Did the ExpandableFieldRecordPresenter change between 2009.1 and 2009.2. I have been using a custom ExpandableFieldRecordPresenter Style in all my grids to improve the UI and categorize parts of the grid and it doesnt work in 2009.2.
It sounds like this is the same as the one of the breaking changes in 9.2 regarding the FieldLaouts - You can read more about this in our help here:

Thanks, I followed the suggestion to set the UseNestedPanels to true in the GridViewSettings and all my presentation is back. I love easy fixes especially in the world of wpf.
