• ASP.NET Dynamic Data Preview Available

  A few months ago we released an ASP.NET 3.5 Extensions Preview that contained a bunch of new features that will be shipping later this year (including ASP.NET AJAX Improvements, ASP.NET MVC, ASP.NET Silverlight Support, and ASP.NET Dynamic Data). The ASP.NET Dynamic Data support within that preview provided a first look at a cool new feature that enables you to quickly build data driven web-sites that work against a LINQ to SQL or LINQ to Entities object model.  ASP.NET Dynamic Data allows you to automatically render fully functional data entry and reporting pages that are dynamically constructed from your ORM data model meta-data.  In addition to supporting a dynamic rendering mode, it also allows you to optionally override and customize...

• New ASP.NET Dynamic Data Support

  The ASP.NET 3.5 Extensions CTP we shipped this past weekend contains a bunch of great new features. One of the cool new features is something we call "ASP.NET Dynamic Data Support".  In a nutshell this enables you to really quickly build data driven web-sites that work against a LINQ to SQL (and in the future LINQ to Entities) object model - and optionally allows you to-do this without having to build any pages manually. The best way to see this in action is to watch David Ebbo's awesome 17 minute screen-cast : You can also follow the steps below to easily get started and use the dynamic data support: Step 1: Create a ASP.NET Dynamic Data Site: Once you have the ASP.NET 3.5 Extensions CTP release installed, you can use VS 2008...

• LINQ to SQL (Part 9 - Using a Custom LINQ Expression with the <asp:LinqDatasource> control)

  Over the last few weeks I've been writing a series of blog posts that cover LINQ to SQL. LINQ to SQL is a built-in O/RM (object relational mapper) that ships in the .NET Framework 3.5 release, and which enables you to model relational databases using .NET classes. You can use LINQ expressions to query the database with them, as well as update/insert/delete data. Below are the first eight parts in this series: Part 1: Introduction to LINQ to SQL Part 2: Defining our Data Model Classes Part 3: Querying our Database Part 4: Updating our Database Part 5: Binding UI using the ASP:LinqDataSource Control Part 6: Retrieving Data Using Stored Procedures Part 7: Updating our Database using Stored Procedures Part 8: Executing Custom SQL Expressions In...

  Over the last few weeks I've been writing a series of blog posts that cover LINQ to SQL. LINQ to SQL is a built-in O/RM (object relational mapper) that ships in the .NET Framework 3.5 release, and which enables you to model relational databases using .NET classes.

• The asp:ListView control (Part 1 - Building a Product Listing Page with Clean CSS UI)

  One of the new controls in ASP.NET 3.5 that I think will be very popular is the <asp:ListView> control. The ListView control supports the data editing, insertion, deleting, paging and sorting semantics of higher-level controls like the GridView. But - unlike the GridView - it provides you with complete control over the html markup generated. The ListView control, when combined with the new Web Designer and rich CSS support in VS 2008 , enables you to build much cleaner HTML UI. Over the next few weeks I'll be putting together several blog posts that show off how you can use it. Building a Products Catalog Page For today's blog post we are going to start simple and just build a basic product catalog listing page like below: This products...

• Using LINQ to XML (and how to build a custom RSS Feed Reader with it)

  One of the big programming model improvements being made in .NET 3.5 is the work being done to make querying data a first class programming concept. We call this overall querying programming model "LINQ", which stands for .NET Language Integrated Query . LINQ supports a rich extensibility model that facilitates the creation of efficient domain-specific providers for data sources. .NET 3.5 ships with built-in libraries that enable LINQ support against Objects, XML, and Databases. What is LINQ to XML? LINQ to XML is a built-in LINQ data provider that is implemented within the "System.Xml.Linq" namespace in .NET 3.5. LINQ to XML provides a clean programming model that enables you to read, construct and write XML data. You can use LINQ to XML to...

• LINQ to SQL Debug Visualizer

  Probably the biggest programming model improvement being made in .NET 3.5 is the work being done to make querying data a first class programming concept. We call this overall querying programming model "LINQ", which stands for .NET Language Integrated Query . Developers can use LINQ with any data source, and built-in libraries are included with .NET 3.5 that enable LINQ support against Objects, XML, and Databases. Earlier this summer I started writing a multi-part blog series that discusses the built-in LINQ to SQL provider in .NET 3.5. LINQ to SQL is an ORM (object relational mapping) implementation that allows you to model a relational database using .NET classes. You can then query the database using LINQ, as well as update/insert/delete... Posted Aug 01 2007, 01:23 AM by ScottGu's Blog Filed under: ASP.NET, Data, LINQ, SQL Server, Visual Studio, .NET
