Remarks

We do not recommend that you use the DoExecute and other methods to execute Actions because such methods can contain UI-specific code. You can refactor your Action’s event handlers and extract the required code into separate methods. Call these separate methods directly without triggering UI-related Action code.

Programmatic execution of custom and built-in Actions is acceptable in rare advanced scenarios, for example, if you:

• Create a custom Action Container and call the DoExecute method inside the Action control. In this context, you have complete control over your custom code and can execute any action. Remember to trigger life-cycle events for your actions (such as Execute).
• Add new ways to invoke Actions from the UI (for example, support keyboard or voice control).
• Reuse a built-in Action in a specific context where you would need to write a lot of code to re-implement the Action’s internal business logic.

For more information on how to implement such complex requirements, refer to the following materials:

• XAF - How to execute Actions programmatically.
• “Related GitHub Examples” section of the SimpleAction.DoExecute topic.
• “Related GitHub Examples” section of the ParametrizedAction.DoExecute(Object) topic.
