  Let me start by saying that I hope you won’t run into this one and that you probably won’t.

• Custom progress indicator for UpdatePanel

  Apr 10, 2011

  In ASP.NET the UpdatePanel can help you create an AJAX experience very fast and easy. It is typical to provide some visual element in the page that indicates that the AJAX request is been processed. This can be an animated image, a simple text message, a pretty modal box with a nice shadow effect - anything that does the trick and tells the user that the page is not broken but it’s busy.

• SystemWebCompanion

  Mar 19, 2011

  In many ASP.NET web applications, there are some small bits of code that you have to write over and over again. They’re too small so you never bother to refactor them out as a reusable dll. After all they are so small that it’s very fast to create from scratch again. They end up as a Utils.cs file somewhere in your project, probably repeated in all your projects in one form or another.

• ASP.NET IsMobileDevice and how it works

  Mar 12, 2011

  In ASP.NET, you can use the IsMobileDevice property in the Request.Browser object of the current request to figure out if the user is calling your application using a mobile device.

• Getting the client's timezone in ASP.NET

  Dec 1, 2010

  The client (browser) doesn’t send any information to the server regarding the client’s timezone. It’s just not supported. One might try to guess the timezone from the culture or even try to guess it from this new geo-location feature. Maybe in the future there will be a new header like “X-Client-Timezone: UTC+1” but for the time being a good approach is the following.

• First Umbraco experience

  Aug 15, 2010

  Today I played a bit with Umbraco for the first time. I mostly focused on its multilingual support, which is a feature I usually expect from a CMS.

• Dynamic PNG Image Generation with ASP.NET

  Jun 25, 2010

  I had created a small web app in MonoDevelop that created a png image on the fly. Porting the app to Windows .NET 3.5 with Visual Studio 2008 was almost painless, but it did include two unexpected incident. The first one was… well the app didn’t run anymore, showing the dreadful “A generic error occured in GDI+”. A bit of a research lead to this article here. Apparently the problem occurs only with PNG images. The stream that you write the generated image to needs to be seekable and I guess in Mono the Response.OutputStream is seekable but in .NET it’s not. The solution is to use an intermediate MemoryStream to write the image to and then dump that stream on Response.OutputStream.
