Does anyone know how to refresh a grid on another form through a button? I mean when I add something, I want to see it reflected immediately on the other form.

    Is the form your are updating get opened from the other form? In that case you can capture the caller as Formrun caller = element.args().caller(); in init method. Then use caller.dataSource().research(true); on save button or modified method of fields to refresh caller. – Pradeep Muttikulangara Vasu Jan 20 '17 at 19:03
  • Hello again, thanks you for your time :D, form A have the grid, and when I press a button appers the form B whats its where I add data to the grid on the form A, so like I understand I put all on the form B `Formrun caller;` on the ClassDeclaration, `caller = element.args().caller();` on the Init method and `caller.dataSource().research(true);` on the add button, but sends me an error:: FormRun Object Not initialized... – Paul Noris Jan 20 '17 at 20:19
  • When you open form B from form A add the following line of code to initialize caller `args.caller(this)`. Also you should always check that object is not null `if (element.args() != null && element.args().caller() != null`. – Aliaksandr Maksimau Jan 20 '17 at 20:51
  • Is not working :s this is the code of the field with leave method `ret = super(); args = new args(); args.caller(this); args.parm( Field_OnFormA ); args.name( formstr( Form_B ) ); formRun = classFactory.formRunClass( Args ); formRun.init(); formrun.run(); formrun.wait(); return ret;` – Paul Noris Jan 20 '17 at 23:09
  • This is the code on the ClassDeclaration form_B `public class FormRun extends ObjectRun { Formrun caller; }` – Paul Noris Jan 20 '17 at 23:10
  • here is the code on the init : `super(); caller = element.args().caller(); if(!element.args().caller()) { throw error("Cant Run Directly"); } ` – Paul Noris Jan 20 '17 at 23:11
  • and here the button `super(); caller.dataSource().research(true);` – Paul Noris Jan 20 '17 at 23:11

    If your code is placed on control then use `args.caller(element)` instead of `args.caller(this)` http://stackoverflow.com/questions/4260403/this-vs-element-keyword-in-x – Aliaksandr Maksimau Jan 21 '17 at 16:51

If the form your are updating get opened from the other form, Then in updating form class declaration declare caller as Formrun caller; Then in Init method initialize caller. caller = element.args().caller(); Then on save button clicked method after super, call this caller.dataSource().research(true);
