这是一个简单的工作示例，其中 BindingNavigator GUI控件通过将 BindingSource对象的DataSource设置为IListSource的自定义子类来使用它来识别分页符。（感谢关键人物的回答。）当用户单击“下一页”按钮时，将触发BindingNavigator，bindingSource1_CurrentChanged并且您的代码可以获取所需的记录。说明：

1. 创建Windows窗体应用程序
2. 将BindingNavigator，DataGridView和BindingSource拖到窗体上

3. 用以下代码替换Form1.cs：

   using System;
   using System.Collections.Generic;
   using System.Windows.Forms;

   namespace PagedDataGridView
   {
   public partial class Form1 : Form
   {
   private const int totalRecords = 43;
   private const int pageSize = 10;

       public Form1()
       {
           InitializeComponent();
           dataGridView1.Columns.Add(new DataGridViewTextBoxColumn { DataPropertyName = "Index" });
           bindingNavigator1.BindingSource = bindingSource1;
           bindingSource1.CurrentChanged += new System.EventHandler(bindingSource1_CurrentChanged);
           bindingSource1.DataSource = new PageOffsetList();
       }
   
       private void bindingSource1_CurrentChanged(object sender, EventArgs e)
       {
           // The desired page has changed, so fetch the page of records using the "Current" offset 
           int offset = (int)bindingSource1.Current;
           var records = new List<Record>();
           for (int i = offset; i < offset + pageSize && i < totalRecords; i++)
               records.Add(new Record { Index = i });
           dataGridView1.DataSource = records;
       }
   
       class Record
       {
           public int Index { get; set; }
       }
   
       class PageOffsetList : System.ComponentModel.IListSource
       {
           public bool ContainsListCollection { get; protected set; }
   
           public System.Collections.IList GetList()
           {
               // Return a list of page offsets based on "totalRecords" and "pageSize"
               var pageOffsets = new List<int>();
               for (int offset = 0; offset < totalRecords; offset += pageSize)
                   pageOffsets.Add(offset);
               return pageOffsets;
           }
       }
   }
   

   }
