- context
- HttpContext
The current HttpContext instance of the request.
- control
- Control
A Web server control that is associated with the ASP.NET Web page where the QueryStringParameter object is used.
Note This parameter is not used.
Returns
An object that represents the current value of the parameter. If the context or the request is null, the Evaluate(HttpContext, Control) method returns null.
Remarks
The QueryStringParameter object tries to bind to the query-string field every time that the Evaluate method is called.
The context parameter is used by the Evaluate method to retrieve the value of the specified query-string field from the query string. The control parameter is ignored.
