    <p>So most things ive read about loading textfiles in windows form shows you loading it into a single dimension string array. but I have some features id like to do that would work much better if it were a two dimensional array. in this example i have a book catalog with isbn, author, title, year, price. I want to be able to compile data about most expensive and least expensive book (which I'm able to do already from the array that i have for user entry), and be able to search the array by title, isbn, etc. I also am displaying it in a multicolumn listview. </p> <p>Heres what I have for loading the textfile (which is new records separated by new lines, and it is tab ('\t') delimited) and displaying it in the multicolumn listview. What would I need to do to load this into a 2D array? and how would i display it? any help would be great.</p> <pre><code>static FileStream textFile = new FileStream("booklist.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite); StreamReader reader = new StreamReader(textFile); StreamWriter writer = new StreamWriter(textFile); const char DELIM = '\t'; //string[] booksTextArray; string line = ""; string[] items; ListViewItem listItem; // the load button private void LoadButton_Click(object sender, EventArgs e) { // loads text file with existing book catalog while((line = reader.ReadLine()) != null) { items = line.Split('\t'); //Split the line. listItem = new ListViewItem(); //"Row" object. for (int i = 0; i &lt; items.Length; i++) { if (i == 0) { listItem.Text = items[i]; //First item is not a "subitem". } else { listItem.SubItems.Add(items[i]); //Add it to the "Row" object. } } listView1.Items.Add(listItem); //Add the row object to the listview. status_label.Text = "Load successful."; } } </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.
