在這個教程中我們將學習如何創建一個包含動態全景控件的 Windows Phone 7 應用程序。關於什麼是全景控件請看本文最後的運行截圖。
首先打開 Visual Studip 2010 並創建一個新的 Sliverlight for Windows Phone 7 的項目：
開始編碼之前，我們通過添加引用選項來添加 Microsoft.Phone.Controls 的引用，並在 XAML 代碼中包含命名空間，並刪除 xaml 代碼中的默認內容：
現在讓我們開始編碼。全景空間包含不同的標題和條目：
01
private List<string> CreatePanoramaItems(string item)
02
{
03
List<String> Panoramaitems = null;
04
switch (item)
05
{
06
case "Page1":
07
Panoramaitems = new List<string> { "Page1Item1", "Page1Item2", "Page1Item3"};
08
break;
09
case "Page2":
10
Panoramaitems = new List<string> { "Page2Item1", "Page2Item2", "Page2Item3" };
11
break;
12
case "Page3":
13
Panoramaitems = new List<string> { "Page3Item1", "Page3Item2", "Page3Item3" };
14
break;
15
}
16
return Panoramaitems;
17
}
18
19
private List<string> CreatePanoramaHeaders()
20
{
21
return new List<string> { "Page1", "Page2", "Page3" };
22
}
接下來是添加裝載事件，當頁面加載時我們要裝載動態的全景控件，並自定義標題和列表項：
01
private void MainPage_Loaded(object sender, RoutedEventArgs e)
02
{
03
//Initializing the Panorama Control and Assigning base values
04
Panorama panoramactrl = new Panorama();
05
panoramactrl.Title = "F5Debug How To";
06
panoramactrl.SelectionChanged += panoramaCtrl_SelectionChanged;
07
08
//Initializing the Panorama Control Items
09
PanoramaItem panoramaCtrlItem = new PanoramaItem();
10
panoramaCtrlItem.Header = "Dynamic Panorama";
11
12
//Initializing Textblock to display some text
13
TextBlock textBlock = new TextBlock();
14
textBlock.TextWrapping = TextWrapping.Wrap;
15
textBlock.Text = "F5debug.Net – Building and Debugging the Technology";
16
textBlock.FontSize = 20;
17
panoramaCtrlItem.Content = textBlock;
18
19
panoramactrl.Items.Add(panoramaCtrlItem);
20
21
foreach (string Eachitems in CreatePanoramaHeaders())
22
{
23
panoramaCtrlItem = new PanoramaItem();
24
panoramaCtrlItem.Header = Eachitems;
25
panoramactrl.Items.Add(panoramaCtrlItem);
26
}
27
28
this.LayoutRoot.Children.Add(panoramactrl);
29
}
30
31
private void panoramaCtrl_SelectionChanged(object sender, SelectionChangedEventArgs e)
32
{
33
Panorama panoramactrl = (Panorama)sender;
34
PanoramaItem panoramaItem = (PanoramaItem)(panoramactrl.SelectedItem);
35
36
if (panoramaItem.Content == null)
37
{
38
ListBox listBox = new ListBox();
39
listBox.ItemsSource = CreatePanoramaItems(panoramaItem.Header.ToString());
40
panoramaItem.Content = listBox;
41
}
42
}

現在我們已經完成了所有的編碼工作，按 F5 直接運行看看效果，如果編譯成功的話會打開 Windows Phone 模擬器，然後你可以看到如下運行結果：
