           Summary: PropertyGrid: TypeConverterAttribute on a property is
                    ignored
           Product: Mono: Class Libraries
           Version: SVN
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: P5 - None

The current code respects the TypeConverterAttribute when applied to a type. 
When applied to a particular property however the attribute is ignored.

Repro is attached, another version of my WinForms PropertyGrid 'many types'
app.  It has three properties of type System.Version, in category "my
Attributes on Properties":
* one property is attribute-less, so is not editable and is just displayed by
ToString fall-back as "X.X.X.X".
* one which has a TypeConverter applied to the property, the t/c can convert
from Version to string as "vX.X.X.X", and thus should be displayed in that
format.
* and finally, one which has a TypeConverter applied to the property which can
convert to and from, and thus should be displayed and editable.  Displayed as
the previous, but editable as "vX.X.X.X" or "X.X.X.X".

That behaves as expected in MSFT.  In Mono all three display as "X.X.X.X" and
are not editable.  Therefore it appears that the attributes are ignored.


I would have guessed that the properties and the converter value were returned
by TypeDescription.GetProperties / PropertyDescriptor.Converter, but those
methods seem to be working properly.  I'll log a new bug with some unit-test to
confirm that.
