Is it possible to create a custom field in a BO, that is not part of the underlying DataSource,  that I can bind to?  I tried adding the following custom field to my BO.

Private mVerifyPassword As String = ""

<Browsable(False), _

BusinessFieldDisplayInEditor(), _

Description("Verify Password"), _

DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)> _

Public Property UserCF_VerifyPassword() As System.String

   Get

     Return mVerifyPassword

   End Get

   Set(ByVal value As System.String)

      If mVerifyPassword = value.Trim Then Exit Property

      mVerifyPassword = value.Trim

Me.OnFieldPropertyChanged(Me, _

 New UserFieldChangedEventArgsmVerifyPassword))

   End Set

End Property

I can bind to it in the designer but when I go to run the program I get the following error:

BusinessLayerException

                An error occurred while refreshing the data from field 'UserBO.UserCF_VerifyPassword' to property 'Text' on control 'txtVerifyPassword.'  Are you missing FieldPropertyDescriptor for a custom property?

ArgumentException

                Cannot bind to the property or column UserCF_VerifyPassword on the DataSource.

Parameter name: dataMember
