1.把控件作为Binding的源

例子：拖动Slider，输入框中的值也会跟着改变，或在输入框中输入数值，滑动条也会自动移动

 

 2.控制Binding的方向

设置属性：Mode

3.更新时操作

 设置属性：UpdateSourceTrigger

4.Path路径

1)前台与后台的代码比较：

前台：

 

后台：

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;namespace Path路径{    /// 
    /// MainWindow.xaml 的交互逻辑    /// 
    public partial class MainWindow : Window    {        public MainWindow()        {            InitializeComponent();        }        private void Window_Loaded(object sender, RoutedEventArgs e)        {            Binding binding = new Binding() { Path = new PropertyPath("Value"), Source = this.slider1 };            this.textbox2.SetBinding(TextBox.TextProperty, binding);            this.textBox6.SetBinding(TextBox.TextProperty, new Binding("Text.Length") { Source = this.textBox3, Mode = BindingMode.OneWay });            this.textBox9.SetBinding(TextBox.TextProperty, new Binding("Text[3]") { Source = this.textBox7, Mode = BindingMode.OneWay });        }    }}

2)斜线语法

第一个例子：

XAML:

 

C#:

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.Shapes;namespace Path路径{    /// 
    /// 当使用一个集合或者DataView作为Binding的源时,如果想把它的默认元素当作Path使用，需要以下的语法    /// 
    public partial class Window1 : Window    {        public Window1()        {            InitializeComponent();        }        private void Window_Loaded(object sender, RoutedEventArgs e)        {            List
      
        stringList = new List
       
        () { "Tomi", "Tim", "Blogog" };            this.textBox1.SetBinding(TextBox.TextProperty, new Binding("/") { Source = stringList });            this.textBox2.SetBinding(TextBox.TextProperty, new Binding("/Length") { Source = stringList, Mode = BindingMode.OneWay });            this.textBox3.SetBinding(TextBox.TextProperty, new Binding("/[2]") { Source = stringList, Mode = BindingMode.OneWay });        }    }}

    /// 如果集合元素的属性仍然是一个集合时，使用多斜线语法    /// 
    public partial class Window2 : Window    {        public Window2()        {            InitializeComponent();        }        private void Window_Loaded(object sender, RoutedEventArgs e)        {            List
      
        countryList = new List
       
        (){                new Country(){                    Name = "中国",                    ProvinceList = new List
        
         (){                        new Province(){                            Name = "四川",                            CityList = new List
         
          (){                                new City(){                                    Name = "成都"                                }                            }                        }                    }                }            };            this.textBox1.SetBinding(TextBox.TextProperty, new Binding("/Name") { Source = countryList });            this.textBox2.SetBinding(TextBox.TextProperty, new Binding("/ProvinceList/Name") { Source = countryList });            this.textBox3.SetBinding(TextBox.TextProperty, new Binding("ProvinceList/CityList/Name") { Source = countryList });        }    }}
