Hi Dave,
I do not quite understand your problem, if you have time, I'd like to see
your mocking up.
Thanks

| Dear Jeffery,
| This does not appear to be the problem. The actual data for the
| TypeConverter is held by a separate class that has a static dataset as
| property. I know the dataset is being updated properly. My actual usage
is
| scheduler. The form in question holds 2 property grids, represent a 2 day
| span. The selected object has 24 properties (the hours of the day) that
use
| the my TypeConverter. When I load an object into each of the property
grid,
| I know that the constructor of the typeconverter fires 24 times. Nothing
I
| do can get the constructor to refire. This is why I think the initiation
| process is handled by private static methods that somehow access
information
| about a class. It also appears that this information is stored in some
sort
| of collection and is never updated. If you like, I can do a mock up of the
| code to illustrate the problem.
