Filling up a listview dynamically with file contents

[VM]

How can I fill up a listview with text file contents?
My listview has two columns and the first column fills up with a while loop:

while (myString != null)
{
myString = sr.Readline();
listView1.Items .Add (myString);
}

Is there a way I can fill up the second column this easily? Thw way I'm currently doing it is using the subitems property to add it. Unfortunately,
I'm using a counter to tell it which line to fill up and adding to the second column is directly related to the first item (eg. I can't add a subitem on the 2nd column unlee I have added one in the 1st column).

Also, the MSDN sample doesn't work correctly. In the following code from MSDN, if I copy/paste it'll work perfectly. But if I comment the first line so it uses the listView I created in the designer (instead of creating a new one), it doesn't have the same effect.

// ListView listView1 = new ListView(); /* Commented so it uses existing listView1 */
listView1.Bound s = new Rectangle(new Point(10,10), new Size(300,200));
listView1.View = View.Details;
ListViewItem item1 = new ListViewItem("i tem1",0);
item1.Checked = true;
item1.SubItems. Add("1");
item1.SubItems. Add("2");
item1.SubItems. Add("3");
ListViewItem item2 = new ListViewItem("i tem2",1);
item2.SubItems. Add("4");
item2.SubItems. Add("5");
item2.SubItems. Add("6");
listView1.Colum ns.Add("Item Column", -2, HorizontalAlign ment.Left);
listView1.Colum ns.Add("Column 2", -2, HorizontalAlign ment.Left);
listView1.Items .AddRange(new ListViewItem[]{item1,item2});
this.Controls.A dd(listView1);

Thanks.
