 property Type ^ ControlType { Type ^ get(); };
public Type ControlType { get; }
member this.ControlType : Type
Public ReadOnly Property ControlType As Type

Özellik Değeri

Type Denetim türünü temsil eden bir.

Örnekler

Aşağıdaki kod örneği, hem ConsumerConnectionPoint hem de ProviderConnectionPoint nesnelerinde özelliğinin ControlType kullanımını gösterir. Bu kod örneği yalnızca özelliğine erişecek kodu içeren Web sayfasını gösterir; örneği çalıştırmak için gereken kodun tamamı için, sınıfa genel bakışın ConnectionPoint Örnek bölümüne bakın.

Web sayfasının yöntemindeki Button2_Click kod, bağlantı noktası nesnelerinin her birinde özelliğine erişir ControlType ve her değeri bir etikete yazar. Sayfa bir tarayıcıya yüklendikten sonra Bağlantı Noktası Ayrıntıları düğmesine tıklayarak kodu yürütebilirsiniz.

Açıklamalar

özelliğinin ControlType değeri genellikle türüdür WebPart . Ancak, her tür kullanıcı denetimi veya sunucu denetimi düzgün bir şekilde etkinleştirilip bir WebPartZoneBase bölgeye yerleştirildiğinde bağlantılara katılabileceğinden, ControlType özellik bu diğer sunucu denetim türlerinden birini de döndürebilir.

Denetim olmayan WebPart sunucu denetimleri bir WebPartZoneBase bölgeye yerleştirildiğinde, denetim olarak WebPart çalışabilmeleri ve bağlantılara katılabilmeleri için çalışma zamanında bir GenericWebPart nesneyle sarmalanıyorlar. Ancak bu tür denetimler bağlantılara dahil olduğunda, ControlType özellik değeri türü döndürmez GenericWebPart ; nesnenin GenericWebPart sunucu veya kullanıcı denetiminin türü olan alt denetiminin türünü döndürür.
