Definição
Importante
Algumas informações se referem a produtos de pré-lançamento que podem ser substancialmente modificados antes do lançamento. A Microsoft não oferece garantias, expressas ou implícitas, das informações aqui fornecidas.
Obtém ou define um valor que indica se a coluna que contém cabeçalhos de linha é exibida.
public:
property bool RowHeadersVisible { bool get(); void set(bool value); };public bool RowHeadersVisible { get; set; }member this.RowHeadersVisible : bool with get, setPublic Property RowHeadersVisible As BooleanValor da propriedade
true se a coluna que contém cabeçalhos de linha for exibida; caso contrário, false. O padrão é true.
Exceções
O valor especificado ao definir essa propriedade é false e a AutoSizeRowsMode propriedade é definida como AllHeaders ou DisplayedHeaders.
Exemplos
O exemplo de código a seguir demonstra como definir as ColumnHeadersDefaultCellStylepropriedades, , AutoSizeRowsMode, ColumnHeadersBorderStyle, GridColorCellBorderStyle, BackgroundColor, RowHeadersVisible, ColumnCountSelectionModee MultiSelect propriedades. Além disso, o exemplo de código demonstra como definir as propriedades e DataGridViewColumn.DefaultCellStyle as DataGridViewColumn.Name propriedades. Para executar este exemplo, cole o código em um formulário que contém um DataGridView nome dataGridView1e chame o SetUpDataGridView método do construtor ou Load manipulador de eventos do formulário. Verifique se todos os eventos estão associados aos manipuladores de eventos.
