Question

I have this code in my view page.

<td>
                        Mandate Name:
                    </td>
                    <td>
                        <%= Html.TextBox("MandateName")%>
                    </td>

I wrote MVC2 Validation for this name.

something like this.

//[Validator(typeof(MandateValidator))]
    [MetadataType(typeof(Mandate_Metadata))]
    public partial class Mandate {

        public class Mandate_Metadata
        {
            [StringLength(250, ErrorMessage = "Mandate name cannot exceed 250 characters!")]
            [Required(ErrorMessage = "Mandate Name Required!")]
            public string MandateName { get; set; }

            [StringLength(3000, ErrorMessage = "Description cannot exceed 3000 characters!")]
            public string MandateDescription { get; set; }
        }

    }

but some how my validation is not working on this field could any body help me what’s wrong I am doing here?
thanks

Answer 1

do you have anything like

<%= Html.ValidationMessageFor(model => model.MandateName)%>

in your view?
