I'm starting to doing it by myself. It isn't as hard as I thought it will be.

using (System.IO.StreamReader sr = new System.IO.StreamReader(@"c:\data.txt"))
{
    sr.BaseStream.Position = 5; // byte number 5 NOT line number 5
    sr.Read(); // to fill the buffer
    MessageBox.Show(sr.ReadLine());
}

string[] lines = System.IO.File.ReadAllLines(@"c:\data.txt");

dataGridView1.SelectedCells = null;

dataGridView1.SelectedRows = null;

DGV.ClearSelection();
