Voorbeelden

In het volgende codevoorbeeld wordt een formulier gemaakt dat een ListView besturingselement bevat dat items handmatig sorteert wanneer op een kolom in het ListView besturingselement wordt geklikt. In het voorbeeld wordt een klasse gedefinieerd ListViewItemComparer die de System.Collections.IComparer interface implementeert waarmee de ListViewItem vergelijking wordt uitgevoerd. In het voorbeeld wordt een exemplaar gemaakt van ListViewItemComparer en wordt deze gebruikt om de ListViewItemSorter eigenschap van het ListView besturingselement in te stellen. De Sort methode-aanroep in de ColumnClick gebeurtenis-handler gebruikt de methoden die zijn ListViewItemComparer gedefinieerd om het soort items uit te voeren, op basis van de kolom waarop wordt geklikt.

Opmerkingen

U kunt deze versie van de Add methode gebruiken om een bestaande ColumnHeader aan de verzameling toe te voegen. Als u een nieuwe ColumnHeader wilt maken op het moment dat u deze aan de verzameling toevoegt, kunt u de andere versie van de Add methode gebruiken.

Wanneer kolomkoppen worden toegevoegd, worden ze toegevoegd aan het einde van de verzameling. Als u een kolomkop wilt invoegen in de verzameling op een specifieke positie, gebruikt u de Insert methode. Gebruik de AddRange methode om een set kolomkoppen toe te voegen aan de verzameling in één bewerking.

Voorbeelden

In het volgende codevoorbeeld wordt een ListView besturingselement gemaakt met drie ListViewItem opgegeven objecten en drie ListViewItem.ListViewSubItem objecten die voor elk item zijn opgegeven. In het voorbeeld worden ook objecten gemaakt ColumnHeader om de subitems weer te geven in de detailweergave. Er worden ook twee ImageList objecten gemaakt in het codevoorbeeld om afbeeldingen voor de ListViewItem objecten te bieden. Deze ImageList objecten worden toegevoegd aan de LargeImageList en SmallImageList eigenschappen. In het voorbeeld worden de volgende eigenschappen gebruikt bij het maken van het ListView besturingselement:

• View

• LabelEdit

• AllowColumnReorder

• CheckBoxes

• FullRowSelect

• GridLines

• Sorting

Voor dit voorbeeld moet u de code hebben toegevoegd aan een Form en de methode aanroepen die in het voorbeeld is gemaakt vanuit de constructor of een andere methode op het formulier. Het voorbeeld vereist ook dat installatiekopieën met de naam MySmallImage1, MySmallImage2en MyLargeImage1MyLargeImage2 zich bevinden in de hoofdmap van station C.

Opmerkingen

U kunt deze versie van de Add methode gebruiken om een nieuwe ColumnHeader te maken die u aan de verzameling kunt toevoegen. De tekst van het nieuwe ColumnHeader toegevoegd aan het besturingselement is gebaseerd op de text parameter. Met deze versie van de Add methode kunt u ook de breedte van de kolom en de uitlijning van tekst in de kolomkop opgeven. Als u een bestaande ColumnHeader verzameling wilt toevoegen, gebruikt u de versie van de Add methode die een ColumnHeader parameter als parameter accepteert.

Wanneer kolomkoppen worden toegevoegd, worden ze toegevoegd aan het einde van de verzameling. Als u een kolomkop wilt invoegen in de verzameling op een specifieke positie, gebruikt u de Insert methode. Gebruik de AddRange methode om een set kolomkoppen toe te voegen aan de verzameling in één bewerking.
