"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.


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);

Thanks RONIT you have the response for my problem.
