Folders and files

The following table describes the files and folders created in the root directory of ASP. NET Dynamic Data Network.

default. aspx	A default homepage displays all registered data models and table names. A hyperlink is used to display the content of the selected table.
global. asax	contains a method for registering the metadata model of a database instance, and add a routecollection object
site.css	display style of sites and controls
site. master	site template
Web. config	Configuration file to load necessary Class Libraries

1. Add a metadatabase instance model (LINQ-TO-SQL)

Chart 5

1. Register this metadata model and open global. asax

Public Static VoidRegisterroutes (RoutecollectionRoutes ){

MetamodelModel =New Metamodel();

// Model. registercontext (typeof (yourdatacontexttype), new contextconfiguration () {scaffoldalltables = false });

Routes. Add (New Dynamicdataroute("{Table}/{action}. aspx"){

Constraints =New Routevaluedictionary(New{Action ="List | details | edit | Insert"}),

Model = Model

});

// Routes. Add (New dynamicdataroute ("{table}/listdetails. aspx "){

// Action = pageaction. List,

// Viewname = "listdetails ",

// Model = Model

//});

// Routes. Add (New dynamicdataroute ("{table}/listdetails. aspx "){

// Action = pageaction. details,

// Viewname = "listdetails ",

// Model = Model

//});

}
