How to create a dynamic fields in form?

Posted on by junior AX 1,552

Hi,

I want to create a control in form by code (not actual control) -- how can i do that?

It needs to appear based on conditions.

So let's say if a standard control is filled, then the control created by code needs to appear..and if it's a filled another control that i will create by code needs to appear 

There is no limit to how many controls needed that's why i want it dynamic and not actual controls as they need to appear based on conditions 

I have the same question (0)

    Have a look at the standard tutorial_Form_AddControl form, here is the code below. It demonstrates the basics of how to do add form controls at runtime. Also with events like validate.

    [Form]
public class tutorial_Form_AddControl extends FormRun
{
    int  i;

    public void run()
    {
        // Create a dummy control to use so all dynamically added controls can register to its override
        FormBuildDesign             formBuildDesign = form.design();
        FormBuildGroupControl       formBuildGroupControl;
        FormStringControl c;

        
        ;
        c = addGroup.addControl(FormControlType::String,'runTimeControl');
        c.label("Dummy control");
        c.registerOverrideMethod(methodStr(FormStringControl, validate), 'runTimeControl_validate');
        c.visible(false);

        formBuildGroupControl = formBuildDesign.control( addGroup.id() );
        super();
    }

    public boolean runTimeControl_validate(FormStringControl stringControl)
    {
        boolean ret;
        ;

        ret = stringControl.validate(); // Same as calling super in the control::validate

        warning(funcname()   ' Control:'   stringControl.Label()   ' Value:'   stringControl.valueStr());
        return ret;

    }

    [Control("Button")]
    class Button
    {
        void clicked()
        {
            FormBuildDesign             formBuildDesign = form.design();
            FormBuildGroupControl       formBuildGroupControl;
            FormStringControl c;
            ;

            i  ;
            // Add the control - increment control name by 1
            c = addGroup.addControl(FormControlType::String, 'runTimeControl'   int2str(i));
            c.width(300);

            // register the controls validate override 
            c.registerOverrideMethod(methodStr(FormStringControl, validate), 'runTimeControl_validate');
                        
            // set the controls label name
            c.label('New Control - runTimeControl'   int2str(i));

            formBuildGroupControl = formBuildDesign.control( addGroup.id() );
        }

    }

}
