Cara: Menentukan Cakupan Nama
Untuk menganimasikan dalam Storyboard kode, Anda harus membuat NameScope dan mendaftarkan nama objek target dengan elemen yang memiliki cakupan nama tersebut. Dalam contoh berikut, dibuat NameScope untuk myMainPanel
. Dua tombol, button1
dan button2
, ditambahkan ke panel, dan namanya terdaftar. Beberapa animasi dan dibuat Storyboard . Metode papan Begin cerita digunakan untuk memulai animasi.
Karena button1
, button2
, dan myMainPanel
semua memiliki cakupan nama yang sama, salah satunya dapat digunakan dengan StoryboardBegin metode untuk memulai animasi.
Contoh
using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
namespace Microsoft.Samples.Animation.AnimatingWithStoryboards
{
public class ScopeExample : Page
{
private Storyboard myStoryboard;
private StackPanel myMainPanel;
private Button button1, button2;
public ScopeExample()
{
this.Background = Brushes.White;
myMainPanel = new StackPanel();
// Create a name scope for the stackpanel.
NameScope.SetNameScope(myMainPanel, new NameScope());
myMainPanel.Background = Brushes.Orange;
button1 = new Button();
button1.Name = "Button1";
// Register button1's name with myMainPanel.
myMainPanel.RegisterName(button1.Name, button1);
button1.Content = "Button 1";
button1.Click += new RoutedEventHandler(button1Clicked);
myMainPanel.Children.Add(button1);
button2 = new Button();
button2.Name = "Button2";
// Register button2's name with myMainPanel.
myMainPanel.RegisterName(button2.Name, button2);
button2.Content = "Button 2";
button2.Click += new RoutedEventHandler(button2Clicked);
myMainPanel.Children.Add(button2);
// Create some animations and a storyboard.
DoubleAnimation button1WidthAnimation =
new DoubleAnimation(300, 200, new Duration(TimeSpan.FromSeconds(5)));
Storyboard.SetTargetName(button1WidthAnimation, button1.Name);
Storyboard.SetTargetProperty(button1WidthAnimation, new PropertyPath(Button.WidthProperty));
DoubleAnimation button2WidthAnimation =
new DoubleAnimation(300, 200, new Duration(TimeSpan.FromSeconds(5)));
Storyboard.SetTargetName(button2WidthAnimation, button2.Name);
Storyboard.SetTargetProperty(button2WidthAnimation, new PropertyPath(Button.WidthProperty));
DoubleAnimation heightAnimationWithoutTarget =
new DoubleAnimation(300, 200, new Duration(TimeSpan.FromSeconds(5)));
Storyboard.SetTargetProperty(heightAnimationWithoutTarget, new PropertyPath(FrameworkElement.HeightProperty));
myStoryboard = new Storyboard();
myStoryboard.Children.Add(button1WidthAnimation);
myStoryboard.Children.Add(button2WidthAnimation);
myStoryboard.Children.Add(heightAnimationWithoutTarget);
this.Content = myMainPanel;
}
private void button1Clicked(object sender, RoutedEventArgs args)
{
// Starts the animations. The animation without a specified
