リストビュー「ListView1」があり、顧客のmssqlデータベースの顧客テーブルにリンクされています。OnItemDeleting= "ArchiveBeforeDelete"これで、通常のデータベースから削除する前に顧客をアーカイブ（アーカイブされた顧客のデータベースcustomerテーブルに移動）したいので、リストビューに追加しました。を使用してselectedindexを取得できましたe.ItemIndexが、インデックスを使用してデータ、より具体的にはCustomerID部分のみを抽出する方法がわかりません。プロパティとメソッドを調べましたが、機能するものが見つかりません。

編集： これがリストビューの.aspxページのコードです

そして、コードビハインドファイルに私が持っている

 protected void ArchiveBeforeDelete(object sender, ListViewDeleteEventArgs e)
    {
        int listIndex = (int)e.ItemIndex;
    }

それが私が持っているすべてです、それはインデックスを取得します。そして、@ itsme86が提案したようなことを試しましたが、まったく役に立ちませんでした...本当に必要なのはCustomerIDだけです。これにより、テーブルからその特定のIDを呼び出して、他のアーカイブされた顧客に挿入できます。テーブル...

イベント ハンドラーで取得できるように、"tr" タグに CustomerId を配置する必要があります。下記参照...

<asp:ListView ID="ListView1" runat="server" DataKeyNames="CustomerId" 
DataSourceID="SqlDataSource1" OnItemDeleting= "ArchiveBeforeDelete">
<AlternatingItemTemplate>
    <tr id="<%# Eval("CustomerId") %>"
        style="background-color: #FAFAD2;color: #284775;">
        <td>
            <asp:Button ID="ArchiveButton" runat="server" CommandName="Delete"
                Text="Archive" />
            <asp:Button ID="EditButton" runat="server" CommandName="Edit" Text="Edit" />
        </td>
        <td>
            <asp:Label ID="CustomerIdLabel" runat="server" 
                Text='<%# Eval("CustomerId") %>' />
        </td>
        <td>
            <asp:Label ID="CustomerStatusLabel" runat="server" 
                Text='<%# Eval("CustomerStatus") %>' />
        </td>
etc.

したがって、以前のコメントで提案したように、次のように .aspx ページで DeleteCommand を編集できます。

INSERT INTO ArchivedCustomers SELECT CustomerStatus, CustomerGroup, CustomerFirstName, CustomerLastName, CompanyName, CustomerAddress, CustomerCity, CustomerState, CustomerZipcode, CustomerEmail, CustomerEmail2, CustomerPhoneNumber, CustomerPhoneNumberExt, CustomerType, CustomerSubscriptionType, CustomerCost, CustomerPaymentMethod, CustomerSignUpDate, CustomerPickUpDay, CustomerPickUpDay2, CustomerNotes FROM Customers WHERE CustomerID = @original_CustomerID; DELETE FROM Customers WHERE CustomerId = @original_CustomerId"

ご覧のとおり、最初に ArchivedCustomers テーブルに挿入され、その後削除されます。ただし、エラーが発生しないようにするには、プロパティ ConflictDetection を CompareAllValues から OverwriteChanges に変更する必要がありました。誰かが説明したい場合は、お願いしますが、今のところ私が気にしているのは、それが機能するということだけです! :) @ Jake1164 に大いに感謝します。もしあなたが私にそのコードを投稿させなかったなら、私はそのコマンドを私がしたように素早く編集する能力を見なかったと思います.
