C# listView, how do I add items to columns 2, 3 and 4 etc?

Question

要在我的listView控件（ Winform ）中向第1列添加项目，我正在使用listView1.Items.Add ，这可以正常工作，但如何将项目添加到第2列和第3列等？

Answer 1

There are several ways to do it, but here is one solution (for 4 columns).

string[] row1 = { "s1", "s2", "s3" };
listView1.Items.Add("Column1Text").SubItems.AddRange(row1);

And a more verbose way is here:

ListViewItem item1 = new ListViewItem("Something");
item1.SubItems.Add("SubItem1a");
item1.SubItems.Add("SubItem1b");
item1.SubItems.Add("SubItem1c");

ListViewItem item2 = new ListViewItem("Something2");
item2.SubItems.Add("SubItem2a");
item2.SubItems.Add("SubItem2b");
item2.SubItems.Add("SubItem2c");

ListViewItem item3 = new ListViewItem("Something3");
item3.SubItems.Add("SubItem3a");
item3.SubItems.Add("SubItem3b");
item3.SubItems.Add("SubItem3c");

ListView1.Items.AddRange(new ListViewItem[] {item1,item2,item3});

You can add items / sub-items to the ListView like:

ListViewItem item = new ListViewItem(new []{"1","2","3","4"});
listView1.Items.Add(item);

But I suspect your problem is with the View Type . Set it in the designer to Details or do the following in code:

listView1.View = View.Details;

 private void MainTimesheetForm_Load(object sender, EventArgs e)
        {
            ListViewItem newList = new ListViewItem("1");
            newList.SubItems.Add("2");
            newList.SubItems.Add(DateTime.Now.ToLongTimeString());
            newList.SubItems.Add("3");
            newList.SubItems.Add("4");
            newList.SubItems.Add("5");
            newList.SubItems.Add("6");
            listViewTimeSheet.Items.Add(newList);

        }

Here is the msdn documentation on the listview object and the listviewItem object.
http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.aspx
http://msdn.microsoft.com/en-us/library/system.windows.forms.listviewitem.aspx

I would highly recommend that you at least take the time to skim the documentation on any objects you use from the .net framework. While the documentation can be pretty poor at some times it is still invaluable especially when you run into situations like this.

But as James Atkinson said it's simply a matter of adding subitems to a listviewitem like so:

ListViewItem i = new ListViewItem("column1");
i.SubItems.Add("column2");
i.SubItems.Add("column3");

Answer 5

For your problem use like this:

ListViewItem row = new ListViewItem(); 
row.SubItems.Add(value.ToString()); 
listview1.Items.Add(row);

Answer 6

我制作的一条线，它有效：

listView1.Items.Add(new ListViewItem { ImageIndex = 0, Text = randomArray["maintext"], SubItems = { randomArray["columntext2"], randomArray["columntext3"] } });

Answer 7

使用ListViewSubItem - 请参阅： MSDN
