Hi,

I tried to find the solution on the forum, but failed, so I need your
help, again.
I have a DBGrid, and I'm able to hide some columns, but I want to
disable some of the visible colums, too. So, I want that the user will
be able to edit the content of only one column, but the
DBGrid.Columns.Enabled:=False do not work.
Any idea is welcome

TIA
Kyjan

Hi

You can use the OnSelectEditor event and assign nil when you don't
want user's input.

Example :

Code: [Select]procedure TForm1.GridSelectEditor(Sender: TObject; aCol,
aRow: integer; var Editor: TWinControl);

begin
  if RowReadOnly(aRow) then
    Editor := nil
end; 
Hope this helps.
Regards,
Tintinux

The solution was so simple that it is my shame not to think of it:

Code: [Select]Dbgrid1.Columns[1].Readonly:=True;

This will disable the editing of the 1st column.

Thanks, Tintinux, for the idea.
Regards, Kyjan

Yes, I have forgotten this simple feature.
It disable the entire column, and that's what you searched for.

But to disable a row or a cell, my method is useful.
