    <p>I am trying to follow along and complete this address book tutorial on YouTube <a href="http://www.youtube.com/watch?v=0ZoDmeAZAD8&amp;feature=relmfu" rel="nofollow">Address Book Tutorial</a></p> <p>But I have ran into a snag that I don't understand. Following along I cannot find the difference in code. So I am thinking it must be a property setting that I am missing. When I test populate the list I can select the first item. But when I select the second item the debugger kicks out an error </p> <blockquote> <p>invalid argument=value of '0' is not valid for 'index'</p> </blockquote> <p>Can someone tell me why this error is thrown? Listening to the video it sounds like the 0 in the code is to tell the list that you can only select one item at a time. Unfortunately I haven't been able to figure out why his code works and mine does not. </p> <pre><code>private void button3_Click(object sender, EventArgs e) { person p = new person(); // creates new string array p.Name = textBox1.Text; // name p.StreetAddress= textBox3.Text; // address p.Email = textBox2.Text; // email p.Birthday = dateTimePicker1.Value; //birthday p.AdditionalNotes = textBox4.Text; // any notes people.Add(p); // tells the the above data to be added to the people list. listView1.Items.Add(p.Name); // makes its show on the listview of the main box. textBox1.Text = ""; textBox2.Text = ""; textBox3.Text = ""; textBox4.Text = ""; dateTimePicker1.Value = DateTime.Now; } private void listView1_SelectedIndexChanged(object sender, EventArgs e) { textBox1.Text = people[listView1.SelectedItems[0].Index].Name; //Debugger points error here. textBox2.Text = people[listView1.SelectedItems[0].Index].Email; textBox3.Text = people[listView1.SelectedItems[0].Index].StreetAddress; textBox4.Text = people[listView1.SelectedItems[0].Index].AdditionalNotes; dateTimePicker1.Value = people[listView1.SelectedItems[0].Index].Birthday; } class person { public string Name { get; set; } ... } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
