Control editing form fields

If you want to control which of the fields on a form are editable, you can use the property allowEdit of the datasource fields. If you have large tables containing a lot of fields, this could be a time-consuming process.

So, if you have a form, where the user should only be able to edit one field - in particular case a field from table salesLine -, you could use the following code-example which should be included in the init-method of the datasource. The snippet disallows editing for all fields exept for one field. 

public void init()
{
    sqlDictionary   sqlDictionary;
    ;
   
    super();

    while select sqlDictionary
    where sqlDictionary.tabId   == tableNum(salesLine)
       && sqlDictionary.fieldId != 0
    {
        if(sqlDictionary.name != "dataareaid" &&
           sqlDictionary.name != "recversion" &&
           sqlDictionary.name != "recId"
        )
        {
            salesline_ds.object(sqlDictionary.fieldId).allowEdit(false);
        }
    }
    salesline_ds.object(fieldNum(salesLine, blocked)).allowEdit(true);
}

Working with the calling object of a form (Caller)

The following method contains some snippets that can be used to call various functions/methods of the calling object (form).

If you change element.args() to e.g. _args and pass the arguments to the method, you can use the code within a class as well.

void workWithCallingRecord()
{
    common          common;
    object          object;
    formDataSource  formDataSource;
    formRun         formRun;
    inventDim       inventDim;
    salesTable      salesTable;
    int             i;
    ;
    // Call method from calling record
    if( element.args() &&
        element.args().record() )
    {
        common = element.args().record();
        if(common.isFormDataSource())
        {
            info(tableId2Name(common.TableId));
            if(formDataSourceHasMethod(common.dataSource(), identifierStr("someMethod")))
            {
                object = common.dataSource();
                object.someMethod();
            }
        }
    }
 

    // Call method from calling form
    if(element.args() && element.args().caller() && element.args().caller().handle() == className2Id('formRun'))
    {
        formRun = element.args().caller();
        if(sysFormRun::hasMethod(formRun, identifierStr("someFormMethod")))
        {
            object = formRun;
            object.someFormMethod();
        }
    }

    // Get value from calling record
    if( element.args() &&
        element.args().record() )
    {
        common = element.args().record();
        if(common.TableId == tableNum(salesTable))
        {
            info(common.(fieldNum(salesTable, salesId)));
        }
    }

    // Get value from calling datasource (form with multiple datasources)
    if(element.args() && element.args().caller() && element.args().caller().handle() == className2Id('formRun'))
    {
        formRun = element.args().caller();
        for (i = 0; i <= formRun.dataSourceCount(); i++)
        {
            formDataSource = formRun.datasource(i);
            if (formDataSource && formDataSource.table() == tablenum(inventDim))    // Search for specific table
            {
                inventDim = formDataSource.cursor();
                break;
            }
        }
        if(inventDim)
        {
            info(inventDim.InventLocationId);
        }
    }

    // Change data in calling datasource
    if(element.args() && element.args().caller() && element.args().caller().handle() == className2Id('formRun'))
    {
        formRun = element.args().caller();
        for (i = 0; i <= formRun.dataSourceCount(); i++)
        {
            formDataSource = formRun.datasource(i);
            if (formDataSource && formDataSource.table() == tablenum(salesTable))    // Search for specific table
            {
                salesTable = formDataSource.cursor();
                break;
            }
        }
        if(salesTable)
        {
            // Update data
            salesTable.PurchOrderFormNum = "Some value";
            salesTable.update();
        }
    }

    // Refresh calling datasource
    if( element.args() &&
        element.args().record() )
    {
        common = element.args().record();
        if(common.isFormDataSource())
        {
            formDataSource = common.dataSource();
            formDataSource.research(true);
        }
    }
}

 
 

Dynamics AX: Illegal property value

If you try to change the AllowDuplicates-Property of a table index from No to Yes, the following error message may occur:

Illegal property value

In this case, presumably, the affected index is registered as PrimaryIndex or ClusteredIndex of the table.


 
 

Dynamics AX: Print SalesInvoice through code

Using the following code you can easily print sales invoice through code. With slight modifications to the code, this is also true for all other sales- and purchase-sided documents.

Short example in AX 2009

static void PrintSalesInvoice(Args _args)
{
   custInvoiceJour     custInvoiceJour;
   SalesFormLetter     salesFormLetter = SalesFormLetter::construct(DocumentStatus::Invoice, false);
   PrintJobSettings    printJobSettings = new PrintJobSettings();
   Args                args = new Args();
   boolean             prompt = true;
   boolean             printIt = true;
   ;

   if (prompt)
   {
       // Dialog
       printIt = printJobSettings.printerSettings('SysPrintForm');
   }
   else
   {
       // Printjobsettings
       printJobSettings.setTarget(PrintMedium::File);
       printJobSettings.format(PrintFormat::PDF);
       printJobSettings.fileName(@'c:	empmyfile.pdf');
   }

   if (!printIt)
   {
       return; 
   }

   salesFormLetter.updatePrinterSettingsFormLetter(printJobSettings.packPrintJobSettings());

   select firstOnly custInvoiceJour
       where custInvoiceJour.salesid == '100001';

   args.record(custInvoiceJour);
   args.caller(salesFormLetter);

   new MenuFunction(menuitemoutputstr(SalesInvoice), MenuItemType::Output).run(args);
}

Short example in AX 4.0

static void PrintSalesInvoice(Args _args)
{
   custInvoiceJour     custInvoiceJour;
   SalesFormLetter     salesFormLetter = SalesFormLetter::construct(DocumentStatus::Invoice, false);
   PrintJobSettings    printJobSettings = new PrintJobSettings();
   Args                args = new Args();
   boolean             prompt = true;
   boolean             printIt = true;
   salesPrintSetup     salesPrintSetup;
   ;

   if (prompt)
   {
       // Dialog
       printJobSettings = new PrintJobSettings(salesPrintSetup.PrintJobSettings);
       printIt = printJobSettings.printerSettings('SysPrintForm');
       salesPrintSetup.PrintJobSettings = printJobSettings.packPrintJobSettings();
   }
   else
   {
       // Printjobsettings
       printJobSettings.setTarget(PrintMedium::File);
       printJobSettings.format(PrintFormat::PDF);
       printJobSettings.fileName(@'c:	empmyfile.pdf');
   }

   if (!printIt)
   {
       return; 
   }

   salesFormLetter.updatePrinterSettingsFormLetter(printJobSettings.packPrintJobSettings());

   select firstOnly custInvoiceJour
       where custInvoiceJour.salesid == '100001';

   args.record(custInvoiceJour);
   args.caller(salesFormLetter);

   new MenuFunction(menuitemoutputstr(SalesInvoice), MenuItemType::Output).run(args);
}
