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>
