[原]如何在Silverlight中使用WebService绑定DataGrid

Page.xaml


<UserControl x:Class="SilverlightApplication15.Page"
    xmlns
="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x
="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:data
="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"
    
>
    
<Grid x:Name="LayoutRoot" Background="White" Loaded="LayoutRoot_Loaded">
        
<data:DataGrid x:Name="dgrd_DataGrid" Margin="5" AutoGenerateColumns="False" >
            
<data:DataGrid.Columns>
                
<data:DataGridTextColumn Header="姓名" Width="150" 
                                         Binding
="{Binding UserName}">
                
</data:DataGridTextColumn>
                
<data:DataGridTextColumn Header="年龄" Width="150" 
                                         Binding
="{Binding UserAge}">
                
</data:DataGridTextColumn> "
            
</data:DataGrid.Columns>
        
</data:DataGrid>
    
</Grid>
</UserControl>

 

Page.xaml.cs


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.Collections.ObjectModel;

namespace SilverlightApplication15
{
    
public partial class Page : UserControl
    {
        
public Page()
        {
            InitializeComponent();
            
        }
        
void GetUser()
        {
            UserService.Service1SoapClient userService 
= new SilverlightApplication15.UserService.Service1SoapClient();
            userService.GetUserCompleted 
+= new EventHandler<SilverlightApplication15.UserService.GetUserCompletedEventArgs>(userService_GetUserCompleted);
            userService.GetUserAsync();

        }

        
void userService_GetUserCompleted(object sender, SilverlightApplication15.UserService.GetUserCompletedEventArgs e)
        {
            
if (e.Error == null)
            {
                List
<UserTest> user = new List<UserTest>();
                ObservableCollection
<SilverlightApplication15.UserService.User> list = e.Result;
                
for (int i = 0; i < list.Count; i++)
                {
                    user.Add(
new UserTest
                    {
                        UserName 
= list[i].UserName,
                        UserAge 
= list[i].UserAge
                    });
                }
                
this.dgrd_DataGrid.ItemsSource = user;
            }
        }

        
private void LayoutRoot_Loaded(object sender, RoutedEventArgs e)
        {
            GetUser();
        }
      
    }
    
}

 

WebService中仅包含一个返回List<User>的GetUser();

PS:在Silverlight中并不包含DataGrid,如需使用,请引用System.Windows.Controls.Data

并且在Page.xaml中声明

xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data"
