I’m working with referencing user controls on my ASPX page and I’m wondering what the difference is between these two page directives.
@Registeris the more commonly used directive. You use this when you want to use a user control in your aspx or ascx page declaratively.@Registerassociates the control with a specific prefix and you can then use it in your markup.@Referenceonly tells ASP.NET to compile the other control when your aspx or ascx page is compiled. That makes sure it is available at run-time and can be added to your control hierarchy programmatically. This is less common since dynamically changing user controls at runtime is not comon.Here’s a good blog post about it.
