Excelファイルに送信される行をフィルタリングしようとしています。行データをExcelにエクスポートする方法を理解できましたが、バージョンドロップダウンを追加したため、フィルター処理されたデータをExcelシートに送信する必要があります。ドロップダウンから見たいバージョンを選択するとどうなりますか。

元。バージョンは12.1です。

ビューには、バージョン番号12.1が関連付けられているデータのみが返されます。フィルター処理された行をExcelファイルにダウンロードしたい場合。ダウンロードしてExcelファイルボタンを押すと、フィルターされた行ではなくすべての行が表示されることを除いて、Excelファイルでファイルが開きます。私がしなければならなかったのは、適切なviewbag変数とviewdata変数を呼び出しに追加することだけで、それは機能するだろうと思いました。私のコードを見て、私が間違っていることを理解するのを手伝ってくれませんか？以下のコードを投稿しました。より良い診断のためにさらに情報が必要な場合はお知らせください。頻繁にチェックします。ご協力いただきありがとうございます！

わかりました。1時間前にこの質問を投稿したばかりですが、それを理解しました。同じ問題が発生している場合は、他の人がこの回答を参考にしてくれることを願っています。私のExcel呼び出しの問題は、多くの変数が必要だったということでした。

ダウンロードボタンのアクションリンクは以前は次のようになりました

<div class="righty">
@Html.ActionLink("Download in Excel Format", "PaExcelOutput", "Pa", new { VERS = ViewBag.SelectedVersion, currentFilter = ViewBag.currentFilter, sortOrder = ViewBag.CurrentSort, @class = "button1" })

</div>

これに変更しました

<div class="righty">

@Html.ActionLink("Download in Excel Format", "PaExcelOutput", new { VERS = ViewBag.SelectedVersion, currentFilter = ViewBag.currentFilter, sortOrder = ViewBag.CurrentSort }, new { @class = "button1" })

</div>

文からを削除"Pa"することで、ビューバッグが変数をExcel出力に渡さない原因となっていた余分な変数を削除しました。

actionlinkメソッドは次のようになります。

ActionLink(HtmlHelper, String, String, Object, Object)

今私は知っています...そして知ることは戦いの半分です！
