C# 如何将itemSource绑定到xaml中的列表

在C#中：

名称空间滑块
{
公共部分类主页：PhoneApplicationPage
{
//建造师
私人弹出窗口；
私人背景工作者背景工作者；
公共列表页；

在XAML中：

namespace Slider
{
public partial class MainPage : PhoneApplicationPage
{
    // Constructor
    private Popup popup;
    private BackgroundWorker backroungWorker;
    public List<Pages> pages;

您不能绑定到列表，否则当列表更改时，视图（xaml）将永远不会收到通知。这就是为什么您必须使用ObservableCollection

这里有一个与MVVM模式和datagrid类似的示例：

<phone:PhoneApplicationPage
x:Class="Starz.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
etc....

<phone:PivotItem Header="Browse Pages">
            <!--Double line list no text wrapping-->
            <phone:LongListSelector x:Name="pages" Margin="0,0,-12,0"  ItemSource ="{Binding pages}">

MVVM示例

假设您有一个带有datagrid的windows：

<phone:PhoneApplicationPage
x:Class="Starz.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:phone="clr-namespace:Microsoft.Phone.Controls;assembly=Microsoft.Phone"
xmlns:shell="clr-namespace:Microsoft.Phone.Shell;assembly=Microsoft.Phone"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
etc....

<phone:PivotItem Header="Browse Pages">
            <!--Double line list no text wrapping-->
            <phone:LongListSelector x:Name="pages" Margin="0,0,-12,0"  ItemSource ="{Binding pages}">

然后我们可以定义ViewModel（窗口的datacontext）：

namespace WpfApplication7
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            this.DataContext = new MainViewModel(this);
        }
    }
}

class MainViewModel : ViewModelBase
    {
        /// <summary>
        /// Référence de la fenêtre principale
        /// </summary>
        private MainWindow mainWindow;

        /// <summary>
        /// Liste des personels
        /// </summary>
        private ObservableCollection<Personel> personels = new ObservableCollection<Personel>();


        public ObservableCollection<Personel> Personels
        {
            get 
            {
                return personels;
            }
        }

        /// <summary>
        /// Constructeur de la classe
        /// </summary>
        /// <param name="mainWindow">Référence de la fenêtre principale</param>
        public MainViewModel(MainWindow mainWindow)
        {
            this.mainWindow = mainWindow;

            AddPersonel("Toto");

            AddPersonel("Jack");

            AddPersonel("Momo");

            AddPersonel("Momo");

            AddPersonel("Momo");

            AddPersonel("Momo");
        }

        private void AddPersonel(string namePersonel)
        {
            personels.Add(new Personel() { Name = namePersonel });
            OnPropertyChanged("Personels");
        }
    }

    class Personel
    {
        private string name = "NoName";

        public string Name
        {
            get { return name; }
            set { name = value; }
        }
    }

public abstract class ViewModelBase : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;

        protected virtual void OnPropertyChanged(string propertyName)
        {
            if (this.PropertyChanged != null)
            {
                this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
            }
        }
    }
