Form Control Event Handler Methods in Dynamics 365 for Operations (AX7)

Hi,

For example, In Dynamics 365 for Operations (AX7) you can react to the OnClicked event by copying the event handler method for the event and pasting the method into a class. 

Below is an example of an event handler method that reacts to the OnClicked event of a button on a form.

Create new Class and paste below code in it for SalesEditLines EventHandlers

 /// <summary>
    ///
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    [FormControlEventHandler(formControlStr(SalesEditLines, OK), FormControlEventType::Clicked)]
    public static void OK_OnClicked(FormControl sender, FormControlEventArgs e)
    {
        Args args = new Args();
        FormCommandButtonControl  callerButton = sender as FormCommandButtonControl;  //Retrieves the button that we're reacting to
        FormRun form = callerButton.formRun(); //Gets the running SalesEditLines form

        //Get the salesId that was selected in the SalesEditLines form
        FormDataSource salesParmTable_ds = form.dataSource(formDataSourceStr(SalesEditLines, SalesParmTable)) as FormDataSource;
        SalesParmTable salesParmTable = salesParmTable_ds.cursor();


        SalesTable salesTable=salesParmTable.salesTable();

        if(salesTable.SalesStatus==SalesStatus::Invoiced)
        {
     
//Any Action

        }
    }

    [FormControlEventHandler(formControlStr(EcoResProductDetailsExtended, Other_CatchWeight), FormControlEventType::Modified)]
    public static void Other_CatchWeight_OnModified(FormControl sender, FormControlEventArgs e)
    {
        FormCheckBoxControl  callerButton = sender as FormCheckBoxControl ;  //Retrieves the button that we're reacting to
        FormRun element = callerButton.formRun();
        FormControl catchweightMultipleToSubProject = element.design(0).controlName("Other_CatchweightMultiple");
        if(callerButton.checked())
        {
            catchweightMultipleToSubProject.allowEdit(true);
        }
        else

            catchweightMultipleToSubProject.allowEdit(false);
        }
    }


On Look Up Event for String Control in the form

 [FormControlEventHandler(formControlStr(VendBankAccounts, PartyPaymLocationName), FormControlEventType::Lookup)]
    public static void PartyPaymLocationName_OnLookup(FormControl sender, FormControlEventArgs e)
    {
        FormControl   callerStr = sender as FormControl;  //Retrieves the string that we're reacting to
        FormRun form = callerStr.formRun(); //Gets the running VendBankAccounts form

        FormDataSource vendBankAccount_ds = form.dataSource(formDataSourceStr(VendBankAccounts, VendBankAccount)) as FormDataSource;
        VendBankAccount vendBankAccount = vendBankAccount_ds.cursor();

        vendBankAccount.vendPartyPaymLookup(callerStr );
 

    }

 public static void InventoryDimensionsGrid_LicensePlateId_OnEnter(FormControl sender, FormControlEventArgs e)
    {
            FormControl   callerStr = sender as FormControl;  //Retrieves the string that we're reacting to
            FormRun form = callerStr.formRun(); //Gets the running  form

            FormStringControl InventoryDimensionsGrid_LicensePlateId = form.design(0).controlName("InventoryDimensionsGrid_LicensePlateId");

            if(InventoryDimensionsGrid_LicensePlateId.text())
            {
                WHSLicensePlate::createLicensePlate(InventoryDimensionsGrid_LicensePlateId.text());
            }
    }

Assign or SET value to Form string control 

 [FormControlEventHandler(formControlStr(InventJournalTransferReceive, InventDimIssue_InventBatchId), FormControlEventType::Modified)]

    {

        FormControl   callerStr = sender as FormControl;  //Retrieves the string that we're reacting to

        FormRun form = callerStr.formRun(); 

     

//   FormDataSource dsInventJournalTrans = sender.formRun().dataSource("InventJournalTrans");

     

        FormStringControl InventJournalTrans_PurchId = form.design(0).controlName("InventJournalTrans_PurchId");

     

        

     

               InventJournalTrans_PurchId.enabled(true);

                //True parameter append the text but false removes existing text and paste new text

                InventJournalTrans_PurchId.pasteText("SET TEXT HERE",FALSE);

                InventJournalTrans_PurchId.enabled(false);
