一个基本数据绑定通常包括4个部分，绑定目标、绑定目标属性、源目标、源目标属性下面的例子就是一个简单的单向数据绑定。

首先进行简单的布局，界面如下

源代码如下

<Grid Name="layout" Background="{StaticResource ApplicationPageBackgroundThemeBrush}">        <TextBlock HorizontalAlignment="Left" Margin="300,242,0,0" TextWrapping="Wrap" Text="员工信息表" VerticalAlignment="Top" Height="36" Width="214" FontFamily="Global User Interface" FontSize="30"/>        <TextBlock HorizontalAlignment="Left" Margin="243,307,0,0" TextWrapping="Wrap" Text="姓名：" VerticalAlignment="Top" FontSize="20"/>        <TextBlock HorizontalAlignment="Left" Margin="243,349,0,0" TextWrapping="Wrap" Text="工号：" VerticalAlignment="Top" FontSize="20"/>        <TextBlock HorizontalAlignment="Left" Margin="243,387,0,0" TextWrapping="Wrap" Text="职务：" VerticalAlignment="Top" FontSize="20"/>        <TextBlock HorizontalAlignment="Left" Margin="243,419,0,0" TextWrapping="Wrap" Text="薪资：" VerticalAlignment="Top" FontSize="20"/>        <TextBox Name="txtName" HorizontalAlignment="Left" Margin="308,301,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="195"/>        <TextBox Name="txtNumber" HorizontalAlignment="Left" Margin="308,338,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="195"/>        <TextBox Name="txtPost" HorizontalAlignment="Left" Margin="308,375,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="195"/>        <TextBox Name="txtSalary" HorizontalAlignment="Left" Margin="308,412,0,0" TextWrapping="Wrap" Text="" VerticalAlignment="Top" Width="195"/>

接下来我们要准备源目标，新建一个员工类

public class Employee    {        public string Name{get;set;}        public int Number{get;set;}        public string Post{get;set;}        public double Salary{get;set;}        public Employee(string name,int number,string post,double salary)        {            Name=name;            Number=number;            Post=post;            Salary=salary;        }    }

在主构造函数中做初始化

 public MainPage()        {            this.InitializeComponent();            Employee employee = new Employee("飞机", 222, "3232", 5000.43);            layout.DataContext = employee;            Binding bindingName = new Binding();            bindingName.Mode = BindingMode.OneWay;            bindingName.Path = new PropertyPath("Name");            txtName.SetBinding(TextBox.TextProperty, bindingName);            Binding bindingNumber = new Binding();            bindingNumber.Mode = BindingMode.OneWay;            bindingNumber.Path = new PropertyPath("Number");            txtNumber.SetBinding(TextBox.TextProperty, bindingNumber);            Binding bindingPost = new Binding();            bindingPost.Mode = BindingMode.OneWay;            bindingPost.Path = new PropertyPath("Post");            txtPost.SetBinding(TextBox.TextProperty, bindingPost);            Binding bindingSalary = new Binding();            bindingSalary.Mode = BindingMode.OneWay;            bindingSalary.Path = new PropertyPath("Salary");            txtSalary.SetBinding(TextBox.TextProperty, bindingSalary);        }
