Control.ID Property
Assembly: System.Web (in system.web.dll)
Setting this property on a server control provides you with programmatic access to the server control's properties, events, and methods. This property can be set by Web developers by declaring an ID attribute in the opening tag of an ASP.NET server control.
If this property is not specified for a server control, either declaratively or programmatically, you can obtain a reference to the control through its parent control's Controls property.
