ASP.NET Dynamic Data 4.0 Preview 4 (UPDATED 6/26)

NOTE: These previews contains features that may not be in the next version of the framework. These previews are not production quality and should be used at your own risk

This solution contains a number of samples showcasing new Dynamic Data and data-bound control features that are being planned or considered for the next version of ASP.NET.

Refreshed 6/26

• DomainDataSource had errors updating foreign keys
• Cannot edit many to many relationship with table per type inheritance
• Better exception handling

The ASP.NET Dynamic Data 4.0 Preview 4 contains a number of different projects:

• DynamicDataVNextSamples - This contains a variety of samples that show off the various new aspects of Dyamic Data Preview 4.
  • DynamicDataSamples – This is the primary project sample that shows most of the new functionality that has been added to Dynamic Data since .NET 3.5 SP1. The default.aspx page highlights many of the new items that are being added in .NET 4, in particular: Filter Templates, Entity Templates, Field Templates, Many to Many Relationships, Enumerations and Inheritence.
  • SimpleDynamicDataSamples - This sample project demonstrates new functionality that allows Dynamic Data field templates to be used by applications without any requirements (no data model is required (but can be used), no routing is required, no registration globally is required. Just take a data control and use the code DataControl.EnableDynamicData. This automatically gives the data control automatic validation and supports the attributes in System.ComponentModel.DataAnnotations.
  • DataSourceQueryExtenderSamples – One of the new big features in ASP.NET 4 is the QueryExtender control. This control allows very simple filtering for data source controls for common operations that developers want to do like search for a string across columns, check if the value of a column is in a certain range and other operations. These samples also show the DomainDataSource which is a new ASP.NET data source control that will be used to access .NET RIA Service Domain Services. See the .NET RIA Service section at the bottom of the document for how to download and install the tooling support for Domain Services.
  • ADO.NET DataServices - This project contains a sample DataServiceLinqDataSource which is an ASP.NET data source for accessing ADO.NET Data Services from web pages.

• ProjectTemplates - These are starter projects that can be used to build brand new applications that have support for all the new features in the Preview. To start just copy the directory that supports the data model that you are using to a working folder, create a data model and register it in Global.asax.
  • DomainServiceProject - This is for projects using the .NET RIA Domain Service for the data access layer.
  • EntityFrameworkProject - This is for projects using Entity Framework models for the data access layer.
  • LinqToSqlProject - This is for projects using Linq to SQL for the data access layer.

To run: Open one of the above projects in Visual Studio 2008 and run the web site.

To build your own sites: Start with one of the projects in the ProjectTemplates directory to get an empty Dynamic Data site, add a database, create the appopriate data model for the project, register the data model in Global.asax and run.

For more information view the README.doc which is available as part of the Preview4 download and seperately.
