To add a custom button in DevExpress XAF, implement a ViewController and configure an Action such as SimpleAction or PopupWindowShowAction. This provides the exact code and lifecycle management needed for production-ready UI interactions.

Filtering a List View via a dropdown in XAF is achieved by adding a SingleChoiceAction to a ViewController. The action executes filtering logic when a user selects a status option, applying framework-aligned APIs to update the displayed data.

Managing Controller lifecycle in XAF requires proper event unsubscription during the View closing process. Following framework best practices ensures UI logic components avoid memory leaks and maintain stable interactions across application sessions.

Yes, XAF Controllers support dependency injection in .NET 8+ applications. This allows you to inject required services directly into your UI logic components, following modern framework best practices for action configuration and scope definition.

To show a modal popup window from an XAF Controller, configure a PopupWindowShowAction. This action type manages the popup view handling and user interactions, providing the framework-aligned code necessary for complex UI logic execution.

Use a WindowController in XAF for UI logic that applies to the entire window, while ViewController targets specific Views. Selecting the correct controller type ensures proper scope definition and action execution for your application interactions.
