Příklady

Následující příklad kódu ukazuje inicializaci ovládacího prvku ListView . Příklad vytvoří ColumnHeader objekty a nastaví vlastnosti a TextAlignWidth záhlaví Textsloupce. Příklad také přidá položky a podřízené položky do ListView. Chcete-li spustit tento příklad, vložte do formuláře následující kód a zavolejte metodu PopulateListView z konstruktoru formuláře nebo Load obslužné rutiny události.

Poznámky

Tuto vlastnost můžete použít k poskytnutí různých nastavení zarovnání textu zobrazeného v jednotlivých ColumnHeaderobjektech .

Poznámka

Z důvodu omezení v podkladovém ovládacím prvku nemá tato vlastnost žádný vliv na první sloupec v ovládacím ListView prvku, který je vždy zarovnán doleva. Chcete-li obejít toto omezení v rozhraní .NET Framework 2.0, můžete zpracovat ListView.DrawColumnHeader událost a malovat záhlaví sloupce sami.
