Örnekler

Aşağıdaki kod örneği, özel bir Web Bölümleri denetiminin ve ZoneIndex özelliklerine Zone nasıl erişeceklerini gösterir. Bu örnekte, TextDisplayWebPartsınıfa genel bakışın Örnek bölümünde oluşturulan özel bir denetimin WebPart kullanıldığı varsayılır.

Kod örneği, kullanıcıların Web Bölümleri sayfasındaki görüntü modlarını değiştirmesine olanak tanıyan özel bir kullanıcı denetimi içerir. Kullanıcı denetimine, kullanıcı denetimini barındıran Web sayfasının üst kısmına yakın bir Register yönerge yoluyla başvurulur. Bu kullanıcı denetimini oluşturma ve görüntüleme modlarıyla çalışma hakkında ayrıntılı bir açıklama için bkz . İzlenecek Yol: Özel Web Sunucusu Denetimi Geliştirme ve Kullanma.

Kod örneğinin ikinci bölümü Web sayfasıdır. Sayfada her biri bir Web Bölümü bölgesini temsil eden iki <asp:webpartzone> öğe vardır. İlk bölge, bir bölgede olduğundan çalışma zamanında denetim WebPart gibi davranan standart Calendar bir denetim içerir. İkinci bölge denetimi içerir TextDisplayWebPart . Kullanıcı Bölge Bilgileri düğmesine tıkladığında denetim, Label1 denetimin özelliğinin ZoneIndex değerlerini ve ID denetimin bulunduğu bölgenin özelliğini görüntüler.

Açıklamalar

Web Bölümleri denetim kümesinin mimarisinde, denetimler yalnızca bölgelerin içinde çalıştıklarında Web Bölümleri işlevselliğine WebPartZoneBase sahip olabilir. Web sayfalarında kullanılacak standart WebPartZoneBase bölge denetimdir WebPartZone . Son kullanıcılar Web sayfasındaki farklı bölgeler arasında Web Bölümleri denetimlerini taşıyabilse de, denetimin belirli bir örneği aynı anda yalnızca bir bölgede bulunabilir. Web Bölümleri denetimi ve ilişkili WebPartManager denetimi, denetimin Zone şu anda hangi bölgede yer aldığını ve bölgenin hangi ortak düzen ve stil özelliklerinin tüm kapsanan Web Bölümleri denetimleri için geçerli olduğunu izlemek için özelliğini kullanır.
