Community Server module for embedding Silverlight 1.1 to posts

I figured I just jump into it; creating a Community Server 2007 module for rendering Silverlight content.

It all started up yesterday as a simple thing, but I figured that I didn’t feel comfortable with the way the plugin system worked in Community Server, so I created a small abstraction from it to make it feel more right for me. 🙂   It’s all based upon attributes instead of hooking up events. The reason I started doing the abstraction was that I have a couple of modules I need in the pipeline and wanted to simplify stuff I will be needing for all modules, such as filtering for ApplicationType.

The module code turns out as follows (I’ve attached the entire project with source and binaries)

  [Module("SilverlightModule")]
  public class SilverlightModule : BaseModule
  {
    private static readonly string SilverlightScript = "Silverlight";
    private static readonly string SilverlightApplicationScript = 
                        "SilverlightApplication";

    [Method(MethodType.PreRender)]
    [MethodType(MethodType.PreRender)]
    [ApplicationType(ApplicationType.Weblog)]
    [ApplicationType(ApplicationType.ContentManagement)]
    public string Render(string protocol,string xamlUri)
    {
      string completeUri = protocol + ":" + xamlUri;

      Page page = MethodContext.Current.Page;

      if (!page.ClientScript.
          IsClientScriptBlockRegistered(SilverlightScript))
      {
        page.ClientScript.
          RegisterClientScriptBlock(  typeof(SilverlightModule), 
                        SilverlightScript, 
                        Resources.Silverlight, true);
      }

      if (!page.ClientScript.
          IsClientScriptBlockRegistered(SilverlightApplicationScript))
      {
        page.ClientScript.
          RegisterClientScriptBlock(  typeof(SilverlightModule), 
                        SilverlightApplicationScript, 
                        Resources.SilverlightApplication, 
                        true);
      }

      Guid applicationGuid = Guid.NewGuid();

      string hostName = "SilverlightControlHost_"+applicationGuid.ToString();

      completeUri = completeUri.Trim();

      return 
      "<div id="" + hostName + "" style="background-color:Black" >" +
      "<script type="text/javascript" style="background-color:Black">" +
      "createSilverlight(""+completeUri+"",""+applicationGuid.ToString()+"");" +
      "</script>" +
      "</div>";
    }
  }

Installation instructions :

Copy the binary (DoLittle.CS.Modules.dll) into the bin directory of your Community Server installation. Add the following line to your communityserver.config file :

<add name=”SilverlightModule” type=”DoLittle.CS.Modules.SilverlightModule, DoLittle.CS.Modules”/>

Then you have the SilverlightModule up and running.

To use it you simple write [SilverlightModule: protocol:uri] in your editor.

protocol : http, https
uri : The uri for the XAML to use

Sample : [SilverlightModule: http://www.dolittle.com/Silverlight/3D/Page.xaml]

Remember to use the unlink button for the Uri. Community Server editor and most other editors will automatically translate the Uri and add a href around it.
