Dbgrid in multiple-choice state how to determine which lines are selected are there?
GdSelected State can only judge in the currently selected line, can't judge which lines is selected,

Delphi DBGrid lunch does not support multiple,

Multiple-choice, can use third party controls, or inherit a new DBGrid,

For I:=0 to DBGrid1. SelectedRows. Do the Count - 1

DBGrid1. The DataSource. The DataSet. GotoBookmark (Pointer (DBGrid1. SelectedRows. Items [I])); 
ShowMessage (DBGrid1 DataSource. The DataSet. Fields. [0] AsString) are identical. 
end; 
end;

I am not going to take the selected data, I am want to know which lines is selected, and then selected row discoloration

As such, the current line selected will not change color, only the selected guild discoloration
