ASP.NET

ASP.NET MVC 3 brings us new view engine called Razor. Razor view engine was made available with WebMatrix first beta. Razor brings us new and very short syntax for writing views. In this posting I will introduce you shortly ASP.NET MVC Razor view engine. (more…)

ASP.NET MVC 3 supports global action filters. Global action filters are applied to all actions in web application. By example, you can use global action filters for common security checks. In this posting I will show you how to write dummy action filter, register it as global and test it.

One of nice features of ASP.NET MVC 3 is support for multiple view engines. There will be two out-of-box view engines: one for classic ASPX-based views and one for Razor-based views. In this posting I will show you this new feature and demonstrate how to use different view engine in same project.

My last posts described new action results in ASP.NET MVC 3 – HttpNotFoundResult and HttpStatusCodeResult. Unfortunately these result have no body to send to client but there are times we need it to inform our visitor about problems the way that we don’t go out of information context where visitor is. In this example I will show you how to write your own HttpStatusCodeResult that has also body.

ASP.NET MVC 3 also introduces new action result HttpStatusCodeResult. This action result provides you way how to specify HTTP status code and status description in your controllers. In this posting I will show you how to use HttpStatusCodeResult in your real-world applications providing meaningful status code for products that were online once but are now gone and we don’t expect them to be back in future.

ASP.NET MVC 3 introduces new ViewModel property of Controller that you can use to assign different properties to the model of your view. ViewModel is dynamic by type. In this posting I will show you how to use ViewModel property in your ASP.NET MVC applications.

ASP.NET MVC 3 introduces some new action results like HttpNotFoundResult that you can use to let browser know that resource was not found. In this posting I will show you how to use HttpNotFoundResult in real-world applications.

I wrote unit tests for my ASP.NET MVC application that uses some jQuery AJAX-components. These components load data from server in JSON format. I needed to write tests for these methods to make sure that correct data is returned to client. In this posting I will show you how to use dynamic type to test JSON-based action results and therefore avoid creating DTO classes. (more…)

Using Visual Studio symbols and source files makes debugging much easier. I am specially happy about ASP.NET MVC 2 source files because I develop on ASP.NET MVC 2 almost every day. You may also find other useful symbols and source files. In this posting I will show you how to get ASP.NET MVC source to your computer and how to use it. (more…)

In one of my community projects I needed to output some listings as Excel file. As installing Excel to server is non-sense that I was easily able to avoid I found simple solution for Excel 2007 files – open-source project called ExcelPackage. In this posting I will show you hot to create simple event attendees report in Excel 2007 format using ExcelPackage.
