How do i handle the event of a selected pivot item in Windows Phone

Question

I have an app with 3 PivotItems and an ApplicationBar. I want to hide the ApplicationBar when the PivotItems 2 and 3 are selected, and show the ApplicationBar when the first PivotItem is selected.

I don't know why this question has been down voted. The question sense may be wrong and it can be edited. I got the solution for you @user3847141. Here you go.

PivotItem pivot = null;
    private void Pivot_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        ApplicationBar appBar = new ApplicationBar();
        ApplicationBarIconButton appBarIconButton = new ApplicationBarIconButton();
        pivot = (PivotItem)(sender as Pivot).SelectedItem;
        switch(pivot.Header.ToString())
        {
            case "item1": 
                appBar.Mode = ApplicationBarMode.Default;
                appBarIconButton.IconUri = new Uri("/appbar.close.png", UriKind.RelativeOrAbsolute);
                appBarIconButton.Text = "Close";
                appBar.Buttons.Add(appBarIconButton);
                this.ApplicationBar = appBar;
                break;
            case "item2":
                appBar.Mode = ApplicationBarMode.Minimized; // To minimize AppBar
                appBar = null; // Delete Application Bar                     
                this.ApplicationBar = appBar;
                break;
            case "item3":
                appBar.Mode = ApplicationBarMode.Minimized;
                appBar = null;                   
                this.ApplicationBar = appBar;
                break;
        }
    }

You can achieve this through Selection_Changed event in Pivot. Hope it helps.
