Remarks
The CompositeDataBoundControl class serves as the base class for a composite server control that binds to data from a data source. A composite server control is a control that is built from a combination of other server controls. Page developers do not use the CompositeDataBoundControl class directly; instead, they use controls that derive from this class. Examples of composite data-bound controls include the DetailsView, FormView, and GridView controls.
Classes that inherit from the CompositeDataBoundControl control must override the CreateChildControls(IEnumerable, Boolean) method to create the control hierarchy. To access the child controls of a composite data-bound control, use the Controls collection.
