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.
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.
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:
