        }
        
        private void button1_Click(object sender, EventArgs e)
        {
            
            using (SqlCommand cmd = new SqlCommand("Insert into Emp_Details   (Emp_ID,Name,Education) values (" + textBox2.Text + ",'" + textBox3.Text + "','" + textBox1.Text + "')", con))
            {
                cmd.ExecuteNonQuery();
            }
            FillData();
        }

        private void textBox2_TextChanged(object sender, EventArgs e)
        {

        }
    
    
     void FillData()
        {
            
                using (SqlDataAdapter a = new SqlDataAdapter("SELECT * FROM Emp_Details", con))
                {
                    DataTable t = new DataTable();
                    a.Fill(t);
                    dataGridView1.DataSource = t;
                }
            
        }
    }
}

Using this code i can able to enter the data in textboxes, it will automatically populated in grid view.
Now i want when i click on particular row in grid view the data must populate in text boxes.


Can any one help me to solve this issue.

Thanks.
