How to get the value of a control from the caller form where the control is not bound to a datasource

Hi,

On the modified method of Field1, I want to first check the following:

  • The caller form is a specific form
  • The customer control on the current form is visible

    If that's the case, then I want to the value of the control from the caller form and assign it to the customer control in the current form  -- Note the control that I want to take it's value is not bound to a datasource

    how to do that?
    [FormControlEventHandler(formControlStr(CaseDetailCreate, Field1), FormControlEventType::Modified)]
    public static void CaseCategory_OnModified(FormControl sender, FormControlEventArgs e)
    {
        formRun callerFormNum = sender.formRun().args().caller();
        if(sender.formRun().args().callerName() == formstr(XXCustomerWorkspace) && XXcustomer.visible())
        {
            XXcustomer.Text(i want to get the value of the control that is not bound to a datasource from the caller form);
        }
    }

Also, I'm getting error on firstLine
Unable to cast object of type 'Dynamics.AX.Application.CaseDetailForm' to type 'Dynamics.AX.Application.FormRun'.'

I have the same question (0)

    Hi, In the first line, issue is that you have already mapped FormRun object with caller. Here caller is CaseDetailForm which is a class, not a Form. That's why system is throwing unable to cast object error.

    First check if caller is a form, check this article

    Hi Mohit,

    I can see that the caller In both cases is "CaseDetailForm" class

    But one is actually called from "CaseDetail"  form

    and one is called from XXCustomerWorkspace

    So maybe i need to get the caller of the caller in this case to know if it's coming from standard form CaseDetail or my new customized form XXCustomerWorkspace?  if yes how to do that?

    Also the other part of the question:

    i want to get the value of the control that is not bound to a datasource from the caller form

    Hi, You can try below code you find caller of the caller form

    FormRun callerFormRun = sender.formRun();
    FormRun origCallerFormRun = callerFormRun.args().caller();

    Regarding, accessing value of unbound form field, try accessing control from formRun.Design and accessing value of control.
