How can I expand the grid inside another grid.

Hi

We are using activewidgets 2.0.1 for presentation.We have a fund of fund application in which we are opening a fund related information.What I want is that when I click on that fund , the grid should expand and should also show fund underlying funds.

How should I implement this in AW 2.0.1?

How can I merge the two xml data in single xml and show this to user.

Thanks
