新建Custom Control，名：PagingDataGrid
打开工程下面的ThemesGeneric.xaml
xaml里面代码替换如下

打开PagingDataGrid.cs文件

此外还需要一个类支持PagingChangedEventArgs
1 /// <summary> 2 /// 页跳转参数 3 /// </summary> 4 public class PagingChangedEventArgs : EventArgs 5 { 6 public int PageSize { get; set; } 7 public int PageIndex { get; set; } 8 }
控件完成，调试：

新建调试类Student
1 public class Student 2 { 3 public string Name { get; set; } 4 public int Age { get; set; } 5 public string MoreInfo { get; set; } 6 }
调试代码，注意这里使用DataItems保存信息，如果使用Items或是ItemsSource则无分页效果
1 List<Student> list = new List<Student>(); 2 for (int i = 0; i < 20; i++) 3 { 4 list.Add(new Student() { Name = Guid.NewGuid().ToString(), Age = i, MoreInfo = "Sex" }); 5 } 6 pdg.DataItems = list;
