Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

Syntax

'Declaration
Public Sub ResetStyle
'Usage
Dim instance As ListViewSubItem

instance.ResetStyle

public void ResetStyle ()

public:

Mithilfe dieser Methode können die Einstellungen für Schriftart, Vorder- und Hintergrundfarbe des Unterelements zurückgesetzt werden. Wenn die Formate zurückgesetzt werden, werden die Unterelemente mit den Standardeinstellungen für Schriftart und Vorder- sowie -Hintergrundfarbe angezeigt.

Beispiel

Im folgenden Codebeispiel wird veranschaulicht, wie der Stil der Unterelemente eines ListViewItem mithilfe der ListView.TopItem-Eigenschaft und der ResetStyle-Methode neu festgelegt wird. Zum Ausführen des Beispiels fügen Sie folgenden Code in ein Formular ein, das eine Schaltfläche mit dem Namen Button1 enthält, und rufen Sie die InitializeListView-Methode im Konstruktor oder in der Load-Ereignisbehandlungsmethode des Formulars auf.
