数据绑定到对象

首先 我们需要一个对象

 public class Preson





    {





        private string name;





 





        public string Name





        {





            get { return name; }





            set { name = value; }





        }





        private string address;





 





        public string Address





        {





            get { return address; }





            set { address = value; }





        }





        private int  age;





 





        public int Age





        {





            get { return age; }





            set { age = value; }





        }





    }

设置依赖属性绑定数据上下文

        public MainWindow()





        {





            InitializeComponent();





            Preson = new Preson() { Name = "慧哥", Address = "大连", Age = 30 };





            DataContext = Preson;





        }





 





 





 





        public Preson Preson





        {





            get { return (Preson)GetValue(PresonProperty); }





            set { SetValue(PresonProperty, value); }





        }





 





        // Using a DependencyProperty as the backing store for Preson.  This enables animation, styling, binding, etc...





        public static readonly DependencyProperty PresonProperty =





            DependencyProperty.Register("Preson", typeof(Preson), typeof(MainWindow), new PropertyMetadata(null));





 

   <Grid HorizontalAlignment="Right" Width="517">





        <Grid.ColumnDefinitions>





            <ColumnDefinition Width="109*"/>





            <ColumnDefinition Width="112*"/>





            <ColumnDefinition Width="94*"/>





            <ColumnDefinition Width="202*"/>





        </Grid.ColumnDefinitions>





        <Grid.RowDefinitions>





            <RowDefinition Height="24*"/>





            <RowDefinition Height="25*"/>





            <RowDefinition Height="25*"/>





            <RowDefinition Height="86*"/>





        </Grid.RowDefinitions>





        <TextBox HorizontalAlignment="Left" Height="23" Margin="101,27,0,0" Grid.Row="1" TextWrapping="Wrap" Text="{Binding Age,Mode=TwoWay}" VerticalAlignment="Top" Width="120" Grid.ColumnSpan="2" />





        <TextBlock HorizontalAlignment="Left" Margin="41,22,0,0" TextWrapping="Wrap" Text="名字" VerticalAlignment="Top"/>





        <TextBlock HorizontalAlignment="Left" Margin="79,22,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Text="{Binding Name}" Width="30"/>





        <TextBlock HorizontalAlignment="Left" Margin="10,22,0,0" TextWrapping="Wrap" Text="address" VerticalAlignment="Top" Grid.Column="1"/>





        <TextBlock Margin="63.667,22,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Text="{Binding Address}" Grid.Column="1"/>





        <TextBlock HorizontalAlignment="Left" Margin="20,22,0,0" TextWrapping="Wrap" Text="age" VerticalAlignment="Top" Grid.Column="2"/>





        <TextBlock Margin="57,22,0,0" TextWrapping="Wrap" VerticalAlignment="Top" Text="{Binding Age}" Grid.Column="2"/>





        <TextBox HorizontalAlignment="Left" Height="23" Margin="0,17,0,0" Grid.Row="1" TextWrapping="Wrap" VerticalAlignment="Top" Width="120" Grid.ColumnSpan="2" Grid.Column="2" />





    </Grid>

前台WPF绑定

这里也可以用 INotifyPropertyChanged 也可以

集合使用ObservableCollenction<对象>
