从listview中提取数据

我有一个listview“ListView1”,它链接到我的客户mssql数据库上的客户表。现在,我已将OnItemDeleting= "ArchiveBeforeDelete"添加到Listview中,因为我希望客户在从普通数据库中删除之前归档(移动到我的归档客户的数据库客户表)。我已经能够使用e.ItemIndex检索selectedindex,但现在我无法弄清楚如何使用索引提取数据,更具体地说是提取CustomerID部分。我查看了属性和方法,找不到有效的方法。

修改 以下是listview

的.aspx页面中的代码

然后在我有的代码隐藏文件中

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

这就是我所拥有的,它获得了索引。然后我尝试了@ itsme86建议的东西,但一切都无济于事......我真正想要的是CustomerID,这样我就可以从表中调用该特定的ID,然后插入其他存档的客户表...

您应该将CustomerId放在“tr”标记上,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那样,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"

正如您所看到的,首先它被插入到ArchivedCustomers表中,然后它被删除了,我已经完成了它。有一点需要注意,我必须将属性ConflictDetection从CompareAllValues更改为OverwriteChanges以便停止收到错误。如果有人关心解释,请做,但是现在我所关心的只是它的工作! :) 非常感谢@ Jake1164,如果您没有让我发布该代码,我认为我不会像我那样快速地编辑该命令。
