Hinweise

Mit den Membern dieser Enumeration wird der Wert der HeaderStyle-Eigenschaft des ListView-Steuerelements festgelegt.

Beispiel

Im folgenden Codebeispiel wird die Verwendung der ColumnHeaderStyle-Enumeration zum Festlegen der ListView.HeaderStyle-Eigenschaft eines ListView-Steuerelements veranschaulicht. Zum Ausführen dieses Beispiels fügen Sie folgenden Code in ein Formular ein, und rufen Sie die InitializeListView-Methode im Konstruktor oder im Load-Ereignishandler des Formulars auf.

' This method adds two columns to the ListView, setting the Text 
' and TextAlign, and Width properties of each ColumnHeader.  The 
' HeaderStyle property is set to NonClickable since the ColumnClick 
' event is not handled.  Finally the method adds ListViewItems and 
' SubItems to each column.
Private Sub InitializeListView()

    End With
