ListView.SelectedItems Property

Gets the items that are selected in the control.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public SelectedListViewItemCollection SelectedItems { get; }
/** @property */
public SelectedListViewItemCollection get_SelectedItems ()

public function get SelectedItems () : SelectedListViewItemCollection

Property Value

A ListView.SelectedListViewItemCollection that contains the items that are selected in the control. If no items are currently selected, an empty ListView.SelectedListViewItemCollection is returned.

The SelectedItems property will not contain any items if the property is accessed before the ListView handle is created, which typically occurs when ListView is initially loaded for display in the form. You can check to see if the handle is created with the IsHandleCreated property. When the MultiSelect property is set to true, this property returns a collection containing the items that are selected in the ListView. For a single-selection ListView, this property returns a collection containing the only selected item in the ListView. For more information on the tasks that can be performed with the items in the collection, see ListView.SelectedListViewItemCollection.

If you want to obtain a collection of the index positions within the ListView.ListViewItemCollection of the items that are selected in the ListView control, instead of the items that are selected, use the SelectedIndices property.

The following code example demonstrates using the SelectedItems, SelectedIndexChanged event, and HeaderStyle members and the ListView.SelectedListViewItemCollection class. To run this example, paste the following code into a form that contains a ListView object named ListView1 and a TextBox named TextBox1. Call the InitializeListView method from the form's constructor or Load method. This example requires the event handler is correctly associated with the SelectedIndexChanged event

	// This method adds two columns to the ListView, setting the Text 
	// and TextAlign, and Width properties of each ColumnHeader.  The 
	// HeaderStyle property is set to NonClickable since the ColumnClick 
	// event is not handled.  Finally the method adds ListViewItems and 
	// SubItems to each column.
	private void InitializeListView()

	 	ColumnHeader columnHeader2 = new ColumnHeader();
		columnHeader2.Text = "Price Each";
