GridView 嵌套在 DataList 中

Question

这似乎应该是一个简单的答案，但是我到处搜索，似乎找不到我想要做的事情，而且我是新手，所以我可能会遗漏一些东西......希望有人可以帮忙。

这样做的目的是显示我要送去维修的扫描仪装箱清单（dl），每个维修问题都有注释（gv）。我能够让 dl 正确显示，但我根本无法让 gv 显示。即使我对“问题密钥”进行硬编码。我得到一个 Object not set to object 错误。显然我不能保持硬编码，所以我尝试从 dl 中提取问题密钥（通过 DataKey）并将其传递给 gv，我得到“索引超出范围”。 （当我通过它时出现-1）。

这是我正在使用的代码......谢谢

Sub LoadShippingList()
    dlShippingList.DataSource = WarehouseManager.GetScannerIssuesByScannerStatus(WarehouseManager.ScannerStatus.PendingShipForRepair)
    dlShippingList.DataBind()
End Sub

Protected Sub dlShippingList_ItemDataBound(sender As Object, e As System.Web.UI.WebControls.DataListItemEventArgs) Handles dlShippingList.ItemDataBound
    Dim dList As DataList = CType(sender, DataList)
    Dim intScannerIssueKey As Integer = dList.DataKeys(e.Item.ItemIndex)

    Dim gv As GridView
    gv = CType(e.Item.FindControl("gvShippingListIssueNotes"), GridView)
    gv.DataSource() = WarehouseManager.GetScannerIssueNotes(intScannerIssueKey)
    gv.DataBind()

End Sub

我想我找到了我自己的答案....在 DataList 的 ASP 中，我在 vb 上添加了 onItemDataBound="dlShippingList_ItemDataBound" 我取出...处理 dlShippingList.ItemDataBound SOO FAR，它似乎工作得很好！
