c# - ApplicationBar 绑定(bind) Windows Phone

Question

无法绑定(bind) ApplicationBar，我试过了:

<phone:PhoneApplicationPage.ApplicationBar>
    <shell:ApplicationBar IsVisible="True" IsMenuEnabled="True">
        <shell:ApplicationBarIconButton 
            x:Name="btnTest"
            IconUri="/Assets/AppBar/appbar.add.rest.png" 
            Text="{Binding MyBtnText}" />
    </shell:ApplicationBar>
</phone:PhoneApplicationPage.ApplicationBar>

和

private void MainPage_Loaded(object sender, RoutedEventArgs e)
{
    btnTest.Text = AppResources.Reset;
}

Answer 1

private void MainPage_Loaded(object sender, RoutedEventArgs e)
{
    ApplicationBarIconButton btn= ApplicationBar.Buttons[0] as ApplicationBarIconButton;
    if (btn!= null)
    {
        btn.Text = AppResources.Test;
    }

}

或从 C# 后面的代码构建 ApplicationBar

// Build a localized ApplicationBar
private void BuildLocalizedApplicationBar()
{
    // Set the page's ApplicationBar to a new instance of ApplicationBar.
    ApplicationBar = new ApplicationBar();

    // Create a new button and set the text value to the localized string from AppResources.
    ApplicationBarIconButton appBarButton = 
        new ApplicationBarIconButton(new   
        Uri("/Assets/AppBar/appbar.add.rest.png", UriKind.Relative));
        appBarButton.Text = AppResources.Reset;
    ApplicationBar.Buttons.Add(appBarButton);

    // Create a new menu item with the localized string from AppResources.
    ApplicationBarMenuItem appBarMenuItem = 
        new ApplicationBarMenuItem(AppResources.AppBarMenuItemText);
    ApplicationBar.MenuItems.Add(appBarMenuItem);
}
