OnTheFlyPostBack® for fast AJAX callback
Developed in 2002, Intersoft’s patented OnTheFlyPostBack® is an AJAX-like
engine implemented in all WebUI Studio products. This sophisticated engine powers
many WebGrid features which require server callback, enabling transparent data retrieval
from the server in the background as users move between pages. Unlike many other
AJAX implementations, OnTheFlyPostBack® fully supports all ASP.NET framework
scenarios, and automatically saves and restores control viewstates.
Child row state preservation
With RestoreExpandedChildRows enabled, WebGrid will remember and restore
the checked and expanded states of all rows during a flypostback action. Users can
take any action, such as sorting, refreshing, or filtering – WebGrid will faithfully
restore all rows to their previous condition. This unique WebGrid capability applies
to all rows, no matter how deeply they are nested, preserving the integrity of your
user’s current view of their data regardless of the actions they take.
