New Post: Populate Select types combo in CollectionEditor with NewItemTypes

Is it possible to update what is displayed in the List Box when an associated property is changed.

For instance if in the above code I had instead:

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

and I uncomment the ToString call in the Set of LWEmissivityOut,


I want the List Box to update with the value held in myLWEmissivityOut.

Do I need to force the ListBox to redraw somehow?

Thanks.
