Silverlight Demo Content Posted (Pt1)

The first of the New Hampshire Code Camp
Silverlight Demo content has been uploaded. The content includes the simple “Hello World” code, which is just a basic Silverlight page and project, as well as the associated auto-generated Web Project. The second project is the data access demo, which illustrates a data access layer (Linq to SQL), a WCF Service which provides access to the data access layer and returns a shaped version of the data in the DAL, and a Silverlight page which shows the data in a DataGrid.

The Silverlight page in the Data Demo also illustrates the use of the Silverlight Controls’
AutoCompleteBox to do client-side filtering of the retrieved data, as well as a Line Graph from the same library. One thing that has been added since the demo is a “swinging gate” technique to use an AutoResetEvent and a background thread to load the data for the graph, in order to avoid the latency seen in the UI when the graph was being arranged inline with keyboard entry in the AutoComplete box.  The DataDemo relies on the Products table in the AdventureWorks sample database, which can be downloaded here.  As I was using a named instance of SQL Server on my machine, some updates to the connection string may be necessary – the connection string is being kept in the web project’s web.config. file.

Also uploaded are the PowerPoint slide deck and a folder of links and slides which served as reference material used in preparing the presentation. (Near) future uploads will include the use of the ASP.Net Authentication Service from a Silverlight control, and interacting with HTML content (and jQuery) through the HTML bridge. Also in a subsequent upload will be interactive PDFs of the script content I used through the presentation.

To everyone (anyone?) who was waiting for this content, thank you for your patience.

The content is available here.

  1. Hello, I came across this article while searching for help with fixing Microsoft Silverlight. I’ve recently switched internet browser from Opera to Internet Explorer 7. Just recently I seem to have a issue with loading sites that have Microsoft Silverlight. Every time I go on a website that needs Microsoft Silverlight, my browser crashes and I get a “npctrl.dll” error. I cannot seem to find out how to fix it. Any help getting Microsoft Silverlight to function is very appreciated! Thanks
