DataForm Validation

[Lucas]

Hi

I'm trying to get DataForm validation up and running for my WCF Service based application. I'm using item level attribute-based validation according to http://www.telerik.com/help/wpf/raddataform-validation-item-level.html. This is working fine if I add the attributes directly to the DTO classes generated by the Open Access Service Wizard (i.e. directly in Transport.cs).

[DataMember]
[Required]
public virtual string Name {
    get {
        return this._name;
    }
    set {
        if (Name == value)
            return;

        this.OnPropertyChanging("Name");
        this._name = value;
        this.OnPropertyChanged("Name");
    }
}

However, as adding the metadata to Transport.cs is probably not the best idea, i tried to move the metadata to a seperate metadata class and inject it to the DTO via a MetaDataTypeAttribute.

[MetadataTypeAttribute(typeof(EmployeeDto.Metadata))]
public partial class EmployeeDto
{
    internal sealed class Metadata
    {
        private Metadata() {
        }

        [Required]
        public string Name { get; set; }
    }
}

But i couldn't get this to work, the DataForm ignores the metadata while validating. Is there something I've missed or is this fature not supported by RadDataForm?

Hello Lucas,

May I ask you to send us a repro project that we would be able to debug on our side? You can do this via our support ticket system, which also grants 24h priority response.
