DropDownListBox
Mit einem DropDownListBox-Oberflächenelement können Sie ein Aufklappmenü realisieren. Aus diesem Aufklappmenü können Sie höchstens einen Eintrag auswählen. Das Oberflächenelement besteht aus einem Textfeld, einer Drucktaste sowie einer Auswahlliste. Wenn die Drucktaste betätigt wird, wird eine Liste aller möglichen Werte angezeigt. Ein bereits ausgewählter Listeneintrag wird im Textfeld dargestellt.
Die DropDownListBox verbindet die Funktionalität der beiden UI-Elemente DropDownByKey und DropDownByIndex indem sie zur Datenbindung sowohl Index Binding über die Eigenschaft itemDataSource und Key Binding über die Eigenschaft selectedKey verwendet. Einen visuellen Unterschied zu den beiden DropDown-Elementen gibt es zunächst nicht (siehe nachfolgende Grafik):
Weitere Informationen finden Sie unter Datenbindung mittels Index und Schlüssel.
