I’m pleased announce that I’ve posted a number of SharePoint 2010 and Silverlight 3.0 code samples to MSDN Code Gallery here. These are updates of the solutions shown at SharePoint Conference 2009 in the talk, “Advanced Development for Silverlight 3 in SharePoint 2010”, which were more recently shown in an MSDN Webcast. A recording of the webcast, “Developing Rich Solutions in Silverlight for SharePoint 2010”, is available here.
The samples and demonstrations include:
SharePoint and Silverlight from Scratch
This walkthrough was presented only in the webcast to show how to get stared developing in Silverlight for SharePoint 2010. The sample includes only the snippets (in Visual Studio snippet format); it will be necessary to watch the webcast to see how to use them.
Picture View Web Part
This is a Silverlight web part that shows a slide show of images stored in a SharePoint picture library. This demonstrates how to use the HTML bridge to reduce the number of round-trips to the server. In this case, the server side web part passes the URL’s of the pictures to Silverlight in a hidden form field, removing the need for the Silverlight application to query the server for the list of pictures.
Paged List View Web Part
This is a Silverlight web part that shows a grid of data from a SharePoint list. It allows paging, sorting and filtering, and only loads an n-row page at a time to allow viewing a large data set without downloading the whole thing to Silverlight. In addition to loading the first “page” of data in a hidden field (like the Picture View web part) , it obtains additional content using ADO.NET Data Services and SharePoint’s new RESTful interface.
NOTE this release does not include the target list, and the sample will not run without it. A future release may include a matching list definition with sample data.
Video Field Control
This adds a Video field to SharePoint, using Silverlight applications to view and select the video. The actual field simply stores the URL of the video. The Silverlight display application is very simple, and just plays the video based on this URL. The selector application is more interesting as it uses the client object model to provide a simple browsing and preview feature in which the user can select a site, library and video to be shown.
Connected Silverlight Web Parts
This sample includes a pair of web parts – a source and target. When connected via the web browser, text entered into the source web part will appear on all targets as it is typed. This shows how to use SharePoint’s web part connection mechanism – which runs on the server side – as a broker to connect the Silverlight applications. The Silverlight applications communicate using the new Silverlight 3.0 Local Messaging API.
