Two alert readers of my article An Extensive Examination of User Controls (Tommy Goddard and Aaron Stonerock) have written in to let me know that there's an easier way to add a User Control to an ASP.NET Web page in Visual Studio .NET than manually adding in the <%@ Register %> directive and accompanying declarative syntax: simply drag and drop the User Control from the Solution Explorer onto the Design view of an ASP.NET Web page. VS.NET will automatically add both the <%@ Register %> directive and the declarative syntax. I've since sent in an update to my MSDN editor.
Sadly, I was informed of this neat way of adding User Controls to a page prior to the article's publication. Bob Mohler, a student in my ASP.NET Programming II course, pointed this technique out to me back in the first week of March. I had completed the article by then, but it slipped my mind to have the article updated prior to publication. Anywho, since Bob alerted me to this new techinque, I've not written <%@ Register %> save for this blog entry! :-)
Thanks Bob, Tommy, and Aaron!
