WPF绑定基础

1、

XAML：<TextBox Name="textbox1"></TextBox>

cs:

    public class Customer
    {
        public string Name { get;set;}
    }

           Customer customer = new Customer()
            {
                Name = "Zhangjinshan"
            };
            Binding bind = new Binding();
            bind.Source = customer;

            bind.Path = new PropertyPath("Name");
            textbox1.SetBinding(TextBox.TextProperty, bind);

2、

XAML: <TextBox Name="textbox1" Text="{Binding Path=Name}"></TextBox>

cs:

           Customer customer = new Customer()
            {
                Name = "Zhangjinshan"
            };
            textbox1.DataContext = customer;

 

3、

XAML:

   <Window.Resources>
        <my:Customer x:Key="mycustomer" Name="ZhangJinshan"/>
    </Window.Resources>
    <StackPanel>
        <StackPanel.DataContext>
            <StaticResource ResourceKey="mycustomer"/>
        </StackPanel.DataContext>
        <TextBox Name="textbox1" Text="{Binding Path=Name}"/>
    </StackPanel>

 

4、

<Window.Resources>
        <my:Customer x:Key="mycustomer" Name="Zhangjinshan"/>
    </Window.Resources>
    <StackPanel>
        <TextBox Name="textbox1" Text="{Binding Path=Name, Source={StaticResource ResourceKey=mycustomer}}"/>
    </StackPanel>

 

 

有一个问题，就是很多地方都写可以这样绑定：

<TextBox DataContext="{Binding ElementName=customer}" Text="{Binding Path=Name}"/>

 可我怎么试都不行，可能是我理解有误：代码如下：

XAML:

<TextBox DataContext="{Binding ElementName=customer}" Text="{Binding Path=Name}"/>

cs:

Customer customer = new Customer()
            {
                Name = "Zhangjinshan"
            };

请高人指点。。。。
