Hinweise
Das SqlDataSource-Datenquellen-Steuerelement stellt Daten in einer SQL-basierten relationalen Datenbank für datengebundene Steuerelemente dar. Das SqlDataSource-Steuerelement kann in Verbindung mit einem datengebundenen Steuerelement verwendet werden, um Daten aus einer relationalen Datenbank abzurufen und Daten auf einer Webseite mit wenig oder gar keinem Code anzuzeigen, zu bearbeiten oder zu sortieren.
Weitere Informationen zur Verwendung des SqlDataSource-Steuerelements finden Sie unter Übersicht über das SqlDataSource-Webserversteuerelement.
Beispiel
Im folgenden Codebeispiel wird die deklarative Verwendung eines SqlDataSource-Steuerelements veranschaulicht, um Daten von Microsoft SQL Server abzurufen und diese in einem GridView-Steuerelement anzuzeigen.
