WPF備忘錄六(資料繫結篇)

以下示例程式碼通過ListBox來繫結一個實體類的資料，如下：

1、新建一個類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();
        }
    }
}
