- context
- HttpContext
The current HttpContext of the request.
- control
- Control
A Control that is associated with the page where the FormParameter is used.
Returns
An object that represents the updated and current value of the parameter. If the context or the request is null (Nothing in Visual Basic), the Evaluate(HttpContext, Control) method returns null.
Remarks
The FormParameter attempts to bind to the form variable every time the Evaluate method is called.
The context parameter is used by the Evaluate method to retrieve the value of the specified form field from the request. The control parameter is ignored.
