I've been fighting this for a solid 30 minutes now. When I change the value
of a property outside of the grid, I can't get the grid to change the
display. If I obscure the window behind another window and then return it to
the top, the grid displays the proper value. I call Refresh() on the
PropertyGrid. After that, I've attempted other calls to try to get the
display updated, but all to no avail.  Invalidate() and Update(), even in
combination after Refresh(), don't cause the grid to display the new value.
I'm developing using Managed C++ in VS 2005. Does anybody have any ideas?

Thanks,
Noah
