I have looked at cascading dropdown lists with WebMatrix previously, but the approach I featured demonstrated the use of jQuery Templates. At the time, the jQuery Templates project looked promising, but since then, the jQuery team have decided not to take them beyond beta stage. So the reason for this article is to illustrate a more "traditional" jQuery approach to managing cascading dropdown lists when developing ASP.NET Web Pages using WebMatrix.

Version 2 of the Web Pages framework includes a new validation framework. Included are a number of specific validators that cover common scenarios such as validating for presence, data type or range. It may be however, that you want to create your own custom validator to test for something that isn't covered by the existing validators, or to combine multiple tests in one composite validator. Fortunately, the Web Pages team have made the validation system extensible so that you can create your own validators.

If you want to build AJAX powered rich client interfaces with ASP.NET Web Pages, you will work with JSON - a lot. You might also be attracted to the Entity Framework for your data access technology. There are some special considerations to take account of when serialising Entity Framework objects to JSON for use in Web Pages applications. This article explores some of the issues you will encounter through the example of a simple To Do list manager.

There are a huge number of articles and blog posts on persisting data between user requests in ASP.NET. However, the ASP.NET Web Pages framework introduces a couple of additional mechanisms so this article explores those, as well as reviewing some of the standard approaches already available to Web Pages developers from other parts of the ASP.NET framework.

The built-in Web Pages routing system offers a fair degree of freedom in terms of how friendly URLs can be constructed and managed. However, the major limitation with the standard routing mechanism is that it relies on matching segments of the URL to files on disk. ASP.NET MVC and Web Forms enjoy a much more flexible routing system. This article looks at a Package that brings full ASP.NET routing control to Web Pages and examines how to use it.

Web site skinning is a concept where by a web application user can personalise their experience, by choosing from a selection of prepared themes or skins. Each theme or skin might offer a different design, or content, or both. ASP.NET Web Forms has included a comprehensive Themes framework since version 2.0. WebMatrix developers can find Themes management functionality in the ASP.NET Web Helpers Library package available through the Package Manager. This article looks at how the Themes helper works.

Since I published an item covering Code First development with Entity Framework and WebMatrix, I have had a few requests to provide a guide to working with the Entity Framework from a database first point of view. This post answers those requests and provides a step by step guide to getting up and running with a WebMatrix web site based on the Northwind sample database that comes with SQL Server CE 4.0.

A nugget that has remained partially hidden from view within the Web Pages framework is the HtmlHelper class. Parts of this class peek out in the template sites provided in WebMatrix where validation is performed and related messages displayed, but a vast range of methods designed for rendering form inputs are often overlooked in tutorials, blog articles and books (mine included). This article provides an overview of Web Pages HTML Helpers, and digs into one or two in more detail.

The existing data access story for WebMatrix is the Database Helper. Microsoft's recommended data access technology going forward is the Entity Framework (EF). This article explores how to use the Code First capability offered by EF within an ASP.NET Web Pages application.

A problem inherent in the existing version of the WebGrid is that it is not very efficient when it comes to paging data out of the box. If you have 10,000 rows of data, and you want to display 10 rows per page, all 10,000 rows are retrieved from the database for each page. The grid works out how to only show the current 10, and wastes the other 9,990 rows. That's a fair sized overhead on each page. Ideally, you should only retrieve the data you need for each page. This article examines how you can do that with the existing WebGrid and a SQL CE database, while still maintaining sorting capabilities.
