前台界面

后台代码

//按钮事件
void saveButton_Click(object sender,RoutedEventArgs E)
{
    if (userName.Text.Trim() == String.Empty)
    {
        errmessage.Foreground = new SolidColorBrush(Colors.Red);
        errmessage.Text = "请输入用户名称！";
        errmessage.Visibility = Visibility.Visible;
        return;
    }
    //调用Webservice
    WebserviceProxy.UseRMANageSoapClient userMgrSoapClient =
        new YJingLee.WebSrv.WebserviceProxy.UseRMANageSoapClient();
    //创建用户操作
    userMgrSoapClient.CreateUserAsync(userName.Text);
    userMgrSoapClient.CreateUserCompleted += 
        new EventHandler<YJingLee.WebSrv.WebserviceProxy.
            CreateUserCompletedEventArgs>
            (userMgrSoapClient_CreateUserCompleted);
}
void userMgrSoapClient_CreateUserCompleted(object sender,YJingLee.WebSrv.WebserviceProxy.CreateUserCompletedEventArgs E)
{
    if (e.Error == null)
    {
        errmessage.Text = "创建用户成功！";
        errmessage.Foreground = new Colors.bluE);
        errmessage.Visibility = Visibility.Visible;
    }
    else
    {
        errmessage.Foreground = new Colors.Red);
        errmessage.Text = e.Error.ToString();
        errmessage.Visibility = Visibility.Visible;
    }
}

查询数据部分

我们使用Silverlight 2自带的DataGrid控件绑定数据。前台非常简单，只是一个DataGrid控件，但是前段时间有的同学问DataGrid控件不知怎么弄进来。这里详细说明一下。

第一步：在Silverlight工程中添加引用

第二步：查找System.Windows.Controls.Data程序集，添加进来

第三步：在UserControl中添加这个引用，有智能感知。我将其命名为Data。

在前台编写代码如下

<Button x:Name="reButton" Content="刷新"
        Width="50" Height="30" Grid.Row="0"></Button>
<Data:DataGrid x:Name="userDataGrid" Height="200" 
               Width="700" @H_68_115@margin="0,5,10"
              AutoGeneratecolumns="True" 
               VerticalAlignment="Top" Grid.Row="1">
</DataGrid>

//显示数据 void LisTingControlDisplay(object sender,175)">RoutedEventArgs E) { WebserviceProxy.UseRMANageSoapClient(); userMgrSoapClient.RetrieveUsersAsync(); userMgrSoapClient.RetrieveUsersCompleted += new RetrieveUsersCompletedEventArgs> (userMgrSoapClient_RetrieveUsersCompleted); } void userMgrSoapClient_RetrieveUsersCompleted(object sender,175)">RetrieveUsersCompletedEventArgs E) { if (e.Error == null) displayData(e.Result); } private void displayData(String xmlContent) { try { if (xmlContent != String.Empty) { XDocument xmlUsers = XDocument.Parse(xmlContent); var users = from user in xmlUsers.Descendants("User") SELEct new { UserID = Convert.ToInt32 (user.Element("UserID").value),UserName = (String) user.Element("UserName").Value }; List<User> usersList = new User>(); foreach (var u in users) { User use = new User { UserID = u.UserID,UserName = u.UserName }; usersList.Add(usE); } userDataGrid.Itemssource = usersList; } else { userDataGrid.Itemssource = null; } } catch (Exception eX) { Console.Write(ex.messagE); } } public class User { public int UserID { get; set; } public String UserName { get; set; } }

修改数据部分

void updateButton_Click(object sender,175)">RoutedEventArgs E) { if (userID.Text.Trim() == String.Empty) { errmessage.Foreground = new "请输入用户ID！"; errmessage.Visibility = Visibility.Visible; return; } if (userName.Text.Trim() == String.Empty) { errmessage.Foreground = new Visibility.Visible; return; } WebserviceProxy.UseRMANageSoapClient(); //调用更新用户方法 userMgrSoapClient.updateUserAsync (Int16.Parse(userID.Text.Trim()),userName.Text.Trim()); userMgrSoapClient.updateUserCompleted += new updateUserCompletedEventArgs> (userMgrSoapClient_updateUserCompleted); } void userMgrSoapClient_updateUserCompleted(object sender,175)">updateUserCompletedEventArgs E) { if (e.Error == null) { errmessage.Text = "修改用户成功！"; errmessage.Foreground = new 删除数据部分

void deleteButton_Click(object sender,175)">UseRMANageSoapClient

deleteCtl.Visibility = Visibility.Visible;
entryCtl.Visibility = Visibility.Collapsed;
lisTingCtl.Visibility = Visibility.Collapsed;
editCtl.Visibility = Visibility.Collapsed;
