Expanding a category in the tool part editor

[greg]

Hi all,

I'm in the process of migrating our old SharePoint web parts to use the new
web part framework of ASP.NET 2.0.

To expand a specified category of the tool part editor I had to create a
CustomPropertyToolPart and call its Expand method passing the category that
I was interested in.

Does anybody knows how to do that in the ASP.NET 2.0 web part framework?

Thanks in advance,
Greg.
