Set the stringformat of a datetime object in code behind.

I have the following code I worked on as an example of creating a binding dynamically for a GridView based on the object(s) that populate the ItemsSource.

    Private Sub SetUpTheColumns(firstObject As Object)
        Dim theClassProperties As PropertyInfo() = firstObject.GetType().GetProperties()
        Dim gv As GridView = theListView.View
        For Each pi As PropertyInfo In theClassProperties
            Dim columnName As String = pi.Name
            Dim grv As New GridViewColumn With {.Header = columnName}
            If pi.PropertyType Is GetType(DateTime) Then
                Dim i As Integer = 1
                Dim bnd As New Binding(columnName) With {.StringFormat = "{}{0:MM/dd/yyyy}"}
                'bnd.StringFormat = "{MM/dd/yyyy}"
                grv.DisplayMemberBinding = bnd
            Else
                grv.DisplayMemberBinding = New Binding(columnName)
            End If
            grv.DisplayMemberBinding = New Binding(columnName)
            gv.Columns.Add(grv)
        Next
        theListView.View = gv
    End Sub
End Class

The problem is with the StringFormat.  Nothing I put in takes.  I have looked at the binding using Snoop and there is no StringFormat for that column binding.  Everything else works great but the stringformat.
