Release Notes

The PartialUpdatePanel provides real partial rendering of ASP.NET pages.
By using this control you can get a performance improvement compared to ASP.NET AJAX UpdatePanel, because not all page data are transfered. Only a minimal set of data is transfered between client and server to let your UserControl run and make it fully functionable.

Usage scenarious

Example scenarious where you better use the PartialUpdatePanel might be
  • Autonomous sections of your page that require PostBack-support but not the environment information of the whole page (e.g. data lists with paging support where the user can browse through news, feeds, mails, etc.)
  • User feedback when your control have to complete long operations. In this case use a PartialUpdatePanel with render method "Clientside". The surrounding page will be displayed with a waiting message. The user get's feedback that something is going on he has to wait for.
