    {
        public Form1()
        {
            InitializeComponent();

        DataSet ds = new DataSet();

        {
           
            string connectionString =
            @"Data Source=VENKAT\KAASHIV;Initial Catalog=wikitechy;
                user id = venkat;password=venkat";

            string sql = "SELECT * FROM login_table";

            SqlConnection connection = new SqlConnection(connectionString);

            SqlDataAdapter dataadapter = new SqlDataAdapter(sql, connection);

            connection.Open();
                        dataadapter.Fill(ds);
            connection.Close();

            dataGridView1.DataSource = ds.Tables[0];  

        }
      
        private void button2_Click(object sender, EventArgs e)
        {
            DataTable dataTable = (DataTable)dataGridView1.DataSource;
            DataRow drToAdd = dataTable.NewRow();

            drToAdd[0] = 4;
            drToAdd[1] = "jacob";

            dataTable.Rows.Add(drToAdd);
            dataTable.AcceptChanges();
            dataGridView1.DataSource = dataTable;
        }
    }
}

         
        

Code Explanation:

Here DataTable dataTable = (DataTable) dataGridView1. DataSource; specifies to dataTable can stores the rows and columns of data.
Here DataRow drToAdd = dataTable.NewRow(); specifies to Creates a new DataRow with the same schema as the table.
Here in this example drToAdd[0] = 4; specifies to add the four rows in the dataTable.
Here in this example drToAdd[1] = "jacob"; specifies to add Jacob new row in the DataTable.
Here dataTable.Rows.Add(drToAdd); specifies to new row is add to DataTable.
Here dataTable.AcceptChanges(); specifies to Commits all the changes complete to this table, then the last time AcceptChanges was called.
Here dataGridView1.DataSource = dataTable; used to specify the data source of datagridview and the table which will be bind to. When we run the code a window will show with a datagridview that containing all the returning rows.

Sample Output

Here in this output the Fetch Data button will display the data values from the SQL and displays it by clicking it.
Here in this output table displays the Id "1,2,3" and name "venkat, jln, arun".

Here in this output table displays the Id "1,2,3,4" and name "venkat, jln, arun, jacob".
Here in this output we display Add Row, which is add the new row "jacob" in the DataTable.
