SheetViewクラスのAddUnboundRowsメソッドで、データソースに非連結な行を追加します。ユーザーがデータを追加するための、未入力の新規行を表示する場合などに使用できます。ユーザーがデータを入力した後に、非連結な行をデータソースに追加するにはAddRowToDataSourceメソッドを使用します。
実行例：
非連結行を先頭に追加：
コンソール出力（デバッグメッセージ）：
| データソース行数：9 |
ユーザーが入力後、非連結行をデータソースに追加：
コンソール出力（デバッグメッセージ）：
| データソース行数：10 |
protected void Page_Load(object sender, EventArgs e) { if (IsPostBack) return; FpSpread1.DataSource = new StockList(); //非連結行を追加します FpSpread1.Sheets[0].AddUnboundRows(0, 1); System.Diagnostics.Debug.WriteLine(string.Format("データソース行数：{0}", ((StockList)FpSpread1.DataSource).Count)); } protected void Button1_Click(object sender, EventArgs e) { //ユーザーの変更を保存 FpSpread1.SaveChanges(); //非連結行をデータソースに追加します FpSpread1.Sheets[0].AddRowToDataSource(0, true); System.Diagnostics.Debug.WriteLine(string.Format("データソース行数：{0}", ((StockList)FpSpread1.DataSource).Count)); }
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load If IsPostBack Then Return FpSpread1.DataSource = New StockList() '非連結行を追加します FpSpread1.Sheets(0).AddUnboundRows(0, 1) System.Diagnostics.Debug.WriteLine(String.Format("データソース行数：{0}", CType(FpSpread1.DataSource, StockList).Count)) End Sub Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click 'ユーザーの変更を保存 FpSpread1.SaveChanges() '非連結行をデータソースに追加します FpSpread1.Sheets(0).AddRowToDataSource(0, True) System.Diagnostics.Debug.WriteLine(String.Format("データソース行数：{0}", DirectCast(FpSpread1.DataSource, StockList).Count)) End Sub
この例では、データソースとして以下のクラスを使用しています。
