Iterates through the System.Web.UI.WebControls.Parameter objects contained by the collection, and calls the Evaluate method on each one.
- context
- The current System.Web.HttpRequest that the System.Web.UI.WebControls.Parameter binds to.
- control
- The System.Web.UI.Control instance that is passed to each parameter's ControlParameter.Evaluate(System.Web.HttpContext, System.Web.UI.Control) method.
The control parameter is used by System.Web.UI.WebControls.Parameter objects contained in the collection to retrieve the System.Web.UI.Page and current System.Web.HttpRequest object that the System.Web.UI.WebControls.Parameter object binds to.
If the current value for the System.Web.UI.WebControls.Parameter object is different from the value cached in view state, the Parameter.OnParameterChanged method is called.
