We will know when we select any row of a datagridview all records related will be displayed in the textboxes.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Data.OleDb;
namespace Datagridview_select_textbox_data
{
    public partial class Form1 : Form
    {
        string ConnectionString = System.Configuration.ConfigurationSettings.AppSettings["dsn"];
        OleDbCommand com;
        OleDbDataAdapter oledbda;
        string str;

        DataSet ds;
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            bindgrid();
        }
        private void bindgrid()
        {
            OleDbConnection con = new OleDbConnection(ConnectionString);
            con.Open();
            str = "select * from employee";
            com = new OleDbCommand(str, con);
            oledbda = new OleDbDataAdapter(com);
            ds = new DataSet();
            oledbda.Fill(ds, "employee");
            dataGridView1.DataMember = "employee";
            dataGridView1.DataSource = ds;
            con.Close();
        }

        private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            int i;
            i = dataGridView1.SelectedCells[0].RowIndex;
            txt_sno.Text = dataGridView1.Rows[i].Cells[1].Value.ToString();
            txt_name.Text = dataGridView1.Rows[i].Cells[2].Value.ToString();
            txt_address.Text = dataGridView1.Rows[i].Cells[3].Value.ToString();
            txt_age.Text = dataGridView1.Rows[i].Cells[4].Value.ToString();
     
            
        }
    }
}

            con.Open();
            str = "select * from employee";
            com = new OleDbCommand(str, con);
            oledbda = new OleDbDataAdapter(com);
            ds = new DataSet();
            oledbda.Fill(ds, "employee");
            dataGridView1.DataMember = "employee";
            dataGridView1.DataSource = ds;
            con.Close();
        }

        private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
        {
            
            DataGridViewRow row = dataGridView1.Rows[e.RowIndex];
            txt_sno.Text = row.Cells[0].Value.ToString();
            txt_name.Text = row.Cells[1].Value.ToString();
            txt_address.Text = row.Cells[2].Value.ToString();
            txt_age.Text = row.Cells[3].Value.ToString();
        }
    }
}

        }

        

        private void dataGridView1_RowHeaderMouseClick(object sender, DataGridViewCellMouseEventArgs e)
        {
            txt_sno.Text = dataGridView1.CurrentRow.Cells[0].Value.ToString();
            txt_name.Text = dataGridView1.CurrentRow.Cells[1].Value.ToString();
