    This will be a pretty short and sweet blog post, but the issue that I describe caused me enough headaches, and was hard enough to ‘Google’ that adding more ways to get there is in and of itself worth it. The problem I ran into was with a Silverlight 4 RIA Services application which utilizes Windows Authentication and needs to run as an out of browser application. The application needed to get detailed user information in order to properly construct the initial application user interface. The problem is that the Authentication Service call was timing out whenever I ran the application, and my RIA Service was never even executed.

    This is going to be a quick post just to get the solution out there for people who may be running into this issue.  If you're like me, you host your sites on remote servers and you don't always have direct control over the 'IIS settings’ of the site.  This can be especially difficult if you are trying to deploy something like a Silverlight 4 RIA Services application.  The problem I ran into this evening was the following, I got the site up and running and everything looked good, but when I went to launch the administrative application which is powered by Silverlight 4 RIA Services, I noticed that none of my data was coming back and saving didn't work properly.

    In Part 1 of this series, Benjamin Gavin designed the data model and started building out the administrative application. In this article, he continues building out the client application by adding Question maintenance, then he adds some custom validation to Categories and Questions and builds out the public facing component of the application.

    In this article, we walked through the addition of Question maintenance to the administrative application. We also covered some basic client and service side validation rules and built out a public interface to display our FAQ data. The application is fairly simple, but it allowed us to show a complete and functional Silverlight application with a rich administrative user experience. Improving the public facing experience is just a matter of some clever styling, and the client UI gracefully degrades when JavaScript is unavailable. We have met all our client requirements and provided the administrative staff with a pleasurable maintenance experience.

  • Silverlight MVVM Drag & Drop

    Benjamin Gavin has published a new series on Drag and Drop. In the first two articles, he covers using Drag & Drop for both the ListBox and the TreeView controls, while in the third one he ties the two technologies together to provide a rich UX for editing categories and an associated item, in this case, Images.

    The goal of the application will be to present the TreeView of categories on the left-hand side of the screen, and a ListBox on the right-hand side which represents all images for the currently selected category.  The ListBox will allow the user to drop images into it for addition to the category, and we will also provide a link that launches a standard multi-select OpenFileDialog window to upload files.  As with the previous example, categories can be added, removed and reordered within the tree.  The images in the list can also be reordered by simple drag & drop operations and images can be dragged from the ListBox onto another category to move the image from one category to another.
