I'm getting the first element of a table articles where column(statusArticle=false).The problem is that i want to refresh the form after the button click so i can interact with next element, but the form is not refreshed, i tried several codes exept the one of application.restart that is heavy! How can i refresh the form at the boutton click without restarting application?

   private void button_Click(object sender, EventArgs e)
        {
            using (DbEntities db = new DbEntities())
            {
               Articles firstArticle = db.Articles.FirstOrDefault(u => u.statusArticle == false);
                if (firstArticle != null)
                {
                    firstArticle.statusArticle = true;
                    db.SaveChanges();
                    MessageBox.Show("Article validated", "OK");
                    this.Refresh();
                }
            }
        }

Answer 1

Within your class create the following:

private void ShowArticle(Article article)
{
  /* The code currently in your constructor for displaying the 
     first article goes here */
}

For your constructor:

public MyForm()
{
  using(DbEntities db = new DbEntities())
  {
    Articles firstArticle = db.Articles.FirstOrDefault(u => u.statusArticle == false);
    if( firstArticle != null ) ShowArticle( firstArticle );
  }
}

In your button click handler instead of calling Refresh simple replace it with a call to ShowArticle passing in "firstArticle". The code above could be cleaned up a bit, but it should do.
