Add a Simple Action

You can add a Single Choice Action to a Controller inthe following ways:

  • In design time (for the .NET Framework projects): drag and drop the SimpleAction item from the Toolbox (the XAF Actions section) onto the Controller’s Designer area.
  • In code: see the Add a Simple Action (.NET 6+) tutorial.

Alternatively, you can use the ActionAttribute to convert a business class’ method to an Action (see How to: Create an Action Using the Action Attribute).


CodeRush allows you to add Actions and Controllers with a few keystrokes. To learn about the Code Templates for XAF, refer to the following help topic: XAF Templates.

Set the IModelActionWeb.IsPostBackRequired property to true to send a postback when a user executes an Action in an ASP.NET Web Forms application. For example, for Actions that download files or change the application’s language.
