public:

public bool IsSelected { get; }
member this.IsSelected : bool
Public ReadOnly Property IsSelected As Boolean

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the ListView.VirtualItemsSelectionRangeChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type ListView named ListView1. Then ensure that the event handler is associated with the ListView.VirtualItemsSelectionRangeChanged event.

private void ListView1_VirtualItemsSelectionRangeChanged(Object sender, ListViewVirtualItemsSelectionRangeChangedEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "EndIndex", e.EndIndex );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "IsSelected", e.IsSelected );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "StartIndex", e.StartIndex );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "VirtualItemsSelectionRangeChanged Event" );
}
Private Sub ListView1_VirtualItemsSelectionRangeChanged(sender as Object, e as ListViewVirtualItemsSelectionRangeChangedEventArgs) _ 
     Handles ListView1.VirtualItemsSelectionRangeChanged

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "EndIndex", e.EndIndex)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "IsSelected", e.IsSelected)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "StartIndex", e.StartIndex)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"VirtualItemsSelectionRangeChanged Event")

End Sub

Remarks

The ListViewVirtualItemsSelectionRangeChangedEventArgs occurs when items are changed from selected to deselected, and deselected to selected. The isSelected parameter indicates the current state of the range of items.
