How can we do pagination in datagridview in winform

by

Here’s a simple working example, where a
BindingNavigator GUI control uses a
BindingSource object to
identify page breaks, by setting its DataSource to a custom subclass of IListSource.
(Thanks to this answer for
the key idea.) When the user clicks the “next page” button, the BindingNavigator fires bindingSource1_CurrentChanged and your code can fetch the desired records. Instructions:

  1. Create a Windows Forms application
  2. Drag onto the form a BindingNavigator, a DataGridView, and a BindingSource
  3. Replace Form1.cs with the following code:
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;
            }
        }
    }
}
