Question

This seems like it should be an easy answer, but I have searched everywhere for this and can’t seem to find what I am trying to do and i’m new to this so I might be missing something… Hopefully someone can help.

The purpose of this is to display a packing list of scanners (the dl) I am sending for repair and each repair issue has notes (the gv). I am able to get the dl to display correctly, but i can’t get the gv to display at all. Even when i hard code the “issuekey”. I get an Object not set to object error. Obviously i can’t keep it hard coded, so I try to pull the issuekey (via a DataKey)from the dl and pass it to the gv, I get “Index was out of range”. (when i step thru it comes up -1).

Here is the code i’m working with…. THANKS

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

Answer 1

I THINK I FOUND MY OWN ANSWER…. in the ASP of the DataList I added onItemDataBound=”dlShippingList_ItemDataBound” on vb i took out … Handles dlShippingList.ItemDataBound SOO FAR, it seems to be working perfectly!
