Datatype.Date 如何将最短日期设置为今天?
Datatype.Date how to set minimum date to Today?
我使用 MVC5 创建了一个日期选择器 DataType.Date:
[DataType(DataType.Date)]
public DateTime ArrivalDate { get; set; }
如何将最短可用日期设置为今天并禁用所有过去的日期?
或者,是否有禁用自定义日期范围的选项?
我尝试使用 this answer, but with that I get the following error: named parameter type constraints
创建自定义 DateRangeValidator
这是我的日期范围验证器:
public DateTime FirstDate = DateTime.Today.Date;
//public DateTime SecondDate { get; set; }
protected override ValidationResult IsValid(DateTime date, ValidationContext validationContext)
{
// your validation logic
if (date >= DbFunctions.TruncateTime(FirstDate))
{
return ValidationResult.Success;
}
else
{
return new ValidationResult("Date is not valid.");
}
}
尝试使用您自己的逻辑构建自定义验证属性:
public sealed class PresentOrFutureDateAttribute: ValidationAttribute
{
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
// your validation logic
if (Convert.ToDateTime(value) >= DateTime.Today)
{
return ValidationResult.Success;
}
else
{
return new ValidationResult("Past date not allowed.");
}
}
}
