'Declaration
Public Overridable ReadOnly Property Rows As HtmlTableRowCollection
'Usage
Dim instance As HtmlTable
Dim value As HtmlTableRowCollection
value = instance.Rows
public virtual HtmlTableRowCollection Rows { get; }
public:
virtual property HtmlTableRowCollection^ Rows {
HtmlTableRowCollection^ get ();
}
/** @property */
public HtmlTableRowCollection get_Rows ()
public function get Rows () : HtmlTableRowCollection
Eigenschaftenwert
Eine HtmlTableRowCollection, die alle Zeilen im HtmlTable-Steuerelement enthält.
Hinweise
Mit der Rows-Auflistung können Sie programmgesteuert auf die Zeilen im HtmlTable-Steuerelement zugreifen. Sie können der Auflistung programmgesteuert Zeilen hinzufügen sowie Zeilen programmgesteuert in die Auflistung einfügen und aus dieser entfernen.
Hinweis
Wenn keine <tr>-Elemente im HtmlTable-Steuerelement aufgelistet sind, wird ein leeres HtmlTableRowCollection-Objekt zurückgegeben.
Beispiel
Im folgenden Codebeispiel wird veranschaulicht, wie dem HtmlTable-Steuerelement mit der Rows-Auflistung programmgesteuert eine Zeile hinzugefügt wird.
