Hi kkasunperera,

Here is an example which shows export of the rows of nested grids. However, note that to export a nested grid, it must first be initialized (initrowdetails called), i.e. the parent row should be “expanded”. The rows of the grids are also exported in the order of initialization of their respective grids.
