Lgc,

As opposed to actually deleting the column, how about just setting it's visible property to FALSE, thereby hiding it but keeping it "available" for program usage or possible re-display later?

DBGrid.Columns[2].Visible := False;

Good luck with your project!

Sorry, but DBgrid.columns.visible := false and RebuildColumns don't work with persistant field in my program.
Thanks Pegasus and Zifnab.

1. Place a DBGrid on a form.
2. Place a button on a form.
3. Connect the DBGrid to a table that has more then 2 fields.
4. Set Table's Active to true.
5. Write the following code, that deletes the second column:

procedure TForm1.Button1Click(Sender: TObject);
begin
  DBGrid1.Columns.RebuildColumns;
  DBGrid1.Columns.Items[1].Destroy;
end;
