使用Silverlight为DotNetNuke创建模块.doc

Why DotNetNuke and Silverlight? Silverlight?is an application that runs in the web browser. It has its own operating system and one would be tempted to create solutions completely using Silverlight. For example, lets assume you wanted to create a?Photo Gallery. Soon you would realize that you need a method to allow an administer to upload pictures to the gallery. Also, you need to implement security to only allow the administrator to upload pictures. You would also want to give the administrator the ability to create multiple picture albums. Implementing this functionality will usually consume more time and resources than the Silverlight Photo Gallery itself.? The logical solution is to leverage the free open source?DotNetNuke Portal Framework?and create a DotNetNuke Silverlight module, because DotNetNuke has an extensive user and roles management system. This will allow you to concentrate on the primary functionally of your Silverlight application. Challenges with DotNetNuke Silverlight modules Silverlight 1.0 applications are primarily comprised of XAML files and JavaScript. DotNetNuke allows for a single module to be placed on a page multiple times. This can cause undesired behavior as Silverlight requires a uniquely named DIV for each Silverlight control on the page that must be initialized by JavaScript. The JavaScript would not know the name of this DIV tag because it is created at run time. The solution to this is to dynamically create the code that injects the Silverlight module on the page. Creating a Silverlight module To best explain how to create a DotNetNuke Silverlight module, it is helpful to first create a normal Silverlight application. To start, we will open?Microsoft Expression Blend 2?(or higher). From the File menu, select?New Project... . From the Create New Project menu, select?Silverlight Application (JavaScript), enter a name and click?OK. From the toolbox select the?TextBlock?control. Hold down the mouse button as you draw a rectangle. Ente
