How to select current row or particular rows programmatically in multiselect mode?

In multiselect mode, normally we hold ctrl key and click the fixed-row (in the most left part of DBGrid) to select rows.

How to select current row or particular rows programmatically in multiselect mode?

By the way, I've tried this code:

MyDBGrid.SelectedRows.CurrentRowSelected:=True;

But the problem is, the fixed-row is not highlighted.

Any Idea?

I just dropped a grid, datasource and TTable on a form and used the DBDemos vendors.db table to illustrate:


procedure TForm1.Button1Click(Sender: TObject);
var bkm: pointer;
begin
  //example to select first, a looked up records and the last
  //record programmatically

  dbgrid1.DataSource.DataSet.DisableControls;
  bkm:= dbgrid1.DataSource.DataSet.GetBookmark;
  dbgrid1.SelectedRows.Clear;
  dbgrid1.DataSource.DataSet.First;
  dbgrid1.SelectedRows.CurrentRowSelected:= true;
  if dbgrid1.DataSource.DataSet.Locate('VendorNo', 3819, [loCaseInsensitive])
  then dbgrid1.SelectedRows.CurrentRowSelected:= true;
  dbgrid1.DataSource.DataSet.Last;
  dbgrid1.SelectedRows.CurrentRowSelected:= true;

  dbgrid1.DataSource.DataSet.GotoBookmark(bkm);
  dbgrid1.DataSource.DataSet.EnableControls;
end;

I think that approach also won't highlight the fixed-row (in the most left part of DBGrid) as when we manually hold ctrl key and click the fixed-row to select rows.

I tested it on my machine and get exact same results as when doing so manually as when doing so programmatically.
