Which event should i use on DBGrid in order to catch the click on leftmost cell
« on: February 06, 2023, 02:24:30 pm »
Hello all,
while i read the Tdbgrid manual and searched in forums,  i cannot figure out which event i must use in order to catch the click on the leftmost cell (the grayed one, which selects rows) in a dbgrid. I know that columns can be catch with .OnTitleClick but what about rows?

Anybody can help?

L.

Code: Pascal  [Select][+][-]
  1. procedure TForm1.DBGrid1MouseDown(Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer);
  2. var
  3.   aCol, aRow;
  4. begin
  5.   DBGrid1.MouseToCell(X, Y, aCol, aRow);
  6.   if aCol = 0 then
  7.     ShowMessage(Format('Clicked indicator column on row: %d', [aCol, aRow]));
  8. end;

You can change the title to include [solved]

I’ve had difficulty with that first column In dbgrid  causing crashes awhile Ago when I clicked it. Hopefully that was fixed. I remember having to do special handling for that column checking if it was zero etc.

In the first message click to modify, and change the subject, then save.

I did that, this is how i changed the icon to thumbnail. But, unfortunately, i cannot change the subject. Subject box behaves like it is readOnly. Tried with Firefox and Chrome, no luck... Anyway...
