我似乎無法弄清楚爲什麼列表框項目放在彼此的頂部......他們應該在另一個之下。這裏有一些標記和代碼。列表框項目被放置在彼此頂部
<ListBox x:Name="DeviceList" Background="#ff4c4c4c" BorderThickness="0" ScrollViewer.CanContentScroll="False" MouseEnter="DeviceList_MouseEnter" MouseLeave="DeviceList_MouseLeave"
ManipulationBoundaryFeedback="DeviceList_ManipulationBoundaryFeedback" ItemContainerStyle="{DynamicResource ResourceKey=ListBoxItemStyle}" PreviewMouseDown="DeviceList_PreviewMouseDown"
PreviewMouseMove="DeviceList_PreviewMouseMove" PreviewMouseUp="DeviceList_PreviewMouseUp" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" DockPanel.Dock="Bottom">

public ConfiguratorView()
{
InitializeComponent();
foreach (Device device in (Application.Current.Windows[1].DataContext as ConfiguratorViewModel).AvailableDevices)
{
devices.Add(AddDevice(device.Icon + "_def", device.Description));
}
DeviceList.ItemsSource = devices;
}

private Canvas AddDevice(string icon, string description)
{
Canvas canvas = new Canvas();
canvas.Name = icon;
ContentControl backgroundContent = new ContentControl();
Label label = new Label();
backgroundContent.Template = Application.Current.FindResource(icon) as ControlTemplate;
label.Content = description;
canvas.Children.Add(backgroundContent);
canvas.Children.Add(label);
return canvas;
}
設備列表添加帆布爲項目......然後我設置的ItemsSource到列表中。加載它顯示在最後一個圖標上的所有圖標。有什麼想法嗎?
很難準確地告訴你在顯示的代碼片段中做了什麼,但'Canvas'es是用絕對定位呈現的,這可能是問題的根源...... – 2012-08-08 21:24:10
