Classe MonthCalendar
Representa um controle do Windows que permite que o usuário selecione uma data usando um painel visual de calendário mensal.
Assembly: System.Windows.Forms (em System.Windows.Forms.dll)
The MonthCalendar controle permite que o usuário selecionar uma data usando uma exibição visual. Você pode limitar a data e horas que podem ser selecionadas, definindo o MinDate e MaxDate Propriedades.
Você pode alterar a aparência da parte do controle pelo calendário configuração o ForeColor, Font, TitleBackColor, TitleForeColor, TrailingForeColor, e BackColor Propriedades.
The MonthCalendar controle é desenhado pelo sistema operacional, portanto, o Paint evento nunca é gerado. Se você precisar fornecer uma aparência personalizada à MonthCalendar controle, você deve substituir o OnPrint método, telefonar implementação base do OnPrinte, em seguida, executar pintura personalizada.
Se precisar de uma seleção limitada a apenas uma data e formatação de data personalizado, você poderá considerar o uso de um DateTimePicker controlar em vez de um MonthCalendar. Usando o DateTimePicker elimina a maior parte da necessidade de validação de valores de data/time.
Para obter mais informações sobre o mês controles de calendário, consulte "Controles de calendário do mês" na documentação do plataforma SDK emhttp://msdn.Microsoft.com.
Observação:

|
Usando o MonthCalendar com estilos visuais ativados fará com que um intervalo de seleção para o MonthCalendar controle não pintar corretamente e data de hoje estejam contidas em um quadrado se ShowTodayCircle é conjunto para true. |
O exemplo de código a seguir exibe um formulário que contém um MonthCalendar controle que exibe um ano do calendário. O exemplo demonstra a configuração de BackColor, ForeColor, TitleBackColor, TitleForeColor, CalendarDimensions, e TrailingForeColor propriedades para personalizar a aparência do controle de calendário. Outras propriedades, sistema autônomo AnnuallyBoldedDates, BoldedDates, e MonthlyBoldedDates são conjunto personalizar quais datas estão em negrito. O exemplo também define o FirstDayOfWeek, MaxDate, MinDate, e MaxSelectionCount propriedades para alterar o formato de calendário. The DateSelected e DateChanged eventos também são processados e seu status é exibido no formulário.
