model state validation for DateTime Input

[Bina]

I am using the Kendo DateInput inside my razor views as below

 <span>Date of Birth</span>
    @(Html.Kendo().DateInput().Name("Patient.Dob").Format("dd-MMM-yyyy").Min(new DateTime(1900, 1, 1))
             .Max(DateTime.Today).Messages(m => m.Year("yyyy").Day("dd").Month("mmm")))
 
When the date of birth is not entered, the model state validation fails as it tries to validate the placeholder value - ("dd-MMM-yyyy")

How can i specify the placeholder, such that it does not do model state validation

Hi Bina,

You should either make the DateTime filed nullable or set the Required attribute in the model for that field:

[DisplayName("Last supply")]
[DataType(DataType.Date)]
public DateTime? Dob
{
    get;
    set;
}

or

[Required]
[DisplayName("Last supply")]
[DataType(DataType.Date)]
public DateTime Dob
{
    get;
    set;
}

Hope this helps.

Thanks for your response.

I have already set the DateTime field as nullable as below

        [Display(Name = "Date of Birth")]
        [Column("DOB", TypeName = "date")]
        [DisplayFormat(DataFormatString = "{0:dd-MMM-yyyy}", ApplyFormatInEditMode = true)]
        public DateTime? Dob { get; set; }

 

The problem is that, during the postback, the raw value available in the model is dd-mmm-yyyy and hence the modelState.Valid returns false in the Controller method.

Note: the model holds the value null. But the raw value is dd-mmm-yyyy. model validation error states that the format dd-mmm-yyyy is not a valid date.

Hi Bina,

Could you please open a regular support ticket and attach a sample, runnable project replicating the issue, because on my local tests I was not able to replicate the issue in question?

I'm issuing the same problem. What might cause the problem?

Hello,

We would need a sample runnable sample project to investigate it locally. Since you are not able to attach projects in the forum I would suggest to open a support ticket and attach the project in the ticket.
