Vorgehensweise: Aktivieren der Tile-Ansicht in einem ListView-Steuerelement von Windows Forms

  • Artikel

Mit dem Feature für "Ansicht 'Nebeneinander'" des ListView-Steuerelements können Sie eine visuelle Balance zwischen grafischen und textbasierten Daten herstellen. Die textbasierten Daten, die für ein Element in der Ansicht "Nebeneinander" angezeigt werden, sind die gleichen wie die Spalteninformationen, die für die Detailansicht definiert wurden. Die Ansicht "Nebeneinander" funktioniert in Kombination mit den Features "Gruppieren" oder "Einfügemarke" des ListView-Steuerelements.

Für die Ansicht "Nebeneinander" wird ein 32 x 32 Pixel großes Symbol mit mehreren Textzeilen verwendet, wie in den folgenden Abbildungen dargestellt.

Tile View in a ListView Control

Um die Ansicht "Nebeneinander" zu aktivieren, legen Sie die View-Eigenschaft auf Tile fest. Sie können die Größe der Kacheln anpassen, indem Sie die TileSize-Eigenschaft festlegen, und Sie können die Anzahl der angezeigten Textzeilen festlegen, indem Sie die Columns-Auflistung anpassen.

So legen Sie die Ansicht "Nebeneinander" programmgesteuert fest

  1. Verwenden Sie die View-Enumeration des ListView-Steuerelements.

    ListView1.View = View.Tile  

    listView1.View = View.Tile;

Beispiel

Die folgenden vollständigen Codebeispiele zeigen die Ansicht "Nebeneinander" mit Kacheln, die so geändert wurden, dass drei Textzeilen angezeigt werden. Die Kachelgröße wurde angepasst, um Zeilenumbrüche zu vermeiden.

Kompilieren des Codes

Für dieses Beispiel benötigen Sie Folgendes:

  • Verweise auf die Assemblys "System" und "System.Windows.Forms".

  • Eine Symboldatei mit Namen "book.ico", die sich im selben Verzeichnis befinden wie die ausführbare Datei.
