I am looking at the newest version of the document: TMS TAdvStringGrid Developers Guide.pdf I can not find any information of the event FixedDropDownClick which is copied below. I am also looking for information on the ASG property: FixedDropDownMenu. Is information on these items in a different help file?
void __fastcall TForm1::AdvStringGrid1FixedDropDownClick(TObject *Sender, int ACol,
int ARow, TPopupMenu *&AMenu, bool &KeepFixedCellHighlighted)
