C#: How to add subitems in ListView
Solution 1
Like this:
ListViewItem lvi = new ListViewItem();
lvi.SubItems.Add("SubItem");
listView1.Items.Add(lvi);
Solution 2
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!

I think the quickest/neatest way to do this:
For each class have string[] obj.ToListViewItem()
method and then do this:
foreach(var item in personList)
{
listView1.Items.Add(new ListViewItem(item.ToListViewItem()));
}
Here is an example definition
public class Person
{
public string Name { get; set; }
public string Address { get; set; }
public DateTime DOB { get; set; }
public uint ID { get; set; }
public string[] ToListViewItem()
{
return new string[] {
ID.ToString("000000"),
Name,
Address,
DOB.ToShortDateString()
};
}
}
As an added bonus you can have a static
method that returns ColumnHeader[]
list for setting up the listview columns with
listView1.Columns.AddRange(Person.ListViewHeaders());

I've refined this using an extension method on the ListViewItemsCollection. In my opinion it makes the calling code more concise and also promotes more general reuse.
internal static class ListViewItemCollectionExtender
{
internal static void AddWithTextAndSubItems(
this ListView.ListViewItemCollection col,
string text, params string[] subItems)
{
var item = new ListViewItem(text);
foreach (var subItem in subItems)
{
item.SubItems.Add(subItem);
}
col.Add(item);
}
}
Calling the AddWithTextAndSubItems looks like this:
// can have many sub items as it's string array
myListViewControl.Items.AddWithTextAndSubItems("Text", "Sub Item 1", "Sub Item 2");
Hope this helps!
Solution 5
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");

P. Duw almost 4 years
Creating an item(Under the key) is easy,but how to add subitems(Value)?
listView1.Columns.Add("Key"); listView1.Columns.Add("Value"); listView1.Items.Add("sdasdasdasd"); //How to add "asdasdasd" under value?
