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?

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TForm1.DBGrid1MouseDown(Sender: TObject; Button: TMouseButton; Shift:
TShiftState; X, Y: Integer);var  aCol, aRow;begin 
DBGrid1.MouseToCell(X, Y, aCol, aRow);  if aCol = 0 then   
ShowMessage(Format('Clicked indicator column on row: %d', [aCol,
aRow]));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...
