คือว่าผมต้องการนำ data จาก Datagridview ไปใส่ใน sql server ซึ่งผม code ดังนี้       


Dim connectionString As String = "Data Source=kitiwat\SQLEXPRESS;Initial Catalog=mydatabase;Persist Security Info=True;User ID=sa;Password=1234"
        Dim sql As String = "SELECT * FROM ReAs"
        Dim connection As New SqlConnection(connectionString)
        Dim dataadapter As New SqlDataAdapter(sql, connection)
        Dim ds As New DataSet()
        connection.Open()
        dataadapter.Fill(ds, "ReAs")
        connection.Close()
        DataGridView1.DataSource = ds
        DataGridView1.DataMember = ("ReAs")
        Dim iRowsInserted As Int32 = DataGridView1.Update(ds, sql)
        MessageBox.Show("Data Saved")


แต่มันขึ้น error ว่า
Error    2    Too many arguments to 'Public Sub Update()'.
