ListView.ColumnHeaderCollection.Add Método

public:
 virtual System::Windows::Forms::ColumnHeader ^ Add(System::String ^ text);

public virtual System.Windows.Forms.ColumnHeader Add (string text);

public virtual System.Windows.Forms.ColumnHeader Add (string? text);

abstract member Add : string -> System.Windows.Forms.ColumnHeader
override this.Add : string -> System.Windows.Forms.ColumnHeader

Public Overridable Function Add (text As String) As ColumnHeader

Parâmetros

Retornos

O ColumnHeader com o texto especificado que foi adicionado ao ListView.ColumnHeaderCollection.

Comentários

O cabeçalho da coluna será adicionado ao final da coleção.

public:
 virtual int Add(System::Windows::Forms::ColumnHeader ^ value);

public virtual int Add (System.Windows.Forms.ColumnHeader value);

abstract member Add : System.Windows.Forms.ColumnHeader -> int
override this.Add : System.Windows.Forms.ColumnHeader -> int

Public Overridable Function Add (value As ColumnHeader) As Integer

Parâmetros

Retornos

O índice de base zero na coleção à qual o item foi adicionado.

Exemplos

O exemplo de código a seguir cria um formulário que contém um ListView controle que classifica manualmente os itens quando uma coluna no ListView controle é clicada. O exemplo define uma classe chamada ListViewItemComparer que implementa a System.Collections.IComparer interface que executa a ListViewItem comparação. O exemplo cria uma instância de ListViewItemComparer e a usa para definir a ListViewItemSorter propriedade do ListView controle . A Sort chamada de método no ColumnClick manipulador de eventos usa os métodos definidos em ListViewItemComparer para executar o tipo de itens, com base na coluna clicada.

Comentários

Você pode usar essa versão do Add método para adicionar um existente ColumnHeader à coleção. Se você quiser criar um novo ColumnHeader no momento em que adicioná-lo à coleção, poderá usar a outra versão do Add método .

Quando os cabeçalhos de coluna são adicionados, eles são adicionados ao final da coleção. Para inserir um cabeçalho de coluna na coleção em uma posição específica, use o Insert método . Para adicionar um conjunto de cabeçalhos de coluna à coleção em uma única operação, use o AddRange método .

Exemplos

O exemplo de código a seguir cria um ListView controle com três ListViewItem objetos especificados e três ListViewItem.ListViewSubItem objetos especificados para cada item. O exemplo também cria ColumnHeader objetos para exibir os subitems na exibição de detalhes. Dois ImageList objetos também são criados no exemplo de código para fornecer imagens para os ListViewItem objetos. Esses ImageList objetos são adicionados às LargeImageList propriedades e SmallImageList . O exemplo usa as seguintes propriedades na criação do ListView controle :

• View

• LabelEdit

• AllowColumnReorder

• CheckBoxes

• FullRowSelect

• GridLines

• Sorting

Este exemplo exige que você tenha adicionado o código a um Form e chame o método criado no exemplo do construtor ou outro método no formulário. O exemplo também requer que as imagens chamadas MySmallImage1, MySmallImage2, MyLargeImage1e MyLargeImage2 estejam localizadas no diretório raiz da unidade C.

Comentários

Você pode usar essa versão do Add método para criar um novo ColumnHeader para adicionar à coleção. O texto do novo ColumnHeader adicionado ao controle baseia-se no text parâmetro . Essa versão do Add método também permite que você especifique a largura da coluna e o alinhamento do texto no cabeçalho da coluna. Se você tiver um existente ColumnHeader que deseja adicionar à coleção, use a versão do Add método que aceita um ColumnHeader como parâmetro.

Quando os cabeçalhos de coluna são adicionados, eles são adicionados ao final da coleção. Para inserir um cabeçalho de coluna na coleção em uma posição específica, use o Insert método . Para adicionar um conjunto de cabeçalhos de coluna à coleção em uma única operação, use o AddRange método .
