デザイナーでBindingSourceを複数作成してデータバインドでTextBoxとComboBoxに表示しているのですが、
Designer.csで自動生成される各BindingSourceのISupportInitialize.EndInit()の順番が悪くエラーになってしまいます。
型 'System.ArgumentException' のハンドルされていない例外が System.Windows.Forms.dll で発生しました
追加情報:DataMember プロパティ 'Inner1' は DataSource に見つかりません。
ISupportInitialize.EndInit()の順番はデザイナーウインドウでのドキュメントアウトライン
と同じなのでどこかでこの順番を指定できないでしょうか。
BindingSourceを再度指定し直せば一時的に直るのですが、何かの拍子に以下のソースのようになってしまいます。
メインのコードでは必ず発生するのですが、サンプルコードにするとほとんど発生しないため、原因がわかりません。
以下エラー時のソースです。
