Dynamic PropertyGrid - adding propertytabs

Hello,

I am building a dynamic property grid whereby I populate it with a class using the selectedobject method. The data is initially displayed as read-only, this is determined through the metadata attributes on the properties of the class. This works fine.

However, I want to add a propertytab to my propertygrid to allow the user to enter a "edit" mode, whereby, upon selection, the propertygrid is refreshed with an updateable version of the readonly class. How do I add a bespoke propertytab to my propertygrid?

Any suggestions?

Thanks.
