Listview - adding data

So, trying to use the ListView and fill it with data.

ListViewItem item = new ListViewItem("Test");
item.SubItems.Add("1");
item.SubItems.Add("2");
MyListView.Items.Add(item);

Now, I haven been searching and reading and I feel so stupid cause I just can't figure out how the items/subitems work.

The above code won't do anything :/

       foreach (Ingredient o in list)
        {
            ListViewItem lvi = new ListViewItem();

            lvi.Text = o.iName;
            lvi.SubItems.Add(o.iUnit);
            lvi.SubItems.Add(Convert.ToString(o.iCalories));
            listView1.Items.Add(lvi);

        }

It works now, BUT, I no longer have access to the items. How do I know get back an item, or change stuff in an item?

listView1.Items.Clear();
        listView1.View = View.Details;

        List<Ingredient> list = controller.FindAllIngredients();

        foreach (Ingredient o in list)
        {
            ListViewItem lvi = new ListViewItem();

            lvi.Text = o.iName;
            lvi.SubItems.Add(o.iUnit);
            lvi.SubItems.Add(Convert.ToString(o.iCalories));
            listView1.Items.Add(lvi);

        }

How do I make this into a generic method that doesn't have to know the number of fields. For example, if i added another field, Category to Ingridient this method wouldn't work. Would also like to use it for all my listviews, independ on the class and number of columns.

This should work:

viewList.View = View.Details;

viewList.Columns.Add("Key");
viewList.Columns.Add("Value");

ListViewItem lvi1 = new ListViewItem();

lvi1.Text = "Key";
lvi1.SubItems.Add("Value");
viewList.Items.Add(lvi1);

In your ListView control, you need to set the View style to Details if you want to see the SubItems.

Example:
