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
<Window x:Class="把控件作为Binding源.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Grid>
<StackPanel>
<TextBox x:Name="textBox1" Text="{Binding Path=Value,ElementName=slider1,Mode=Default,UpdateSourceTrigger=PropertyChanged}" Margin="5" BorderBrush="Black"></TextBox>
<Slider x:Name="slider1" Maximum="100" Minimum="0" Margin="5"></Slider>
</StackPanel>
</Grid>
</Window>
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：
<Window x:Class="Path路径.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="279.8" Width="525" Loaded="Window_Loaded">
<Grid>
<StackPanel>
<TextBox x:Name="textBox1" Text="{Binding Path=Value,ElementName=slider1,Mode=Default,UpdateSourceTrigger=PropertyChanged}" BorderBrush="Black" Margin="4"></TextBox>
<TextBox x:Name="textbox2" BorderBrush="Black" Margin="4" Text="1"></TextBox>
<Slider x:Name="slider1" Maximum="100" Minimum="0"></Slider> <TextBox x:Name="textBox3" Margin="5" BorderBrush="Red"></TextBox>
<TextBox x:Name="textBox4" Text="{Binding Path=Text.Length,ElementName=textBox3,Mode=OneWay}" Margin="5" BorderBrush="Red"></TextBox>
<TextBox x:Name="textBox6" Margin="5" BorderBrush="Red"></TextBox> <TextBox x:Name="textBox7" Margin="5" BorderBrush="Blue"></TextBox>
<TextBox x:Name="textBox8" Text="{Binding Path=Text[3],ElementName=textBox7,Mode=OneWay}" Margin="5" BorderBrush="Blue"></TextBox>
<TextBox x:Name="textBox9" Margin="5" BorderBrush="Blue"></TextBox>
</StackPanel>
</Grid>
</Window>
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
{
/// <summary>
/// MainWindow.xaml 的交互逻辑
/// </summary>
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:
<Window x:Class="Path路径.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" Height="124.176" Width="300" Loaded="Window_Loaded">
<Grid>
<StackPanel>
<TextBox x:Name="textBox1" Margin="5" BorderBrush="Blue"></TextBox>
<TextBox x:Name="textBox2" Margin="5" BorderBrush="Blue"></TextBox>
<TextBox x:Name="textBox3" Margin="5" BorderBrush="Blue"></TextBox>
</StackPanel>
</Grid>
</Window>
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
{
/// <summary>
/// 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
/// </summary>
public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
} private void Window_Loaded(object sender, RoutedEventArgs e)
{
List<string> stringList = new List<string>() { "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 });
}
}
}

XAML:
<Window x:Class="Path路径.Window2"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<StackPanel>
<TextBox x:Name="textBox1" Margin="5" BorderBrush="Blue"></TextBox>
<TextBox x:Name="textBox2" Margin="5" BorderBrush="Blue"></TextBox>
<TextBox x:Name="textBox3" Margin="5" BorderBrush="Blue"></TextBox>

public partial class Window2 : Window

} private void Window_Loaded(object sender, RoutedEventArgs e)
{
List<Country> countryList = new List<Country>(){
new Country(){

new Province(){
Name = "四川",
CityList = new List<City>(){
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 });
