	IEnumerable dataSource,
	bool dataBinding


Type: System.Collections.IEnumerable

An IEnumerable that represents the data source used to create the control hierarchy.

Type: System.Boolean

true to indicate that the control hierarchy is created directly from the data source; false to indicate the control hierarchy is created from the view state.

Return Value

When extending the FormView class, you can override this method to create your own control hierarchy.
