Populating a form Grid through a Temp table using a query

(0) ShareShare
ReportReport
Posted on by 305

Hello All,

I'm working in AX 2009. I have a form with a grid control, which I am trying to populate by using a Temporary table and an X++ query. The query is joining 4-tables, i.e., CustInvoiceTrans, CustInvoiceJour, InventDim, and CustTable.

The only range is on CustInvoiceTrans, InvoiceDate. I have set "Relations" to true for each, as CustInvoiceTrans.InvoiceId == CustInvoiceJour.InvoiceId and CustInvoiceTrans.InventDimId == InventDim.InventDimId and CustInvoiceJour.OrderAccount == CustTable.AccountNum.

The fields on the grid are from the temp table, which I dragged to the form's grid.

I have used a temp table before with success, but I am unable to get my grid to populate with data, although by placing a breakpoint in code and stepping thru the debugger I have been able to see data.

I have 3-methods in my project, the classDeclaration, the init, and a method named populateRecords, where I define the query class objects. The following is my code.

classDeclaration:
public class FormRun extends ObjectRun
{
    CustInvoiceTrans    custInvTransTmp;
    CustInvoiceJour      custInvJourTmp;
    InventDim                inventDimTmp;
    CustTable               custTableTmp;

    TmpSales_by_State_Table tmpDS;
}

populateRecords()
void populateRecords()
{
    Query                   query;
    QueryRun                queryRun;
    QueryBuildDataSource    qbds1,qbds2,qbds3,qbds4;
    QueryBuildRange         qr;

    ;

    delete_from tmpDS;

    query = new Query();
    qbds1 = query.addDataSource(tableNum(CustInvoiceTrans));
    qbds2 = qbds1.addDataSource(tableNum(CustInvoiceJour));
    qbds2.relations(true);
    qbds2.joinMode(JoinMode::InnerJoin);

    qbds3 = qbds1.addDataSource(tableNum(InventDim));
    qbds3.relations(true);
    qbds3.joinMode(JoinMode::InnerJoin);

    qbds4 = qbds2.addDataSource(tableNum(CustTable));
    qbds4.relations(true);
    qbds4.joinMode(JoinMode::InnerJoin);
    qr = qbds1.addRange(fieldNum(CustInvoiceTrans, InvoiceDate));

    queryRun = new QueryRun(query);


    if (queryRun.prompt())
    {
        while (queryRun.next())
        {
            custInvTransTmp = queryRun.get(tableNum(CustInvoiceTrans));
            custInvJourTmp = queryRun.get(tableNum(CustInvoiceJour));
            inventDimTmp = queryRun.get(tableNum(InventDim));
            custTableTmp = queryRun.get(tableNum(CustTable));

            tmpDS.InvoiceId = custInvJourTmp.InvoiceId;
            tmpDS.OrderAccount = custInvJourTmp.OrderAccount;
            tmpDS.InvoiceDate = custInvTransTmp.InvoiceDate;
            tmpDS.SalesId = custInvJourTmp.SalesId;
            tmpDS.ItemId = custInvTransTmp.ItemId;
            tmpDS.ExternalItemId = custInvTransTmp.ExternalItemId;
            tmpDS.LineAmount = custInvTransTmp.LineAmount;
            tmpDS.Qty = custInvTransTmp.Qty;
            tmpDS.PurchaseOrder = custInvJourTmp.PurchaseOrder;
            tmpDS.DueDate = custInvJourTmp.DueDate;
            tmpDS.DeliveryName = custInvJourTmp.DeliveryName;
            tmpDS.DlvCountryRegionId = custInvJourTmp.DlvCountryRegionId;
            tmpDS.DeliveryCity = custInvJourTmp.DeliveryCity;
            tmpDS.DlvState = custInvJourTmp.DlvState;
            tmpDS.DlvZipCode = custInvJourTmp.DlvZipCode;
            tmpDS.DeliveryAddress = custInvJourTmp.DeliveryAddress;
            tmpDS.InventLocationId = inventDimTmp.InventLocationId;
            tmpDS.InvoiceAccount = custInvJourTmp.InvoiceAccount;
            tmpDS.InvoicingName = custInvJourTmp.InvoicingName;
            tmpDS.InvCountryRegionId = custInvJourTmp.InvCountryRegionId;
            tmpDS.InvoiceCity = custInvJourTmp.InvoiceCity;
            tmpDS.InvState = custInvJourTmp.InvState;
            tmpDS.InvZipCode = custInvJourTmp.InvZipCode;
            tmpDS.InvoicingAddress = custInvJourTmp.InvoicingAddress;

            tmpDS.insert();

        }
    }
    TmpSales_by_State_Table.setTmpData(tmpDS);
}

init():
public void init()
{

    super();

    this.populateRecords();

}

Can anyone see what I am missing, or suggest another way of structuring my code? Thank you

    It turned out that the Grid's DataSource property was lost after removing and readding fields to the grid. After resupplying this property, the grid successfully displays data.
