TableCell.CreateControlStyle-Methode
Erstellt eine TableItemStyle-Klasse für das TableCell-Steuerelement.
Namespace: System.Web.UI.WebControls
Assembly: System.Web (in system.web.dll)
Syntax
'Declaration
Protected Overrides Function CreateControlStyle As Style
'Usage
Dim returnValue As Style
returnValue = Me.CreateControlStyle
protected override Style CreateControlStyle ()
protected:
virtual Style^ CreateControlStyle () override
protected Style CreateControlStyle ()
protected override function CreateControlStyle () : Style
Rückgabewert
Eine Style-Klasse, die die TableItemStyle-Klasse für das TableCell-Steuerelement darstellt.
Hinweise
Die von der CreateControlStyle-Methode erstellte TableItemStyle-Klasse wird mit den Eigenschaften Wrap, HorizontalAlign und VerticalAlign verwendet.
Die CreateControlStyle-Methode wird hauptsächlich von Entwicklern von Steuerelementen zum Erweitern der Funktionalität des TableCell-Steuerelements verwendet.
Beispiel
Im folgenden Codebeispiel wird veranschaulicht, wie die CreateControlStyle-Methode in einem benutzerdefinierten Serversteuerelement überschrieben wird, sodass immer eine neue Instanz der TableStyle-Klasse für die TableCell zurückgegeben wird.
