Hi Ivan,

The snippet above will raise INotityPropertyChanged only.

For INotityDataErrorInfo, try: (in your Entity's partial class)

[StringLengthVerifier(MaxValue = 20, MinValue = 6, IsRequired = true, ErrorMessage = "Password Required")]

public string PasswordEX {

get {

return PropertyMetadata.PasswordEX.GetValue(this);

}

set {

PropertyMetadata.PasswordEX.SetValue(this, value);

}

public partial class PropertyMetadata {

public static readonly IbEm.DataEntityProperty PasswordEX = new IbEm.DataEntityProperty("PasswordEX", false, false, IbEm.ConcurrencyStrategy.None, false, null, false);

}

Regards,

Silvio.

Hi Ivan,

try:

public string PasswordEX {

get { return passwordEX; }

set {

passwordEX = value;

OnPropertyChanged(new PropertyChangedEventArgs("PasswordEX"));

}

I'm trying to make my partial class to play nicely with verification engine(see code below).

I'm trying to create new property (PasswordEx) which works.

I need to add verifier to this property. Adding it using attribute. It works. Kind of..

When whole entity validated - it works and I get this field warning, etc.

What I want is INotifyDataErrorInfo to work for this property so user see wrong entry right away...

My guess is that I need to tell VerifierEngine to run verification on this property inside my setter but can't come up with syntax to do that. Or maybe I can do it some other way?

Also, how would I raise INotifyPropertyChanged event from my partial class? Is there any built-in gluing in DevForce?

[MetadataType(typeof(MEMUserMetadata))]
    public partial class User
    {
        private string passwordEx;

        [StringLengthVerifier(MaxValue = 20, MinValue = 6, IsRequired = true, ErrorMessage = "Password Required")]
        public string PasswordEx
        {
            get
            {
                return this.passwordEx;
            }

            set
            {
                this.passwordEx = value;
            }
        }

public string PasswordAgainEx { get; set; }

}
