Stop page refresh

[jrosh]

I use Mvc 4 with razor. I have a View that in back end creates a database entry in Action method. Problem is when i refresh the page (Press F5) the back end method calls again and create duplicate of the database entry. How to stop this?

 public ActionResult SummaryPage()
 { 
    bool createdatabaseEntry = NotifyCreateDatabaseEntry();

   if (createdatabaseEntry)
    {
        // pop up success massage
    }
    else
    {
        // pop up error massage
    }

     return View();
 }

 public bool createdatabaseEntry : this method connect to the db

Please help
thank you in advance
