How is LiveControls different from .NET 2.0 Client Callback Manager?
• .NET 2.0 Client Callback Manager provides a basic Remote Procedure Call (RPC) machanism from the browser to the server. PowerWEB LiveControls for ASP.NET adds: • development UI support with full-featured Web Controls (standard properties, methods and events) that generate necessary JavaScript and event hooks • interpretation of all changes made in code-behind and the updating of “dirty” client elements (Live controls, Microsoft controls, and compatible 3rd party controls) without refreshing the page • complex operations such as updating databound grids and lists as source data changes • automatic ViewState management • broader browser compatibility not limited to XmlHttp-equiped browsers, with automatic degradation of callback techniques to match browser capabilities • LiveControls can enable complex application development where similar projects using Client Callback Manager may exceed budgets because of the large amount of javascript programming required.
