How to Add Items to Multiple Columns in a C# ListView Control?

Adding Items to Multiple Columns in a ListView Control (C#)?

When working with a ListView control in a WinForms application, you may encounter the need to populate multiple columns within each row. This article delves into several methods for achieving this using the 'ListViewItem' class and its 'SubItems' property.

Method 1: Using the 'SubItems.AddRange' Method

For a concise approach, you can utilize the 'SubItems.AddRange' method to add items to multiple columns simultaneously.

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

Method 2: Using the 'SubItems.Add' Method

Alternatively, you can use the 'SubItems.Add' method to add items to individual columns more explicitly.

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

Method 3: Using an Array of 'ListViewItem' Objects

If you prefer to create 'ListViewItem' objects manually, you can populate them with subitems and then add them to the 'ListView' using 'AddRange'.

ListViewItem[] items = new ListViewItem[] {
    new ListViewItem("Something1") { SubItems = { "a", "b", "c" } },
    new ListViewItem("Something2") { SubItems = { "d", "e", "f" } }
};

listView1.Items.AddRange(items);
