Ajax reorderlist not updating
You may cheer for such a powerful yet simple AJAX framework.However, things in the real world turn out to be not that simple.When it is turned on, all triggers in the content section automatically become asynchronous triggers of that Update Panel.For other information please see MSDN documentation.NET AJAX technology inevitably ends up with an application where it is hard to make changes.In this article I will present a systematic approach, or some best practices, to make the Update Panel-based ASP.This means that asynchronous triggers in the Content Template section of the Update Panel will not update a nested Update Panel.
You can contact him at [email protected] is always a central issue for software development.This is very simple: just wrap that area with an Update Panel control. You can declaratively register the trigger in the Triggers section. You can handle the asynchronous postback events the same way as the normal postback.Some controls like Repeater, Grid View, and User Control can also act as asynchronous triggers for the Update Panel with their specific or custom events such as Item Command Event. NET AJAX also allows you to register asynchronous triggers and update multiple Update Panels programmatically.Last, I will illustrate how to link asynchronous triggers with related Update Panels and how to centralize the handling of the asynchronous postback events.Decoupling asynchronous triggers and Update Panels at design time is a preliminary step to consistently specifying Update Panels and asynchronous triggers and centralizing the handling of asynchronous postback events.
The following list gives you the problematic issues around Update Panel-based AJAX applications within large-scale AJAX applications: Lacking guidelines and best practices, the inadvertent and ad hoc use of ASP.
