How ASP.NET
works, continued
ŘCode uses Microsoft visual objects on the web page
§Microsoft
provides a collection of visual objects (or controls) that can be used on
the page (edit boxes, grids, buttons, calendar)
§These objects
are placed on the page in the .aspx file with HTML-like code that
specifies properties and an ID used to identify the object
§Back-end
(server) code tracks properties and methods for these objects
§When the page is
turned into HTML, these properties are applied and data is “bound” to
these objects
§When the user
clicks a control on the web page, hidden submit variables send long
binary strings to the server to specify the user’s action and
what object was acted upon
§The server then
executes methods associated with these user actions before sending
the next page
