	Membername	Beschreibung
	DropDown	Der Textbereich ist editierbar. Der Benutzer muss auf die Pfeilschaltfläche klicken, um den Listenbereich anzuzeigen. Dies ist das Standardformat.
	DropDownList	Der Benutzer kann den Textbereich nicht direkt bearbeiten. Der Benutzer muss auf die Pfeilschaltfläche klicken, um den Listenbereich anzuzeigen. Die Liste wird nur angezeigt, wenn AutoCompleteMode Suggest oder SuggestAppend ist.
	Simple	Der Textbereich ist editierbar. Der Listenbereich ist immer sichtbar.

Hinweise

Die DropDownStyle-Eigenschaft bestimmt, ob der Benutzer einen neuen Wert in den Textbereich eingeben kann und ob der Listenbereich immer angezeigt wird.

Hinweis zu Windows Mobile für Pocket PC, Windows Mobile für Smartphone, Windows CE: Die Standardart ist DropDownList.

Beispiel

Im folgenden Beispielcode wird die Initialisierung eines ComboBox-Steuerelements durch Festlegen der ComboBox.DropDownStyle-Eigenschaft auf einen ComboBoxStyle-Wert festgelegt.
