New Post: Populate Select types combo in CollectionEditor with NewItemTypes

I have just returned to this thread and have overridden the ToString method of my Person class
In VB:

    Public Overrides Function ToString() As String
        Return Convert.ToString("mystring") 
    End Function

Where though would I then call this Function. Currently it never gets triggered and therefore my list box does not update with mystring.

Any help much appreciated!
