9. MicroBS – server side viewstate Data is saved on session, without serialization Identical use compared to client-side Viewstate Garbage collector tracks down opened windows with javascript and cookies Support perisistent viewstate (state of specific controls can be serialized to disk) References are shared (several controls can access same object) Using less resources on network Using more resources on server “Back” in browser does not work

10. MicroBS – Data filter Database table fields can be used to create query or for data binding Queries are dynamically created DataFilter can be serialized (saved) DataFilter support binding to another DataFilter, allowing creation of complex queries gradually

11. MicroBS – Template web controls Template Edit control - automatization of simple edit forms Template Query control - search Browse dijalog (client-side) Formatted TextBox External XML file describing structure ASCX = XML! Precompiled and cached

12. MicroBS – Web components Advanced container with decision logic for several templated web controls Component coordinator is controling actions Automated security based on permissions or statuses; every object is set up as read-only; action buttons (add, update, delete) are hidden Types: Details, Attachments, Categories, Attributes, Search, etc. Coordinator template contains components order. Manipulation of all data types controls only one ASPX page!
