Partial Updates

IntraWeb supports partial updates. What are partial updates? They are a revolutionary update model that will greatly improve your application's performance.

The update mode can be controlled by a property of every form, called UpdateMode. According to this property, IntraWeb will use either the standard update mode which updates all the form, or will update only the controls that need refreshing. The partial update mode is strongly recommended over slow connections, to significantly increase the speed of your application.

When a screen is repainted using partial updates, only a small delta packet is sent to the browser. This reduces bandwidth and creates a faster and more responsive application to the end user. It also eliminates the page flash and resetting of scrollbars.

Partial update is the most innovative technology in web development. However, due to the heavy use of scripting technologies, this update mode is available only on latest browsers and only in HTML 4.0 mode.
