I have the following Model:

public partial class EmployeeInfo
{
    public int EmployeeInfoId { get; set; }
    [DisplayName("DOB")]
    [Required(ErrorMessage = "Birthdate is required. [MM/DD/YYYY]")]
    public DateTime DateOfBirth { get; set; } 
}

This is what I have on my cshtml page:

<div class="form-group row">
    <div class="col-sm-4">
    <label asp-for="DateOfBirth" class="control-label required" style="font-weight:bold;"></label>
    <input class="form-control input-lg" required name=x size=10 maxlength=10 onkeydown="this.value=this.value.replace(/^(\d\d)(\d)$/g,'$1/$2').replace(/^(\d\d\/\d\d)(\d+)$/g,'$1/$2').replace(/[^\d\/]/g,'')" />
    <span asp-validation-for="DateOfBirth" class="text-danger"></span>
</div>

I cannot put type="date" for this field. How can I see the validation error message for date of birth field since I am not putting type="date". I still want to see the error message saying "DOB is required", but I don’t see any message.

Any help will be greatly appreciated.
