概述 MainPage.xaml Code: <UserControl xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" x:Class="SilverlightApplication18.MainPage" xmlns="http://schemas.micro

 MainPage.xaml Code:

<UserControl xmlns:data="clr-namespace:System.windows.Controls;assembly=System.windows.Controls.Data" x:Class="SilverlightApplication18.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/Expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d" d:DesignWIDth="640" d:DesignHeight="480"> <GrID x:name="LayoutRoot"> <GrID HorizontalAlignment="left" WIDth="4"/> <data:DataGrID Height="150" margin="74,38,63,0" VerticalAlignment="top" x:name="dgperson"/> <ListBox margin="74,212,206" x:name="lbtxt"/> </GrID></UserControl>

 MainPage.xaml.cs Code:

using System;using System.Collections.Generic;using System.linq;using System.Net;using System.windows;using System.windows.Controls;using System.windows.documents;using System.windows.input;using System.windows.Media;using System.windows.Media.Animation;using System.windows.Shapes;using System.ComponentModel;using System.Collections.ObjectModel;namespace SilverlightApplication18{ public class Person:INotifyPropertyChanged { private string fristname; public string Fristname { get { return fristname; } set { if (value != fristname) { fristname = value; OnPropertyChanged(this,"Fristname"); } } } private string lastname; public string Lastname { get { return lastname; } set { if (value != lastname) { lastname = value; OnPropertyChanged(this,"Lastname"); } } } private string fullname; public string Fullname { set { fullname = Fristname + Lastname; if (value != fullname) { value = fullname; OnPropertyChanged(this,"Fullname"); } } get { return (Fristname + Lastname); } } public event PropertyChangedEventHandler PropertyChanged; voID OnPropertyChanged(object sender,string value) { if (this.PropertyChanged != null) { PropertyChanged(sender,new PropertyChangedEventArgs(value)); } } } public partial class MainPage : UserControl { ObservableCollection<Person> GetPerson() { ObservableCollection<Person> objperson = new ObservableCollection<Person>(); objperson.Add(new Person { Fristname="churen",Lastname="youzi1"}); objperson.Add(new Person { Fristname = "churen2",Lastname = "youzi2" }); objperson.Add(new Person { Fristname = "churen3",Lastname = "youzi2" }); return objperson; } public ObservableCollection<Person> ObPerson; public MainPage() { InitializeComponent(); this.Loaded += new RoutedEventHandler(MainPage_Loaded); } voID MainPage_Loaded(object sender,RoutedEventArgs e) { ObPerson = GetPerson(); this.dgperson.ItemsSource = ObPerson; this.lbtxt.ItemsSource = ObPerson; this.lbtxt.displayMemberPath = "Lastname"; } }}
