Cannot use a lambda expression as an argument to a dynamically dispatched operation

18 September 2012 08:08

LINQ ASP.NET MVC ASP.NET Web Pages WebMatrix

Since the introduction of the Web Pages framework, ASP.NET has been making use of the dynamic type introduced in C# 4.0. Along with that comes some new error messages which at first glance don't make a lot of sense - mainly because they are unexpected. I have already looked at how dynamics do not support extension methods, and a recent question in the ASP.NET forums illustrated another way in which the dynamic type can catch you out.

Optimising ASP.NET Web Pages Sites - Bundling And Minification

15 September 2012 17:05

ASP.NET Web Pages WebMatrix

ASP.NET 4.5 saw the introduction of new features for improving the performance of web sites. Delivered within a new library called System.Web.Optimization, bundling and minification enables you to combine multiple JavaScript or CSS files into one bundle, and to minify them thereby reducing the number of HTTP requests that browsers have to make, reducing the size of the files, and improving performance of the site overall, especially over slower (read 3G) networks.

WebMatrix - jQuery Cascading Dropdown Lists

08 September 2012 09:56

jQuery ASP.NET Web Pages WebMatrix

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.

ASP.NET Web Pages - Creating Custom Validators

31 August 2012 14:33

ASP.NET Web Pages 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.

More Flexible Routing For ASP.NET Web Pages

01 February 2012 21:52

ASP.NET Web Pages WebMatrix Razor

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.

HTML Helpers For Forms In Razor Web Pages

25 December 2011 11:27

HTML ASP.NET Web Pages WebMatrix Razor

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.
