Silverlight 之数据绑定（简单例子）

首先我们先明确Databinding Mode的3种模式：

其中，用于OneWay和TwoWay绑定的对象都必须实现“INotifyPropertyChanged”接口

实现范例：

    public class TESTClass : INotifyPropertyChanged
    {
        public event PropertyChangedEventHandler PropertyChanged;

        privatE int _id;
        public int id
        {
            get
            {
                return _id;
            }

            set
            {
                _id = value;
                _name = "Name" + value;
                if (PropertyChanged != null)
                {
                    PropertyChanged.Invoke(this,new PropertyChangedEventArgs("Name"));
                }
            }
        }

        private String _name="Text Box";
        public String Name
        {
            get
            {
                return _name;
            }

            set
            {
                _name = value;
            }
        }
    }

首先需要引入绑定对象的命名空间：

xmlns:local="clr-namespace:TestPhoneApp"

<phone:PhoneApplicationPage.resources>
        <local:TESTClass x:Key="TESTClass"/>
    </phone:PhoneApplicationPage.resources>

<TextBox Height="72" HorizontalAlignment="Left" Margin="0,186,0" Name="textBox2" Text="{Binding Path=Id,Mode=OneTime,source={Staticresource TESTClass}}" VerticalAlignment="Top" Width="460" />
            <TextBox Height="72" HorizontalAlignment="Left" Margin="0,287,0" Name="textBox3" Text="{Binding Path=Name,Mode=OneWay,source={Staticresource TESTClass}}" VerticalAlignment="Top" Width="460" />
