Adding items to a listview in C#

Before adding items to a listview, set the listview’s View property to Detail.  This allows the definition of multiple columns.

Now, the individual columns can now be defined.  In this example, I will create and use a 4-column listview.  To create the listview, use the Columns property and define the Name and Text.

Column Definition

Defining all four columns creates this listview:

Listview and properties

Each row in the listview is a ListViewItem.  Each column in a ListViewItem is a SubItem.  Each SubItem is added to each ListViewItem in the order the columns are defined.

These are the steps taken to add multiple ListViewItems (or rows) to a listview:

1. Notify the listView control that an update is about to begin
2. Clear any existing listViewItems
3. Create an individual ListViewItem
4. Add the subItems
5. Notify the listView control that the update has ended
6. Notifi the listView control to refresh itself so that it will display the new rows

 int i = 1;
 lstXmlItems.BeginUpdate();
 lstXmlItems.Items.Clear();

 foreach (var item in bools)
 {
      ListViewItem row = new ListViewItem(i.ToString());
      row.SubItems.Add(item.EventId);
      row.SubItems.Add(item.Name);
      row.SubItems.Add(item.WordPos);
      lstXmlItems.Items.Add(row);
      i++;
 }
lstXmlItems.EndUpdate();
lstXmlItems.Refresh();
