Assigning a value to a control and executing edit method via code in a form

(0) ShareShare
ReportReport
Posted on by Community Member

I have 2 fields on a form, both are reals. Field1 is a value in a grid, EditField2 is an edit method in the footer of the form. The edit method has some standard AX logic that I need to execute, using the value in Field1.

The functionality I'm looking for is: When I enter a value in Field1, it populates the value in EditField2, and executes the logic in the corresponding method. Basically, I want it to act as if the same value as was entered into Field1 was entered into EditField2 and then the user hit tab or enter.

In the Modified event handler for Field1, I've done this:

[FormControlEventHandler(formControlStr(SalesReleaseOrderPicking, SalesLine_InventDeliverNow), FormControlEventType::Modified)]

    public static void SalesLine_Field1_OnModified(FormControl sender, FormControlEventArgs e)

    {

        real lclQty;

        FormRun element                                 = sender.formRun();

 FormRealControl Field1        = element.design(0).controlName("Field1");

        FormRealControl EditField2 = element.design(0).controlName("Control2");

        FormRun formRun = sender.formRun();

        FormDataSource fds = formRun.dataSource(formDataSourceStrSalesLine

                              SalesLine)) as FormDataSource;

        SalesLine lclSalesLine = sender.formRun().dataSource(3).cursor();

        lclQty = lclSalesLine.QtyField;

        if (lclQty)

        {

            EditField2.realValue(lclQty);

         **   

            

        }

    }

My question is: Where I've put "**" in the code sample, what command would simulate an Enter in EditField2, so that the edit method will execute without user intervention?

Thank you in advance!

    RE: Assigning a value to a control and executing edit method via code in a form

    Hi, 

    Fetch in the sense I mean, how to call. 

    Ex: formcontrol myControl = sender;

    Object formrun = myControl.FormRun() ;

    Str myEditvalue = formRun.editPurchAgreementId();// example

    So here can I get the edit method value in my string variable.?

    What do you mean by "fetch"?

    You can call form methods if you have the FormRun object. But you don't want to call the method, you want to run your own checks when the method is being called.

    Hi all,

    That's true. The FormDataSource class doesn't have that method, and that's why the compiler gives you an error. But with Object class there is no such check. Instead your code will fail in runtime if you call something that doesn't exist.

    To prevent such runtime errors, you can use formHasMethod method to check if the called form has a method that you intend to use. Maybe there is formDataSourceHasMethod available too. I don't have a system at hand right now so I can't check.

    I found it. When I changed the FormDataSourcce to Object, it works. Not sure why...

    Old:

    FormDataSource fds = formRun.dataSource(formDataSourceStr(SalesLine,

                                SalesLine)) as FormDataSource;

    fds.reserveNow(true, lclSalesLine, lclQty);

    New:

    Object fds = formRun.dataSource(formDataSourceStr(SalesLine,

                                SalesLine)) as FormDataSource;

    fds.reserveNow(true, lclSalesLine, lclQty);

    What if you try this

    1) Add a new method to the form root level with form extension. 

    2) Make this method call the edit method of the data source. 

    3) Call your form level method from your event handler (formRun.myNewMethod())

    fds also does not find it. The name of the edit method is 'reserveNow', in the SalesReleaseOrderPicking form. It is a method on the SalesLine data source in that form. This is the method definition on the standard form: public edit InventQty reserveNow(boolean _set, SalesLine  _salesLine, InventQty  _reserveNow)

    I tried:

    FormDataSource fds = formRun.dataSource(formDataSourceStr(SalesLine,

                                 SalesLine)) as FormDataSource;

    fds.reserveNow(true, lclSalesLine, lclQty);

    It still errors, saying that the data method can not be found.

    Again, thank you!

    If you have a method called yourMethod in your form data source, and if you have your form data source in variable fds, you can simply call your method like this:

    fds.yourMethod();
