Re: Bug for personalized propertygrid in mono

I am pretty sure that this is a bug in the propertygrid control you are
using. It overrides PropertyGrid.SelectedObject and wraps the object in a
custom one to filter the properties. However it keeps settings the
base.SelectedObject with the same object. The PropertyGrid will not refresh
unless you are setting a different object and I think we have unit tests for
that and that this is the behavior both on MS.NET and Mono. And this comment
confirms what I think -
http://www.codeproject.com/KB/cs/FilteredPropertyGrid.aspx?msg=1422328#xx1422328xx

So you can fix this by changing the source code to set SelectedObject to
null before setting it with the wrapper object to force a reset. Also just
so you know you can also filter the objects properties by using the
BrowsableAttribute and also by implementing the ICustomTypeDescriptor
interface.
