當 a ListView 處於虛擬模式且某一範圍的選取狀態改變時，會發生這種情況。

public:
 event System::Windows::Forms::ListViewVirtualItemsSelectionRangeChangedEventHandler ^ VirtualItemsSelectionRangeChanged;
public event System.Windows.Forms.ListViewVirtualItemsSelectionRangeChangedEventHandler VirtualItemsSelectionRangeChanged;
public event System.Windows.Forms.ListViewVirtualItemsSelectionRangeChangedEventHandler? VirtualItemsSelectionRangeChanged;
member this.VirtualItemsSelectionRangeChanged : System.Windows.Forms.ListViewVirtualItemsSelectionRangeChangedEventHandler 
Public Custom Event VirtualItemsSelectionRangeChanged As ListViewVirtualItemsSelectionRangeChangedEventHandler

範例

以下程式碼範例展示了此成員的使用方式。 在這個例子中，事件處理者會回報事件 VirtualItemsSelectionRangeChanged 的發生情況。 此報告能幫助您了解事件發生時間，並協助除錯。 若要報告多個事件或頻繁發生的事件，請考慮將MessageBox.Show訊息替換Console.WriteLine為或附加於多行TextBox。

要執行範例程式碼，請將其貼到包含一個 ListView 名為 ListView1的實例的專案中。 然後確保事件處理程式與事件 VirtualItemsSelectionRangeChanged 相關聯。

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
