I am trying to  add an xls datasheet to a AdvStringGrid with existing data.  Every import just wipes out existing data.  Tried setting GridStartRow to end of existing data.  Any suggestions?


I thought this should be possible, but I checked and we only provide the option of "not clearing" when exporting, but not when importing. By design, an import will wipe out all existing data.

I am not sure if we can efficiently do an export without clearing before, but I will investigate and let you know.


We can confirm an option is added with which you'll be able to control the clearing on import in the next  update.
