public object Tag { get; set; }

Property Value

Type: System.Object

An object that contains information that is associated with the item.

The Tag property can be used to store any object that you want to associate with an item. Although you can store any item, the Tag property is typically used to store string information about the item, such as a unique identifier or the index position of the item's data in a database.

The following code example demonstrates how to initialize a ListViewItem and set the Tag and Text properties. To run this example, place the following code in a form that contains a ListView named ListView1, and call InitializeListViewItems from the form's constructor or Load event-handling method.

private void InitializeListViewItems()
	ListView1.View = View.List;

	Cursor[] favoriteCursors = new Cursor[]{Cursors.Help, 
		Cursors.Hand, Cursors.No, Cursors.Cross};

	// Populate the ListView control with the array of Cursors.
	foreach ( Cursor aCursor in favoriteCursors )

		// Construct the ListViewItem object
		ListViewItem item = new ListViewItem();

		// Set the Text property to the cursor name.
		item.Text = aCursor.ToString();

		// Set the Tag property to the cursor.
		item.Tag = aCursor;

		// Add the ListViewItem to the ListView.
