Registering of controls in web.config

Question

Is it possible to register controls, aside from:

<%@ Register Tagprefix="CustomSearch" Namespace="SomeAssembly.WebControls" 
   Assembly="SomeAssembly.WebControls, Version=11.0.0.0, Culture=neutral, 
   PublicKeyToken=71e9bce111e9429c" %>

within the web.config file, like you can with a normal ASP.Net web site? I tried this, but SharePoint keeps complaining that it cannot find the control?

Answer 1

If you are trying to register a variety of User Controls, you cannot do it that way. A user control requires that you reference it's .ascx file in order to use it, like this:

<%@ Register Tagprefix="CustomSearch" Tagname="SearchBox" src="~/_controltemplates/customsearch/searchbox.ascx" %>

The above allow the use of this: <CustomSearch:SearchBox ID="SearchBox1" runat="server" />

Whereas in your provided example, that registers controls, which also will allow the use of the above example, but the difference being that the controls don't have "visual" files like .ascx or .aspx.
