Setting up WebForms ASP.NET tags
About this task
To use WebForms with .NET 1.1 SP1, you must register WebForms tags in each Web page by modifying the Page Template. Refer to the documentation portal for details.
To use WebForms with .NET 2.0 or higher, register a server control in the web.config file of your Web application, if server controls have been enabled for the SDL Tridion suite. After you have registered the server control, you can then use the tags using the twf: prefix. This topic explains how.
