Answer 1

ListViewItem item = new ListViewItem();
item.Text = "fdfdfd";
item.SubItems.Add ("melp");
listView.Items.Add(item);

Answer 2

You whack the subitems into an array and add the array as a list item.

The order in which you add values to the array dictates the column they appear under so think of your sub item headings as [0],[1],[2] etc.

Here's a code sample:

//In this example an array of three items is added to a three column listview
string[] saLvwItem = new string[3];

foreach (string wholeitem in listofitems)
{
     saLvwItem[0] = "Status Message";
     saLvwItem[1] = wholeitem;
     saLvwItem[2] = DateTime.Now.ToString("ffffdd dd/MM/yyyy - HH:mm:ss");

     ListViewItem lvi = new ListViewItem(saLvwItem);

     lvwMyListView.Items.Add(lvi);
}

Answer 3

Suppose you have a List Collection containing many items to show in a ListView, take the following example that iterates through the List Collection:

foreach (Inspection inspection in anInspector.getInspections())
  {
    ListViewItem item = new ListViewItem();
    item.Text=anInspector.getInspectorName().ToString();
    item.SubItems.Add(inspection.getInspectionDate().ToShortDateString());
    item.SubItems.Add(inspection.getHouse().getAddress().ToString());
    item.SubItems.Add(inspection.getHouse().getValue().ToString("C"));
    listView1.Items.Add(item);
  }

That code produces the following output in the ListView (of course depending how many items you have in the List Collection):

Basically the first column is a listviewitem containing many subitems (other columns). It may seem strange but listview is very flexible, you could even build a windows-like file explorer with it!

Answer 4

add:

.SubItems.Add("asdasdasd");

to the last line of your code so it will look like this in the end.

listView1.Items.Add("sdasdasdasd").SubItems.Add("asdasdasd");
