问题 I'm looking for a way to automatically set the initial focus on a Silverlight UserControl to a specific control.

问题 UPDATE: An alternative title for this could be: How do I call javascript from my silverlight 2.0 application. Here is a quick question for all you Silverlight gurus.

问题 Is is possible to create silverlight content in C# using Visual Studio 2005 Professional or Visual Studio 2008 Express Edition? I can't find an answer on Microsoft's web site.
