Thanks that seems to be working, I didn't realize one could override a
property!
In case someone is looking for something similar this is how my class
structure now looks like.
generated class:
Private _description As String
<[Property]("description")> _
Public Overridable Property description() As String
Get
Return _description
End Get
Set(ByVal value As String)
value = PropertyModify("description", value)
If _description <> value Then
_description = value
PropertyHasChanged("description")
End If
End Set
End Property
inherited from generated class:
<ValidateIsUnique()> _
Overrides Property Description() As String
Get
Return MyBase.description
End Get
Set(ByVal value As String)
MyBase.description = value
End Set
End Property
I don't seem to need IsOverride since I'm not override an attribute
just adding one to a property.
