I'm using Visual Studio 2008 and ASP.NET Web Forms to create a UserControl for a SharePoint (2010) site. The UserControl is loaded through SharePoint WebPart.Everything works fine so far, but i need to use jQuery in my UserControl. So i downloaded jQuery and saved that in the following folder:\[code\]C:\inetpub\wwwroot\wss\VirtualDirectories\80\[/code\]So i saved jQuery (for now) in the root directory.In my UserControl code behind i added the following line in the \[code\]Page_Load\[/code\] method:\[code\]ScriptLink.Register(this.Page, "~/jquery.min.js", false);\[/code\]But when i re-build my UserControl and load it on a SharePoint page it still says: \[code\]The value of the property '$' is null or undefined, not a Function object\[/code\].So basically jQuery isn't found.Anyone any idea what i'm doing wrong?
