Przykłady

Ten przykład zastępuje OnAppendToParentBuilder metodę, aby sprawdzić ControlType Właściwość w celu określenia typu formantu, do którego jest stosowany ten Konstruktor.This example overrides the OnAppendToParentBuilder method to check the ControlType property to determine what type of control this builder is applied to. Jeśli jest CustomTextBox , Konstruktor sprawdza, czy wartość HasAspCode właściwości jest uwzględniona w kontrolce.If it is a CustomTextBox, the builder checks whether the value of the HasAspCode property is included in the control. Jeśli tak, wyjątek jest zgłaszany, jeśli nie HasBody jest wywoływana metoda.If so, an exception is thrown, if not the HasBody method is called.
