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

Adding Items to Multiple Columns in a ListView Control

Adding items to the first column of a ListView control is straightforward using listView1.Items.Add. However, to add items to subsequent columns, a slightly different approach is required.

Solution 1

Using the SubItems property of the ListViewItem, you can add items to specific columns. For instance, to add items to the first four columns:

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

Solution 2

Alternatively, you can create individual ListViewItem objects for each row and add subitems using SubItems.Add:

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});

These solutions provide flexibility in adding items to multiple columns in a ListView control, allowing for dynamic data population.
