Call a Form method from FormDataFieldEventHandler

(0) ShareShare

Posted on by Community Member Microsoft Employee

Hi,

I am customizing InventTransferOrders Form. I want to initialize few fields based on newly created custom field.

I want to call form method 'updateItemId()' to run the logic for initializing ItemId field. I created the event handler of 'onModified()' method. I have initialized the FormRun object and trying to call form methods from it but I cannot see the method. 

Can you please help me how I can call form methods and variables in event handler?

Thanks in advance!

Regards,

Sohagani Shah

    RE: Call a Form method from FormDataFieldEventHandler

    Please note that this is a Type conversion approach, there you are declaring FormRun and calling a method which actually does not exist on a FormRun object, to overcome this and write a nice code you can change declaration of your form, for example:

    public class CustomForm extends FormRun implements CustomFormClassImplement

    And then create an instance of a class CustomFormClassImplementand call a method from this class.

    CustomFormClassImplement customFormClassImplement = purchLine_ds.formRun();

    customFormClassImplement.UpdateItemId() ,

    Although it is a bit harder with a standard forms as you cannot change form declaration. But still possible by extending some class(if exists)

    Hi Sohagani,

    Maybe you have found solution . But I hope this can help others.

    [FormDataFieldEventHandler(formDataFieldStr(PurchTable, PurchLine, itemBarCode), FormDataFieldEventType::Modified)]

public static void itemBarCode_OnModified(FormDataObject sender, FormDataFieldEventArgs e)

{

     FormDataSource purchLine_ds = sender.datasource();

    PurchLine purchLine = purchLine_ds.cursor();
    
    FormRun formRun =   purchLine_ds.formRun();
    if(formHasMethod(formRun,formMethodStr(PurchTable,updateItemId))
    
    {
    
        formRun.updateItemId();
    
    }

}

    Hi Sohagani,

    Can you explain in detail what you are doing? Where and how did you create new fields? What is the relation between these fields and calling the method you have mentioned? Do you have other additional logic or requirements?

    Usually we don't get IntelliSense for any additional methods other than base(FormRun) methods in the eventhandlers  using FormRun object. You can simply hard code the method and it will be called in the run time.

    You should be able to get formRun as below and then called method using formrun object

    FormRun formRun = sender.formRun() as FormRun;  

    formRun.myCustomMethod()

    // Get the selected datasource record    TableName tableBuffer = sender.cursor();  

    // Get datasource variable     FormDataSource DSVariable = sender.formRun().dataSource(“TableName”); }

    even if you don't see method in IntelliSense try to build it and see if you are getting any error.
