Thanks much. I tried it (translated to VB since that's what I'm using)
and it worked. So I looked closer to see why my class, which was
roughly equivalent, didn't work. Oddly, it is something I did not
expect.

In VB, I've always used Public variables in classes rather than a
private variable and associated property declaration, unless I needed
greater control over the values coming in or going out. In fact, I
thought that the compiler just converted a public class variable into
a private variable and associated property clauses.

However, a generic collection of this class did not work with
databind:

 Friend Class CaseChoice
   Public ClientLastName As String
   Public ClientFirstName As String
   Public DocketInd As String
   Public DOB As String
 End Class

This class, with one public variable converted into a property, works
with Databind but only the one property shows on the grid:

 Friend Class CaseChoice
   Private _ClientLastName As String
   Public ClientFirstName As String
   Public DocketInd As String
   Public DOB As String
   Property ClientLastName() As String
     Get
       Return _ClientLastName
     End Get
     Set(ByVal value As String)
       _ClientLastName = value
     End Set
   End Property
   Public Sub New(ByVal InCLN As String)
     _ClientLastName = InCLN
   End Sub
 End Class

This class works fine even though some properties are readonly and
others aren't:

 Friend Class CaseChoice
   Private _ClientLastName As String
   Private _ClientFirstName As String
   Private _DocketInd As String
   Private _DOB As String

   Property ClientLastName() As String
     Get
       Return _ClientLastName
     End Get
     Set(ByVal value As String)
       _ClientLastName = value
     End Set
   End Property

   Property ClientFirstName() As String
     Get
       Return _ClientFirstName
     End Get
     Set(ByVal value As String)
       _ClientFirstName = value
     End Set
   End Property

   ReadOnly Property DOB() As String
     Get
       Return _DOB
     End Get
   End Property

   ReadOnly Property DocketInd() As String
     Get
       Return _DocketInd
     End Get
   End Property

   Public Sub New(ByVal InCLN As String, ByVal InCFN As String, ByVal
InDI As String, ByVal InDOB As String)
     _ClientLastName = InCLN
     _ClientFirstName = InCFN
     _DocketInd = InDI
     _DOB = InDOB
   End Sub
 End Class


Very odd. I would thing that functionally a public variable would be
exactly the same as a property. Oh well, something new to look into. I
guess I'll have to look at the IL.
