This is actually a failed experiment. The theory was that XAMl contains all the visual elements you need to “cross” two Silverlight objects to create child objects that resemble the parents.

However, a failed experiment is no reason to let code go to waste!

Along the way I learned some things:

• How to display XAML elements in a drop down
• How to zoom in on elements using a Viewbox and a ScrollViewer

Victor Gaudioso just shot me an email asking me how to debug a Silverlight 4 out-of-browser application where you can just hit F5. I know he is working on his latest Silverlight 4 book so he probably needs to get this in the book tonight.

To illustrate this, I am using the source code for Silverlight Bridge.

1) Right-click on the FileManager project and select Properties. On the Silverlight tab, select Enable running application out of the browser.

Here's an interesting video that gives you an idea of what working with data on the web can be like using Silverlight.

The thing that is interesting is that there are no "pages" to the application. Things just "pop out" and the objects on the screen simply adjust to allow you to quickly achieve a desired task.

The "relational data domain" is carried over from the current web application design, but the UI is totally changed. We now have to think "What if I were designing the next version of Microsoft Excel, how would the UI look?".

I just posted a tutorial on using WCF RIA Services with DotNetNuke. This tutorial demonstrates creating a simple module that allows each registered user of a DotNetNuke website to create and edit their own Task list.

This tutorial also covers two important issues that are of interest to DotNetNuke module developers; implementing WCF RIA Services in a non WAP website, and securing and segmenting data for website users.



You can try out the live sample and download all source code at this link:

This program allows users to add unlimited rows of search criteria to filter a list. This example uses the DotNetNuke Users table (normally you would not want to connect directly to a DotNetNuke core table. It is only used as an example).

Even though there is a lot of Linq code to construct the queries, there is only one trip to the database to execute the query. 

You can download the program here:

Fluent programming strives to provide for more readable code. Fluent validation provides more readable validation code. This is really important when you are building applications that have a lot of validation logic. There are two Fluent Validation ASP.NET libraries that I found:

TNValidate

Fluent Validation 

Because it was the first one I found, I decided to give Fluent Validation a try.

I just found out that the Microsoft Channel 9 program featured our DotNetNuke SketchFlow Viewer.

The link to the video is here:

http://channel9.msdn.com/shows/This+Week+On+Channel+9/This-Week-C9-IE8-most-secure-Unix-turns-40-SQL-DBA-eBook/ (they talk about SketchFlow for about 5 minutes and mention the DotNetNuke SketchFlow Viewer at about 23.18)

ADefHelpDesk does not really need an "Upgrade Advisor" but I made one anyway as a proof of concept for the DotNetNuke Core Project. There are thousands of users who do have difficulty upgrading DotNetNuke. My theory is that it should be possible to make a module that users could install before they do an upgrade that would identify potential upgrade problems.
