Standard navigation button / How to avoid creating new record

Hi Naveen Boga,

Here is the begining of the graph declaration :

    public class EAPInvoiceEntry : PXGraph<EAPInvoiceEntry, EAPInvoice>
    {

EAPInvoice is quite a copy of APInvoice.

The graph main view :

        public SelectFrom<EAPInvoice>
            .LeftJoin<Vendor>.On<Vendor.bAccountID.IsEqual<EAPRegister.vendorID>>
            .View DocumentView;

I have joined the aspx file to the post. Do you need anything else ?

Thx

I see. It’s normal : the .zip file just contains the .aspx file and not my customization, that is too heavy to be easily posted.

Hello andriikravetskyi35,

Thank you for your suggestion, which seems to be a good way forward. Unfortunately, it doesn’t work in my case.I’m continuing my search...

Can you figure out somehow if you are on the last record or not? If so, then you can disable the Next action in RowSelected.

 protected virtual void _(Events.RowSelected<EAPInvoice> e)
 {
    if (e.Row == null) return;

    var isLastRecord = /** e.Row.ID == MaxID from another view??? **/
    Next.SetEnabled(!isLastRecord);
  }
}

Good morning everyone,

@zfebert56  Here is one more idea how you might override Next button, example on Sales Order screen, but you could do the same on your screen:

 public class SOOrderEntryExt : PXGraphExtension<SOOrderEntry>
 {

  public static bool IsActive() => true;

  public PXNextMyLogic<SOOrder> Next;

  public class PXNextMyLogic<TNode> : PXPrevNextBase<TNode> where TNode : class, IBqlTable, new()
   {
    protected override int DefaultStartRow => 0;

    public PXNextMyLogic(PXGraph graph, string name) : base(graph, name) { }

    public PXNextMyLogic(PXGraph graph, Delegate handler) : base(graph, handler) { }

    [PXUIField(DisplayName = "Next", MapEnableRights = PXCacheRights.Select)]
    [PXNextButton]
    protected override IEnumerable Handler(PXAdapter adapter)
    {

     // do some selects, check data and return from method or run baseMethod

                adapter.StartRow += adapter.MaximumRows;
                return base.Handler(adapter);
    }
  }
}

Hope it help you to solve your issue.

PS: just for information, don’t select any information in RowSelected event, it will slow performance of screen. If you need select data from DB, do it in RowSelecting event, using PXConnectionScope()

Sorry for my late reply but I had a lot of meetings yesterday afternoon. Thanks a lot for all your smart suggestions ! I've tested a merge of them and it works : the "Next" action button doesn't lead to a new record when activated on the last record.My code below. Once again, thank you for your invaluable help, without which I would still be searching.

        public new PXNextRestricted<EAPInvoice> Next;

        public class PXNextRestricted<TNode> : PXPrevNextBase<TNode> where TNode : class, IBqlTable, new()
        {
            protected override int DefaultStartRow => 0;

            public PXNextRestricted(PXGraph graph, string name) : base(graph, name) { }

            public PXNextRestricted(PXGraph graph, Delegate handler) : base(graph, handler) { }

            [PXUIField(DisplayName = "Next!", MapEnableRights = PXCacheRights.Select)]
            [PXNextButton]
            protected override IEnumerable Handler(PXAdapter adapter)
            {
                EAPInvoiceEntry eapInvoiceEntryGraph = base.Graph as EAPInvoiceEntry;
                EAPInvoice currentEapInvoice = eapInvoiceEntryGraph.DocumentView.Current;

                IEnumerable defaultResult = adapter.Get();

                adapter.StartRow += adapter.MaximumRows;
                IEnumerable result = base.Handler(adapter);

                bool isLastRecord = currentEapInvoice != null && currentEapInvoice.RefNbr != null && currentEapInvoice.RefNbr.Equals(eapInvoiceEntryGraph.lastRecordID);

                if (isLastRecord)
                {
                    SetEnabled(false);
                    result = defaultResult;
                }
                else
                {
                    SetEnabled(true);
                }
                
                return result;
            }
        }
