Does anyone know how to stop a TDbNavigator.OnClick event happening depending on certain conditions examined in the BeforeAction? It seems setting a flag and doing an abort might be the best.  Tom.

Tom,

If button = nbPost then
     If Edit1.Text = '' then      {Required value left out!}
         Begin
          Showmessage('Must enter a value!');
          ABORT;
         End;

Good luck with your project!

Pegasus, thanks a lot, I tied the abort in the onclick based on a flag set in beforeaction and stupidly never tried the abort in the BeforeAction.
