ControlCollection Class
Provides a collection container that enables ASP.NET server controls to maintain a list of their child controls.
Assembly: System.Web (in System.Web.dll)
You can access any of the properties and methods of the ControlCollection class through the Control::Controls property. Since the Control class is the base class for all ASP.NET server controls, all server controls inherit this property.
For more information about collections, see Collections and Data Structures.

The following code example overrides the Control::CreateChildControls method to create two controls, both instances of the custom class named ChildControl, which has a string property named Message. When created, the two controls are added to the ControlCollection. The Add method is called on each of these controls to add them to the class that contains this version of Control::CreateChildControls. The ChildControlsCreated property is set to true so that these controls will not be created again unnecessarily.
