Příklady

Následující příklad kódu vytvoří formulář, který obsahuje ovládací prvek ListView , který ručně seřadí položky při kliknutí na sloupec v ovládacím ListView prvku. Příklad definuje třídu s názvem ListViewItemComparer , která implementuje System.Collections.IComparer rozhraní, které provádí ListViewItem porovnání. Příklad vytvoří instanci ListViewItemComparer a použije ji k nastavení ListViewItemSorter vlastnosti ListView ovládacího prvku. Volání Sort metody v obslužné rutině ColumnClick události používá metody definované v ListViewItemComparer k provedení řazení položek na základě sloupce, který je klikaný.

Poznámky

Tuto verzi Add metody můžete použít k přidání existující ColumnHeader do kolekce. Pokud chcete vytvořit novou ColumnHeader v okamžiku, kdy ho přidáte do kolekce, můžete použít jinou verzi Add metody.

Při přidání záhlaví sloupců se přidají na konec kolekce. Pokud chcete vložit záhlaví sloupce do kolekce na konkrétní pozici, použijte metodu Insert . Pokud chcete přidat sadu záhlaví sloupců do kolekce v jedné operaci, použijte metodu AddRange .

Příklady

Následující příklad kódu vytvoří ovládací prvek ListView se třemi ListViewItem zadanými objekty a třemi ListViewItem.ListViewSubItem objekty zadanými pro každou položku. Příklad také vytvoří ColumnHeader objekty pro zobrazení dílčích položek v zobrazení podrobností. V příkladu kódu jsou také vytvořeny dva ImageList objekty, které poskytují obrázky pro ListViewItem objekty. Tyto ImageList objekty se přidají do LargeImageList vlastností a SmallImageList . V příkladu se při vytváření ListView ovládacího prvku používají následující vlastnosti:

• View

• LabelEdit

• AllowColumnReorder

• CheckBoxes

• FullRowSelect

• GridLines

• Sorting

Tento příklad vyžaduje, abyste přidali kód do Form a volali metodu vytvořenou v příkladu z konstruktoru nebo jiné metody ve formuláři. Příklad také vyžaduje, aby image s názvem MySmallImage1, MyLargeImage1MySmallImage2, a MyLargeImage2 byly umístěny v kořenovém adresáři jednotky C.

Poznámky

Tuto verzi Add metody můžete použít k vytvoření nové ColumnHeader , kterou chcete přidat do kolekce. Text nového ColumnHeader přidaného do ovládacího prvku je založen na parametru text . Tato verze Add metody také umožňuje určit šířku sloupce a zarovnání textu v záhlaví sloupce. Pokud máte existující ColumnHeader objekt, který chcete přidat do kolekce, použijte verzi Add metody, která přijímá ColumnHeader parametr.

Při přidání záhlaví sloupců se přidají na konec kolekce. Pokud chcete vložit záhlaví sloupce do kolekce na konkrétní pozici, použijte metodu Insert . Pokud chcete přidat sadu záhlaví sloupců do kolekce v jedné operaci, použijte metodu AddRange .
