C#: How to add subitems in ListView

Question

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         


        

Answer 1

Create a listview item

ListViewItem item1 = new ListViewItem("sdasdasdasd", 0)
item1.SubItems.Add("asdasdasd")

Answer 2

Like this:

ListViewItem lvi = new ListViewItem();
lvi.SubItems.Add("SubItem");
listView1.Items.Add(lvi);

Answer 3

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());

Answer 4

Generally:

ListViewItem item = new ListViewItem("Column1Text")
   { Tag = optionalRefToSourceObject };

item.SubItems.Add("Column2Text");
item.SubItems.Add("Column3Text");
myListView.Items.Add(item);

Answer 5

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!

Great !! It has helped me a lot. I used to do the same using VB6 but now it is completely different. we should add this

listView1.View = System.Windows.Forms.View.Details;
listView1.GridLines = true; 
listView1.FullRowSelect = true;
