我有一个列表视图“ListView1”，它链接到我的客户 mssql 数据库上的客户表。现在，我已添加OnItemDeleting= "ArchiveBeforeDelete"到 Listview 中，因为我希望在将客户从普通数据库中删除之前对其进行存档（移动到我存档客户的数据库客户表中）。我已经能够使用索引来检索 selectedindex，e.ItemIndex但现在我无法弄清楚如何使用索引提取数据，更具体地说，只是 CustomerID 部分。我查看了属性和方法，但找不到有效的方法。

编辑： 这是列表视图的 .aspx 页面中的代码

然后在我的代码隐藏文件中

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

这就是我所拥有的，它得到了索引。然后我尝试了@itsme86 建议的方法，但都无济于事......我真正想要的是CustomerID，这样我就可以从表中调用该特定ID，然后插入其他存档客户桌子...

您应该将 CustomerId 放在“tr”标签上，这样您就可以在事件处理程序中将其取回。见下文...

<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.

因此，正如我在之前的评论中所建议的，可以在 .aspx 页面中编辑 DeleteCommand，如下所示：

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"

如您所见，首先将其插入到 ArchivedCustomers 表中，然后在我完成后将其删除。不过需要注意的一件事是，我必须将属性 ConflictDetection 从 CompareAllValues 更改为 OverwriteChanges 以停止出现错误。如果有人愿意解释，请做，但现在我只关心它的工作原理！:) 非常感谢@Jake1164，如果您没有让我发布该代码，我认为我不会像我一样快速地看到编辑该命令的能力。
