Good day.

I need to implement feature like this. Just imagine.
You have a grid on your form. Than you click on field title and choose menu «Select similar». The grid looks what is the value in the active cell and must select all rows which have the same value in that field (loop by column).

After that if you press key arrows (change active row) selected items don't lose their states.

Here is the code to see that bug.

CODE

Grid.BeginUpdate;
for j := 0 to Grid.RowCount - 1 do begin
Grid.Selected[j] := true;
end;
Grid.EndUpdate;
Grid.SetFocus;

How to solve this?

Hello,

Please add one new procedure in NxCustomGridControl.pas (inside public section):

CODE

procedure TNxCustomGridControl.SetMultiSelected;
begin
  Include(FGridState, gtMultiSelect);
end;

Then, use next code:

CODE

procedure TForm1.Button1Click(Sender: TObject);
var
  j: Integer;
begin
  Grid.BeginUpdate;
  Grid.SelectedRow := 0; // <--- SelectedRow is -1 by default.
  for j := 0 to Grid.RowCount - 1 do begin
    Grid.Selected[j] := true;
  end;
  Grid.EndUpdate;
  Grid.SetFocus;
  Grid.SetMultiSelected;
end;

I hope that this helps. I will work to add some kind of automatic multi-selection when more than 1 row is selected from code.

Best regards

Thank you.

I suppose this procedure will be in next release.
Is it right?
