GridView嵌套在DataList中

这似乎应该是一个简单的答案,但我已经到处寻找这个,似乎无法找到我想做的事情,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发送修理的扫描仪(dl)的装箱单,每个修理问题都有注释(gv)。我能够正确显示dl,但我根本无法显示gv。即使我硬编码“问题密钥”。我得到一个Object没有设置为对象错误。显然我不能保持硬编码,所以我尝试从dl拉出问题密钥(通过DataKey)并将其传递给gv,我得到“索引超出范围”。 (当我一步到位时,它会出现-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

我认为我发现了自己的答案....在DataList的ASP中我在vb上添加了onItemDataBound =“dlShippingList_ItemDataBound”我拿出了...处理dlShippingList.ItemDataBound SOO FAR,它似乎工作得很好! / p>
