列表视图和拖动项目Windows Phone 8.1

Question

我正在使用Windows Phone行为。也许你能以某种方式帮助我。

我想要一个listview，我可以从中将项目拖到另一个Gridview。

到目前为止，我通过设置ReorderMode =“Enabled”来启用拖动。这样做有一些缺点。

1. I'm not able to scroll in my listview anymore 
2. I can't select items anymore 
3. I don't want the items to be reordered 

我想有：

1. When holding an item, I want to drag this to another gridview 
2. I want still be able to scroll in the listview 
3. I still want to be able to select items 

这个现象的原因可能要在Windows Phone 8.1做？我可以自己拖动吗？是的，我该如何开始？！

任何非常感谢指教

ReorderMode并不是要你在这种情况下想要的。下面是一些基本的功能两个列表视图之间做到这一点：

<StackPanel Orientation="Horizontal" Width="800"> 
    <ListView x:Name="ListView1" HorizontalAlignment="Left" DragItemsStarting="ListView_DragItemsStarting" AllowDrop="True" CanDragItems="True" CanReorderItems="True" Drop="ListView_Drop"/> 
    <ListView x:Name="ListView2" HorizontalAlignment="Right" DragItemsStarting="ListView_DragItemsStarting" AllowDrop="True" CanDragItems="True" CanReorderItems="True" Drop="ListView_Drop"/> 
</StackPanel> 

ObservableCollection<string> AlphabetList; 
ObservableCollection<string> NumberList; 
protected override void OnNavigatedTo(NavigationEventArgs e) 
{ 
    AlphabetList = new ObservableCollection<string>(); 
    AlphabetList.Add("A"); 
    AlphabetList.Add("B"); 
    AlphabetList.Add("C"); 
    AlphabetList.Add("D"); 
    AlphabetList.Add("E"); 
    AlphabetList.Add("F"); 
    AlphabetList.Add("G"); 
    AlphabetList.Add("H"); 
    AlphabetList.Add("I"); 
    AlphabetList.Add("J"); 
    ListView1.ItemsSource = AlphabetList; 

    NumberList = new ObservableCollection<string>(); 
    NumberList.Add("0"); 
    NumberList.Add("1"); 
    NumberList.Add("2"); 
    NumberList.Add("3"); 
    NumberList.Add("4"); 
    NumberList.Add("5"); 
    NumberList.Add("6"); 
    NumberList.Add("7"); 
    NumberList.Add("8"); 
    NumberList.Add("9"); 
    ListView2.ItemsSource = NumberList; 
} 

IList<object> DraggedItems; 

private void ListView_DragItemsStarting(object sender, DragItemsStartingEventArgs e) 
{ 
    DraggedItems = e.Items; 
} 

private void ListView_Drop(object sender, DragEventArgs e) 
{ 
    ListView ThisListView = sender as ListView; 
    ObservableCollection<string> AddingOC = (ThisListView.Name == "ListView1" ? AlphabetList :NumberList); 
    ObservableCollection<string> RemovingOC = (ThisListView.Name == "ListView1" ? NumberList : AlphabetList); 

    if (AddingOC.Contains(DraggedItems[0])) return; 
    foreach (string O in DraggedItems) 
    { 
     RemovingOC.Remove(O); 
     AddingOC.Add(O); 
    } 
}
