DataGridView1 が、(1) の直接 Rows.Add。
DataGridView2 が、(2) のデータバインド法です。

Imports System.ComponentModel
Public Class Form1
    Private tbl As DataTable

Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
        DataGridView1.ColumnCount = 4
        DataGridView1.Rows.Add("1-1", "1-2", "1-3", "1-4")
        DataGridView1.Rows.Add("2-1", "2-2", "2-3", "2-4")
        DataGridView1.Rows.Add("8-1", "8-2", "8-3", "8-4")
        DataGridView1.Rows.Add("3-1", "3-2", "3-3", "3-4")
        DataGridView1.Sort(DataGridView1.Columns(0), ListSortDirection.Ascending)

tbl = New DataTable()
        tbl.Columns.Add("Col1")
        tbl.Columns.Add("Col2")
        tbl.Columns.Add("Col3")
        tbl.Columns.Add("Col4")
        DataGridView2.AutoGenerateColumns = True
        DataGridView2.DataSource = tbl
        tbl.Rows.Add("1-1", "1-2", "1-3", "1-4")
        tbl.Rows.Add("2-1", "2-2", "2-3", "2-4")
        tbl.Rows.Add("8-1", "8-2", "8-3", "8-4")
        tbl.Rows.Add("3-1", "3-2", "3-3", "3-4")
        DataGridView2.Sort(DataGridView2.Columns(0), ListSortDirection.Ascending)
    End Sub

Private Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click
        DataGridView1.Rows.Add("0-1", "0-2", "0-3", "0-4")
    End Sub

Private Sub Button2_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button2.Click
        tbl.Rows.Add("0-1", "0-2", "0-3", "0-4")
    End Sub
End Class
