Constructors

	Name	Description
	SimpleValueProvider(ModelBindingExecutionContext^)	Initializes a new instance of the SimpleValueProvider class by using the specified execution context.
	SimpleValueProvider(ModelBindingExecutionContext^, CultureInfo^)	Initializes a new instance of the SimpleValueProvider class by using the specified execution context and culture information.

Properties

	Name	Description
	ModelBindingExecutionContext	Gets the execution context.

Methods

	Name	Description
	ContainsPrefix(String^)	Gets a value that indicates whether the value provider contains the specified prefix.
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	FetchValue(String^)	When implemented in a derived class, returns the value for the specified key.
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	GetValue(String^)	Calls the FetchValue method and then uses the returned value to instantiate a new instance of the ValueProviderResult class.
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

This class does not contain the actual look-up mechanism; it delegates that to derived classes using the FetchValue method. Examples of simple value providers are the ViewStateValueProvider class and the ControlValueProvider class.
