C＃Silverlight - 放大到水平列表框圖像項目

我有以下列表框綁定到圖像URL的數據庫表下面的列表框。當應用程序正在運行時，可以點擊每個單獨的圖像，並在圖像上出現一個淺藍色的選擇框（您可以知道每個單獨圖像何時被選中爲點擊）。我希望能夠做的是在點擊每個圖像時進行縮放。有誰知道我可以通過修改我目前使用的代碼來做到這一點嗎？（這樣做的原因是，我需要在水平列表框，這是這段代碼做什麼來顯示圖像。）C＃Silverlight - 放大到水平列表框圖像項目

<ListBox x:Name="list1" HorizontalAlignment="Left" RenderTransformOrigin="0.5,0.5" Width="400" d:LayoutOverrides="HorizontalAlignment"> 
          <ListBox.ItemsPanel> 
           <ItemsPanelTemplate> 
            <StackPanel Orientation="Horizontal"/> 
           </ItemsPanelTemplate>

         </ListBox>

您可以使用您目前使用的ItemTemplate這個片段中還有一個模板GeneratedItemContainer（ItemContainerStyle）

您可以通過重寫控件模板訪問控制ListBoxItem中的visualStateManager。在Expression Blend中，選擇一個ListBoxItem和模板的「編輯副本」。這將複製舊的ListBoxItem控件的樣式和控件模板，以給出一個很好的起始位置，以修改此ListBox控件設置爲處理的關鍵事件上發生的情況。

做完這些之後，您可以在可視狀態管理器中對各種事件（懸停，選擇，禁用等）應用動畫。

如果你是數據綁定你的ItemsSource屬性，並且沒有文字ListBoxItems來產生一個ListBoxItem樣式從頭開始，只需創建一個新的ListBox並添加一個ListBoxItem到它來生成Style + ControlTemplate。一旦生成了樣式，您可以通過在數據綁定ListBox控件的ItemContainerStyle屬性上指定新創建的資源來更改您的數據綁定ListBox項目的控件模板。
