Comentários
A DataGridViewImageColumn classe é um tipo especializado da DataGridViewColumn classe usada para hospedar logicamente células que exibem imagens. Um DataGridViewImageColumn tem um associado DataGridViewImageCell em cada DataGridViewRow que o intersecciona. Cada célula é capaz de conter um Image ou um Icon, dependendo do valor da DataGridViewImageCell.ValueIsIcon propriedade. Exibir ícones é útil para acomodar imagens com transparência.
Por padrão, as células vazias exibem um gráfico de erro padrão. Para impedir que esse gráfico apareça para valores de célula iguais a null ou DBNull.Value, defina a DataGridViewCellStyle.NullValue propriedade do objeto de estilo de célula retornado pela DefaultCellStyle propriedade como null antes de adicionar linhas ao controle. No entanto, isso não afeta a linha de novos registros. Para impedir que o gráfico de erro apareça na linha para novos registros quando o valor da propriedade de controle AllowUserToAddRows for , você também deve definir explicitamente o valor null da célula como em um manipulador para o evento de controle RowsAdded ou definir a propriedade de coluna CellTemplate como uma instância de um DataGridViewImageCelltipo derivado de com uma propriedade substituída DefaultNewRowValue que retorna nulltrue.
O modo de classificação padrão para esse tipo de coluna é NotSortable.
Notas aos Herdeiros
Ao derivar de DataGridViewImageColumn e adicionar novas propriedades à classe derivada, substitua o Clone() método para copiar as novas propriedades durante as operações de clonagem. Você também deve chamar o método da Clone() classe base para que as propriedades da classe base sejam copiadas para a nova célula.
