Exemplos

O exemplo de código a seguir ajusta as bordas de célula de uma DataGridView para que uma borda dupla separe as células internas e a célula de cabeçalho superior esquerdo dos cabeçalhos de linha e coluna. Este exemplo demonstra como substituir os AdjustColumnHeaderBorderStyle AdjustRowHeaderBorderStylemétodos e AdjustCellBorderStyle os métodos e a AdjustedTopLeftHeaderBorderStyle propriedade. Esses membros usam DataGridViewAdvancedBorderStyle objetos para modificar bordas de células individuais.

Comentários

O DataGridView controle permite personalizar totalmente sua aparência, incluindo as bordas das células e cabeçalhos. O DataGridView tem CellBorderStylee ColumnHeadersBorderStyleas RowHeadersBorderStyle propriedades que permitem definir a aparência da borda da célula. No entanto, se você precisar personalizar ainda mais as bordas, a DataGridViewAdvancedBorderStyle classe permitirá que você defina o estilo da borda nos lados individuais das células. As Leftpropriedades DataGridViewAdvancedBorderStyle de representar Right Top Bottom a borda esquerda, direita, superior e inferior de uma célula, respectivamente. Você pode definir essas propriedades nas AdvancedCellBorderStylepropriedades , AdvancedColumnHeadersBorderStyle AdvancedRowHeadersBorderStyle da DataGridView para produzir várias aparências para as bordas entre as células.
