前台代码:
<navigation:Page x:Class="dataBind.bindPerson"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:navigation="clr-namespace:System.windows.Controls;assembly=System.windows.Controls.Navigation"
d:DesignWIDth="640" d:DesignHeight="480"
title="bindPerson Page">
<GrID x:name="LayoutRoot">
<TextBox Height="23" HorizontalAlignment="left" margin="133,122,0" name="textBox1" VerticalAlignment="top" WIDth="120" Text="{Binding name,Mode=TwoWay}" />
<button Content="显示" Height="23" HorizontalAlignment="left" margin="157,191,0" name="button1" VerticalAlignment="top" WIDth="75" Click="button1_Click" />
<button Content="设置" Height="23" HorizontalAlignment="left" margin="299,192,0" name="button2" VerticalAlignment="top" WIDth="75" Click="button2_Click" />
<TextBox Height="23" HorizontalAlignment="left" margin="278,0" name="textBox2" VerticalAlignment="top" WIDth="120" Text="{Binding Age,Mode=TwoWay}" />
</GrID>
</navigation:Page>
我们需要添加一个person类:
using System;
using System.Net;
using System.windows;
using System.windows.Controls;
using System.windows.documents;
using System.windows.Ink;
using System.windows.input;
using System.windows.Media;
using System.windows.Media.Animation;
using System.windows.Shapes;
namespace dataBind
{
public class person:DependencyObject
{
private string name;
//public string name
//{
// get { return name; }
// set { name = value; }
//}
public string name
{
get { return (string)GetValue(nameProperty); }
set { SetValue(nameProperty,value); }
}
// Using a DependencyProperty as the backing store for name. This enables animation,styling,binding,etc...
public static Readonly DependencyProperty nameProperty =
DependencyProperty.Register("name",typeof(string),typeof(person),null );
private int age;
//public int Age
//{
// get { return name; }
// set { name = value; }
//}
public int Age
{
get { return (int)GetValue(AgeProperty); }
set { SetValue(AgeProperty,value); }
}
// Using a DependencyProperty as the backing store for Age. This enables animation,etc...
public static Readonly DependencyProperty AgeProperty =
DependencyProperty.Register("Age",typeof(int),null );
}
}
后台代码:
using System;
using System.Collections.Generic;
using System.linq;
using System.Net;
using System.windows;
using System.windows.Controls;
using System.windows.documents;
using System.windows.input;
using System.windows.Media;
using System.windows.Media.Animation;
using System.windows.Shapes;
using System.windows.Navigation;
namespace dataBind
{
public partial class bindPerson : Page
{
public bindPerson()
{
InitializeComponent();
}
person p = new person() { name = "张三",Age = 27 };
// 当用户导航到此页面时执行。
protected overrIDe voID OnNavigatedTo(NavigationEventArgs e)
{
}
private voID button1_Click(object sender,RoutedEventArgs e)
{
textBox1.DataContext = p;
textBox2.DataContext = p;
MessageBox.Show("姓名:" + p.name + "\n年龄:" + p.Age);
}
private voID button2_Click(object sender,RoutedEventArgs e)
{
p.name = "安亭";
p.Age = 23;
MessageBox.Show("姓名:" + p.name + "\n年龄:" + p.Age);
}
} }
