x++ - 如何根据 AX 2012 AOT 报表中的另一个对话框字段过滤报表对话框中对话框字段上的查找值？

Question

如何在报告对话框中实现自定义查找。

例如，我的报告对话框中有两个字段 1) Custgroup 2) CustAccount

如果我在第一个字段中选择了一个特定的客户组，那么第二个字段查找应该只显示属于这个客户组的客户。

//class

    public class ReportRun extends ObjectRun
    {

        DialogField dialogcustGroup,dialogcustaccount ;
        CustTable  obj_CustTable ;
    }

   //dialog method
   public Object dialog(Object _dialog)
{
    DialogRunbase dialog = _dialog;
    DialogGroup     toFromGroup;
    Args _args;
    str accountnum,custGroup;
    ;
   // _args =  new Args();
   //  obj_dev_CustTable = _args.record(); 
    //accountnum = obj_dev_CustTable.AccountNum;

    dialogcustGroup = dialog.addFieldValue(extendedTypeStr(CustGroup),CustGroup,"");

    while select obj_CustTable
         where obj_CustTable.AccountNum == dialogcustGroup .value()
    {
         CID     =  obj_dev_CustTable.CID;
     dialogcustaccount =dialog.addFieldValue(ExtendedTypeStr(AccountNum),accountnum,"CID");
    }


    return dialog;
}  

任何帮助都会很棒！！！！

Answer 1

最好的方法是覆盖指定 DialogField 上的 lookup() 方法。请参见下面的示例 - 它工作得很好。

class CustomizedLookup extends RunBase
{
   DialogRunbase               dialog;
   DialogField                 dFieldCustGroup;
   DialogField                 dFieldCustAccount;
   CustGroupId                 fetchedCustGroup;
   CustAccount                 fetchedAccountNum;
}
protected Object dialog()
{
   dialog = super();

   FieldCustGroup = dialog.addField(extendedTypeStr(CustGroupId),"sysLabel1");
   dFieldCustGroup.allowEdit(true);

   dFieldCustAccount = dialog.addField(extendedTypeStr(CustAccount),"sysLabel1");
   dFieldCustAccount.allowEdit(false);

   return dialog;
}
public void dialogPostRun(DialogRunbase _dialog)
{
   super(_dialog);

// allow to call the event methods 
// of this class (e.g. Fld1_1_modified() method)
   _dialog.dialogForm().formRun().controlMethodOverload(true);
   _dialog.dialogForm().formRun().controlMethodOverloadObject(this);
}
private boolean Fld1_1_modified() // dFieldCustGroup
{
   FormStringControl   control;
   boolean             isFieldModified;

   control = dialog.formRun().controlCallingMethod();

   isFieldModified = control.modified();

   if(isFieldModified)
   {
       fetchedCustGroup   = dFieldCustGroup.value();
       dFieldCustAccount.allowEdit(true);
   }
   return isFieldModified;
}
private void Fld2_1_lookup() //dFieldCustAccount
{
   FormStringControl control = dialog.formRun().controlCallingMethod();
   SysTableLookup sysTableLookup =  SysTableLookup::newParameters(tablenum(CustTable),control);
   Query                   query = new Query();
   QueryBuildDataSource    queryBuildDataSource;
   QueryBuildRange         queryBuildRange;

   queryBuildDataSource = query.addDataSource(TableNum(CustTable));
   queryBuildRange = queryBuildDataSource.addRange(FieldNum(CustTable, CustGroup));
   queryBuildRange.value(fetchedCustGroup);  

   sysTableLookup.addLookupfield(fieldnum(CustTable, AccountNum));
   sysTableLookup.addLookupfield(fieldnum(CustTable, CustGroup));
   sysTableLookup.parmQuery(query);
   sysTableLookup.performFormLookup();
}
public boolean getFromDialog()
{
   boolean ret;

   ret = super();

   fetchedAccountNum = dFieldCustAccount.value();

   return ret;
}
static void main(Args _e)
{
   CustomizedLookup customizedLookup;

   customizedLookup = new CustomizedLookup();

   if (customizedLookup.prompt())
   {
       customizedLookup.run();
       // do some actions with your data 
       customizedLookup.theAction();         
   }
}
private void theAction()
{
   info(strFmt("Customer Group: %1",fetchedCustGroup));
   info(strFmt("Account Number: %1",fetchedAccountNum));
}

Answer 2

应该声明更多的方法，如 pack 、 unpack 和 main 方法

Answer 3

     public class CustAmountCalculation extends RunBase
{
    DialogField fieldAccount;
    CustAccount custAccount;

}

    public Object dialog()
{

    Dialog dialog;
    DialogGroup groupCustomer;
    dialog = super();
    fieldAccount = dialog.addField(extendedTypeStr(custAccount), "CustomerAccount");
    return dialog;
}

    public boolean getFromDialog()
{
    custAccount = fieldAccount.value();
    return super();
}

    public container pack()
{
    return conNull();
}


    public void run()
{
    CustTable custTable;
    CustTrans custTrans;
    ;

    select sum(AmountMST) from custTrans where custTrans.AccountNum == custAccount;
    info("You have enetered customer information");
    info(strfmt("Account: %1", custAccount));
    info(strFmt("Amount: %1", custTrans.AmountMST));
}

    public boolean unpack(container _packedClass)
{
    return true;
}

    public static void main(Args _args)
{
    CustAmountCalculation custAmountCalculation = new CustAmountCalculation();
    if (CustAmountCalculation.prompt())
    {
        CustAmountCalculation.run();
    }
}
