在Windows手机中拖放

我正在尝试实施拖放功能来安排列表框的内容。我能够拖动该项目。当我尝试将第二个项目拖动到第一个项目时,它会显示在第一个项目上,但是当我尝试将第一个项目拖动到第二个项目时,则第一个项目会转到第二个项目下面。我也无法抓住掉落,所以我可以安排这些物品。

有人可以帮我吗?

这是我正在使用的代码示例

 <ListBox Name="lstBoxImages" ScrollViewer.VerticalScrollBarVisibility="Disabled">
            <ListBox.ItemsPanel>
                <ItemsPanelTemplate>
                    <toolkits:WrapPanel 
                                Width="450" 
                                Height="Auto" 
                                ItemWidth="225" 
                                ItemHeight="Auto"/>
                </ItemsPanelTemplate>
            </ListBox.ItemsPanel>
            <ListBox.ItemTemplate>
                <DataTemplate>

                    <StackPanel Orientation="Horizontal">
                        <Image Source="{Binding Source}" Height="200" Width="200" MouseMove="MouseMoving">
                            <i:Interaction.Behaviors>
                            <el:MouseDragElementBehavior ConstrainToParentBounds="False"/>
                        </i:Interaction.Behaviors>

                        </Image>
                    </StackPanel>


                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

代码背后:

protected override void OnNavigatedTo(NavigationEventArgs e)
    {
        base.OnNavigatedTo(e);
        List<ImageInfo> lstImages = new List<ImageInfo>();
        lstImages.Add(new ImageInfo() { ImageID = 1, Source = "Images/4.png" });
        lstImages.Add(new ImageInfo() { ImageID = 2, Source = "Images/2.png" });
        lstImages.Add(new ImageInfo() { ImageID = 3, Source = "Images/4.png" });
        lstImages.Add(new ImageInfo() { ImageID = 4, Source = "Images/2.png" });
        lstImages.Add(new ImageInfo() { ImageID = 5, Source = "Images/4.png" });
        lstImages.Add(new ImageInfo() { ImageID = 6, Source = "Images/2.png" });

        lstBoxImages.ItemsSource = lstImages;

    }

    private void MouseMoving(object sender, System.Windows.Input.MouseEventArgs e)
    {
        Image realSender = (Image)sender;
        int zIndex = Canvas.GetZIndex(realSender);
        Canvas.SetZIndex(realSender, zIndex++);
    }

我的信息类是:

public class ImageInfo
{
    private int _ImageID;
    private string _Source;

    public string Source
    {
        get { return _Source; }
        set { _Source = value; }
    }

    public int ImageID
    {
        get { return _ImageID; }
        set { _ImageID = value; }
    }
}

您可以尝试从Bewise phone controls工具包中控制可订购列表 来自Telerik RadControls for Windows Phone的DataBoundListBox也支持重新排序的项目。
