Gets or sets a value indicating whether multiple items can be selected.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
When the property is set to true, multiple items can be selected in the ListView control. To select multiple items, the user must hold down the CTRL key while clicking the items to select. Consecutive items can be selected by clicking the first item to select and then, while holding down the SHIFT key, clicking the last item to select. You can use the multiple selection feature to select multiple items in the ListView control and perform an operation on all the items selected. For example, the user could select multiple items and then right-click a selected item to display a shortcut menu that displays a set of tasks that can be performed on the selected items.
To determine which items are selected in the ListView control, use the SelectedItems property. The SelectedItems property allows you to access the ListView.SelectedListViewItemCollection that contains a list of the selected items. If you want the index positions in the ListView.ListViewItemCollection instead of the items, you can use the SelectedIndices property to access the ListView.SelectedIndexCollection.
If you do not want to allow multiple selections in the ListView, yet still want to offer the user a way for multiple items to be chosen, you can display check boxes by setting the CheckBoxes property to true.
The following code example demonstrates a ListView that allows multiple items to be selected. The example demonstrates setting the HideSelection and HeaderStyle properties. 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.
