TWebJQXGrid advanced

I need a faster grid and I 'm testing TWebJQXGrid that is in WebCore.
Very fast, but Tms Component it's limited on powerful against "original" javascript component.

  1. How I can assign data from direct memory Json and not with "URL" property ?
  2. How to interact with original properties/events of JS Components?
    (for example, I want assign card property, or its source property or other events...)
    If is possible manage all its JS Properties is good, its very powerful.

Thanks in advance
