   在Silverlight Toolkit 3.0中提供了强大灵活的数据分页控件：DataPager。并且其还有多种显示样式 (DisplayMode) 供使用。终于可以不用再自己费神巴力去实现分页功能了，下面是其演示效果：
  [http://daizhj.cnblogs.com/images/cnblogs_com/daizhj/sl_toolkit_datapager.gif]
  接着介绍一下其使用方法。
  
  　 　首先，我们要新建一个Silverlight应用，并添加对下面DLL的引用：
  
   System.Windows.Data（其提供了PagedCollectionView类用于实现分页绑定）
  　　
  　　System.Windows.Controls.Data（分页器控件DataPager所在DLL）
  　　
  　　 XAML文件头部名空间声明：
  
  xmlns:data=”clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data”
  　　
  　　然后我们要在当前XAML中放置一个DataGrid用于显示列表数据，声明如下：
  
  <data:DataGrid x:Name=”MyDataGrid” Grid.Column=”0″ Grid.Row=”0″ ItemsSource=”{Binding}” />
  　　
  　　为了演示不同显示样式(DisplayMode)的效果，下面根据其样式分别加以声明：
  
  <data:DataPager x:Name =”FirstLastNumeric” Grid.Row=”2″ DisplayMode=”FirstLastNumeric” Margin=”0,0,0,4″
   HorizontalAlignment=”Left” Source=”{Binding}” NumericButtonCount=”3″ AutoEllipsis=”True”/>
  
  <data:DataPager x:Name =”FirstLastPreviousNext” Grid.Column=”0″ Grid.Row=”3″ DisplayMode=”FirstLastPreviousNext”
   Margin=”0,0,0,4″ HorizontalAlignment=”Left” Source=”{Binding}” NumericButtonCount=”3″ AutoEllipsis=”True”/>
  
  <data:DataPager x:Name =”FirstLastPreviousNextNumeric” Grid.Column=”0″ Grid.Row=”4″ DisplayMode=”FirstLastPreviousNextNumeric”
   Margin=”0,0,0,4″ HorizontalAlignment=”Left” Source=”{Binding}” NumericButtonCount=”4″ AutoEllipsis=”True”/>
  
  <data:DataPager x:Name =”Numeric” Grid.Column=”0″ Grid.Row=”5″ DisplayMode=”Numeric” HorizontalAlignment=”Left”
   Margin=”0,0,0,4″ Source=”{Binding}” NumericButtonCount=”6″ AutoEllipsis=”False”/>
  
  <data:DataPager x:Name =”PreviousNext” Grid.Column=”0″ Grid.Row=”6″ DisplayMode=”PreviousNext” Margin=”0,0,0,4″
   HorizontalAlignment=”Left” Source=”{Binding}” NumericButtonCount=”3″ AutoEllipsis=”False” />
  
  <data:DataPager x:Name =”PreviousNextNumeric” Grid.Column=”0″ Grid.Row=”7″ DisplayMode=”PreviousNextNumeric” Margin=”0,0,0,4″
   HorizontalAlignment=”Left” Source=”{Binding}” NumericButtonCount=”4″ AutoEllipsis=”False” />
  
   好了，为了便于演示，我“硬编码”了一个数据对象集合如下：
  
  public List<EmployeeInfo> GetEmployeeList()
   {
   List<EmployeeInfo> employeeList = new List<EmployeeInfo>();
   employeeList.Add(new EmployeeInfo { EmployeeID = 1, EmployeeName = “大林”, Salary = 1000, City = “合肥” });
   employeeList.Add(new EmployeeInfo { EmployeeID = 2, EmployeeName = “小林”, Salary = 1000, City = “合肥” });
   employeeList.Add(new EmployeeInfo { EmployeeID = 3, EmployeeName = “张三”, Salary = 1000, City = “合肥” });
   employeeList.Add(new EmployeeInfo { EmployeeID = 4, EmployeeName = “李四”, Salary = 1500, City = “天津” });
   employeeList.Add(new EmployeeInfo { EmployeeID = 5, EmployeeName = “王五”, Salary = 2000, City = “上海” });
   employeeList.Add(new EmployeeInfo { EmployeeID = 6, EmployeeName = “赵六”, Salary = -800, City = “北京” });
   employeeList.Add(new EmployeeInfo { EmployeeID = 7, EmployeeName = “尤七”, Salary = 2100, City = “武汉” });
   employeeList.Add(new EmployeeInfo { EmployeeID = 8, EmployeeName = “马八”, Salary = 2300, City = “海口” });
   employeeList.Add(new EmployeeInfo { EmployeeID = 9, EmployeeName = “许九”, Salary = 2300, City = “海口” });
   employeeList.Add(new EmployeeInfo { EmployeeID = 10, EmployeeName = “代十”, Salary = 2300, City = “海口” });
   return employeeList;
   }
  
   public class EmployeeInfo
   {
   public int EmployeeID { set; get; }
   public string EmployeeName { set; get; }
   public int Salary { set; get; }
   public int[] Cost { get; set; }
   public string City { set; get; }
   }
  
   接下来就是如何实现分页，以及相关控件的数据绑定了，代码位于MyDataPager.xaml.cs（详见注释）：
  
  using System.Windows.Data;
  
  
  public MyDataPager()
  {
   InitializeComponent();
   PagedCollectionView pcv = new PagedCollectionView(GetEmployeeList());
   pcv.PageSize = 3;//一页显示三条记录
  
   //列表控件数据源绑定
   MyDataGrid.DataContext = pcv;
   MyListBox.DataContext = pcv;
  
   //分页控件数据源绑定
   FirstLastNumeric.DataContext = pcv;
   FirstLastPreviousNext.DataContext = pcv;
   FirstLastPreviousNextNumeric.DataContext = pcv;
   Numeric.DataContext = pcv;
   PreviousNext.DataContext = pcv;
   PreviousNextNumeric.DataContext = pcv;
  }
  
   是不是很好用，呵呵。当然该控件还提供了NumericButtonCount属性用于控制页码的数量，这在上面的XAML控件声明时已使用，大家可以修改测试一下效果。
  
  　　好的，今天的内容就先到这里了。
