ページに複数のModalPopupが含まれ、それぞれにValidationSummaryコントロールが含まれている場合に問題が発生します。
必要な機能は次のとおりです。
- ユーザーがボタンをクリックすると、クリックされたボタンに基づいた動的コンテンツを含むモーダルポップアップが表示されます。(この機能は機能しています。ボタンはUpdatePanelsでラップされ、部分的なページのポストバックはModalPopupで.Show()を呼び出します)
- ModalPopupの[保存]ボタンを押すと、クライアント側の検証が行われ、その後、ページ全体のポストバックが行われるため、ModalPopup全体が表示されなくなります。(ModalPopupは別の方法で消える可能性があります-ModalPopupは、保存操作が成功した後に消える必要があります)
- 保存操作中に分離コードでエラーが発生した場合、メッセージがValidationSummary(ModalPopup内に含まれる)に追加され、ModalPopupが再度表示されます。
ValidationSummaryがPopupPanelに追加されると、2番目のPopupPanel内の[保存]ボタンが原因でページ全体がポストバックされた後、ModalPopupが正しく表示されなくなります。(最初のパネルは引き続き正しく機能します)両方のPopupPanelが表示され、どちらも「Popped-Up」ではなく、インラインで表示されます。
これを解決する方法について何かアイデアはありますか?
編集:各ポップアップの機能は異なります-そのため、2つの異なるModalPopupが必要です。
編集2:私が受け取っていたJavascriptエラー:
function(){Array.remove(Page_ValidationSummaries、document.getElementById(VALIDATION_SUMMARY_ID)); }(function(){var fn = function(){AjaxControlToolkit.ModalPopupBehavior.invokeViaServer( "MODAL_POPUP_ID"、true); Sys.Application.remove_load(fn);}; Sys.Application.add_load(fn);})はありません機能
ない ";" 注入されたjavascriptで。以下の回答を参照してください
