C#使用对象绑定ListView项

Question

什么是将ListView项目与对象绑定的最佳方式,因此当我将项目从一个列表视图移动到另一个列表视图时,我仍然能够告诉它分配了什么对象.例如,我有对象Cards.所有这些都列在一个allCards ListView.我有另一个selectedCards ListView按钮,将所选项目从一个列表视图移动到另一个列表视图.当我完成我的选择时,我需要获取Card移动到selectedCardsListView 的对象列表.

您可以使用可观察的集合,并为您的Card类创建一个datatemplate .然后你只需要绑定ListView到集合,它就会为你完成所有的工作.当您添加一个项目到ObservableCollection了ListView自动重绘.

using System.Collections.ObjectModel;

<ListView Name="allCardsView" Source="{Binding}">
    <ListView.ItemTemplate>
        <DataTemplate DataType="{x:Type yourXmlns:Card}">
            //Your template here
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>
<ListView Name="selectedCardsView" Source="{Binding}">
    <ListView.ItemTemplate>
        <DataTemplate DataType="{x:Type yourXmlns:Card}">
            //Your template here
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

ObservableCollection<Card> allCards = new ObservableCollection<Card>();
ObservableCollection<Card> selectedCards = new ObservableCollection<Card>();
allCardsView.DataContext = allCards;
selectedCardsView.DataContext = selectedCards;


public void ButtonClickHandler(object sender, EventArgs e) 
{
    if (allCardsView.SelectedItem != null &&
        !selectedCards.Contains(allCardsView.SelectedItem)) 
    {
        selectedCards.Add(allCardsView.SelectedItem);
    }
}

要扩展@ CharithJ的答案,这就是你如何使用tag属性:

    ListView allCardsListView = new ListView();
    ListView selectedCardsListView = new ListView();
    List<Card> allCards = new List<Card>();
    List<Card> selectedCards = new List<Card>();
    public Form1()
    {
        InitializeComponent();


        foreach (Card selectedCard in selectedCards)
        {
            ListViewItem item = new ListViewItem(selectedCard.Name);
            item.Tag = selectedCard;
            selectedCardsListView.Items.Add(item);
        }
        foreach (Card card in allCards)
        {
            ListViewItem item = new ListViewItem(card.Name);
            item.Tag = card;
            allCardsListView.Items.Add(new ListViewItem(card.Name));
        }

        Button button = new Button();
        button.Click += new EventHandler(MoveSelectedClick);
    }

    void MoveSelectedClick(object sender, EventArgs e)
    {
        foreach (ListViewItem item in allCardsListView.SelectedItems)
        {
            Card card = (Card) item.Tag;
            //Do whatever with the card
        }
    }

显然你需要根据自己的代码进行调整,但这应该让你开始.
