DataBinding.PropertyName-Eigenschaft

Ruft den Namen der ASP.NET-Serversteuerelementeigenschaft ab, für die eine Datenbindung durchgeführt werden soll.

Namespace: System.Web.UI
Assembly: System.Web (in system.web.dll)

Syntax

'Declaration
Public ReadOnly Property PropertyName As String
'Usage
Dim instance As DataBinding
Dim value As String

value = instance.PropertyName

public string PropertyName { get; }

public:
property String^ PropertyName {
    String^ get ();
}

/** @property */
public String get_PropertyName ()

public function get PropertyName () : String

Eigenschaftenwert

Die Eigenschaft, an die Daten gebunden werden sollen.

Beispiel

Im folgenden Codebeispiel werden die drei Variablen dataBindingOutput1, dataBindingOutput2 und dataBindingOutput3 definiert, die auf die verschiedenen Eigenschaften eines DataBinding-Objekts mit dem Namen myDataBinding2 zugreifen. Anschließend wird der Wert der PropertyName-Eigenschaft zu dataBindingOutput1 zugewiesen, dieses mit der Zeichenfolge "The property name is " verkettet und der Wert in eine Datei geschrieben.
