Notifies the control that an element was parsed and adds the element to the Label control.
Assembly: System.Web (in System.Web.dll)
The method is used primarily by control developers when deriving a custom control from the Label class.
If the input object is a LiteralControl, and the Label control has no child controls, the input object is used to set the Text property of the Label control. Otherwise, the AddParsedSubObject method of the base Control class is called and the specified object is added to the Controls collection.
The following code example demonstrates how to override the method in a custom Label server control so that it always sets the text property to the parsed object's text property, if the parsed object is a Literal, and to an empty string otherwise.
