.NET user controls provide an endless number of possibilities for your Umbraco installation. With user controls you can harness the power of .NET code inside your templates and content pages. If you can create something in a custom .NET application inside a user control, it's also possible to render/function it in an Umbraco rendered page.
Remember to have a <form runat=“server”/> tag in your template that encapsulates the user control. If you don't, the user control will not work.
This section shows how to extend the user experience by adding dynamic form functionality, as well as how to create custom data types for user input in the backoffice.
