WPF備忘錄六(資料繫結篇)

以下範例程式碼通過ListBox來綁定一個實體類的資料，如下：

1、建立一個類Student.cs檔案

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.ComponentModel;namespace Demo{    public class Student : INotifyPropertyChanged    {        private string name;        public event PropertyChangedEventHandler PropertyChanged;        public Student(string name)        {            this.name = name;        }        public string Name        {            get { return name; }            set            {                this.name = value;                OnPropertyChanged("Name");            }        }        public void OnPropertyChanged(string propertyName)        {            if (PropertyChanged != null)            {                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));            }        }    }}

MainWindow.xaml

<Window x:Class="Demo.MainWindow"        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"        xmlns:src="clr-namespace:Demo"        Title="WPF資料繫結" Height="350" Width="525" WindowStyle="ToolWindow">    <Grid>        <Grid.Resources>            <src:Data x:Key="students"></src:Data>            <DataTemplate x:Key="stuDatas">                <TextBlock Text="{Binding Path=Name}"></TextBlock>            </DataTemplate>        </Grid.Resources>        <ListBox ItemTemplate="{StaticResource stuDatas}" Height="23" HorizontalAlignment="Left" Margin="22,12,0,0" Name="listBox1" VerticalAlignment="Top" Width="131">            <ListBox.ItemsSource>                <Binding Source="{StaticResource students }"></Binding>            </ListBox.ItemsSource>        </ListBox>    </Grid></Window>

MainWindow.xaml.cs檔案內容：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Windows;using System.Windows.Controls;using System.Windows.Data;using System.Windows.Documents;using System.Windows.Input;using System.Windows.Media;using System.Windows.Media.Imaging;using System.Windows.Navigation;using System.Windows.Shapes;using System.Windows.Media.Animation;namespace Demo{    /// <summary>    /// MainWindow.xaml 的互動邏輯    /// </summary>    public partial class MainWindow : Window    {        public MainWindow()        {            InitializeComponent();        }    }}
