(Disabled when no string in DBEdit.) Following is my code which disables the CheckBox after a delete from the DBEdit. But it is not enabled when I add a string to the DBEdit. ------ procedure TForm4.DBEdit2Change(Sender: TObject); begin if DBEdit2.Text = ' ' then DBCheckBox4.Enabled := True Else if DBEdit2.Text = '''' then DBCheckBox4.Enabled := False ; end; Thanks for any help.
