. The control parameter is ignored.
