With this example we demonstrate 3 new methods
1. navButtonAdd - with help of this method we can add custom buttons in page bar.
2. GridToForm - this method fill the form data from grid with a given row id and form id.
3. FormToGrid - this method fill the Grid row with data from a given form id.
Select a row. Then click a edit button. Try to change some values in form and then click Save button.
Note: data is not saved to the server.
