how to fix 'The field must be a date' on a datetime property in mvc

Question

public DateTime?          


        

Answer 1

In the model for example:

    [Display(Name = "Insert Start Date")]
    [Required(ErrorMessage = "You must specify the date of the event!")]
    [DataType(DataType.DateTime, ErrorMessage = "Podaj prawidłową datę wydarzenia")]
    [DisplayFormat(DataFormatString = "{0:yyyy-MM-dd HH:mm}", ApplyFormatInEditMode = true)]
    public DateTime StartDate { get; set; }

    [Display(Name = "Insert End Date")]
    [Required(ErrorMessage = "You must specify the date of the event!")]
    [DataType(DataType.DateTime, ErrorMessage = "Podaj prawidłową datę wydarzenia")]
    [DisplayFormat(DataFormatString = "{0:yyyy-MM-dd HH:mm}", ApplyFormatInEditMode = true)]
    public DateTime EndDate { get; set; }
