Hello Edotom,

it’s definitively not a bug. Expanding of the subgrid is not the same as selection. Many subgrid can be expanded, but no row can be selected or the selected row can have no relation to the selected row.

You don’t describe what exactly you try to do. The most scenarios can be implemented by usage subgrid callbacks (see the documentation). If you need to test whether some row is expanded (the “+” icon from the subgrid column was clicked before) then you can first get

which contains “+” or “-” icon (the is the direct child having class “ui-sgcollapsed”) and then you can test whether the cell have “sgexpanded” class or “sgcollapsed” class.

Best regards
Oleg
