RecordInserList class for optimized insert operation

Hi Folks,

RecordInsertList class is the really useful and fastest way to insert records in AX table(s). This method is useful you don't want to run any validation while insertion for an example; insert in a temp table or SSRS reports. 

Below is the simplest example of set based RecordInserList class,
void copyVendor()
    VendTable    sourceVend;
    MyTmpTable   targetVend;

    //RecordInserList calss decarion
    RecordInsertList VendList;

  //Object initialization
    VendList = new RecordInsertList(tableNum(Vendtable));

    while select sourceVend
    where sourceVend.vendgroupId == ‘Local’
        targetVend.vendorAccount = sourceVend.vendorAccount;
    VendList.insertDatabase(); //mandatory call

Another example from MSDN

public void tutorialRecordInsertList()
        MyTable myTable;
        RecordInsertList insertList = new RecordInsertList(
        int i;
        for ( i = 1; i <=  100; i++ )
            myTable.value = i;

RecordInserList class will capture all record in temp and hit The DataBase only once when we call insertDatabase(). add() insert certain blocks followed by insertDatabase to complete the insert operation. 
This is how we can reduce the SQL call and optimize the performance as well.

Form Event handler methods in Dynamics 365 FO

Hi Guys,

Let’s discuss today the different event handlers in Dynamics 365 FO. Now we don't have the leverage 😉to overwrite existing code anymore so all you have is event handlers to manipulate standard functionality. However, event handlers were available in the earlier version as an optional and best practice but now it’s the only option. I will be sharing different event handler so we can cover most of the methods with different parameters.

1. Form dataSource event handler: Here I will be using the vendTable form to get table buffer and perform additional business logic or validation.

Vendtable = Form name
vendTable = form data source name
[FormDataSourceEventHandler(formDataSourceStr(Vendtable, vendTable), FormDataSourceEventType::Written)]
public static void vendTable_OnWritten(FormDataSource sender, FormDataSourceEventArgs e)
    FormRun                 form           = sender.formRun();
    FormDataSource          vendTable_ds =       form.dataSource(formDataSourceStr(Vendtable,Vendtable)) as FormDataSource;
   Vendtable     Vendtable= vendTable_ds.cursor();
<Now to got table buffer, perform business logic/validation>
lets see one more example below;

2. Form DataSource while closing the form (same will apply for OnInitialized,
[FormEventHandler(formStr(EcoResAttributeValue), FormEventType::Closing)]
public static void EcoResAttributeValue_OnClosing(xFormRun sender, FormEventArgs e)
     FormDataSource ecoResProduct_ds   =          sender.dataSource(formDataSourceStr(EcoResAttributeValue, EcoResProductAttributeValue));
      EcoResProductAttributeValue      ecoResAttributeValue = ecoResProduct_ds.cursor();

3.  Post-event hander of Form init or any other standard method method
[[PostHandlerFor(formStr(Ledger), formMethodStr(Ledger, init))]
    public static void Ledger_Post_init(XppPrePostArgs _args)
        FormRun form = _args.getThis();
        FormDesign design =;
        FormControl revaluationAccount = design.controlName(formControlStr(Ledger, revaluationAccount));
        FormControl currencyRevaluation = design.controlName(formControlStr(Ledger, currencyRevaluation));

<your code>

4. Form control event hander:
[FormControlEventHandler(formControlStr(LogisticsPostalAddress, Roles), FormControlEventType::Modified)]
    public static void Roles_OnModified(FormControl sender, FormControlEventArgs e)
        FormRun element = sender.formRun();
        FormControl purposeCtrl   =, Roles));
        FormDataSource logisticsLocation_DS = element.dataSource(formDataSourceStr(LogisticsPostalAddress, LogisticsLocation));
       <business logic>
