Remarks

When building an application, you may need to determine why an Action or Controller is not activated in a particular Window. This assists in finding bugs, and fixing them. For this purpose, XAF ships the DiagnosticInfo Action.

To enable this Action in Windows Forms applications, set the EnableDiagnosticActions key in the configuration file’s appSettings section to True. If you click it, a dialog window will be invoked. This window displays information on each Controller loaded to the Application Model, Actions and the current Template’s Action Containers.

For more information about DiagnosticInfo Action in ASP.NET Core Blazor applications, refer to the following topic: Determine Why an Action, Controller or Editor is Inactive.

You can supply custom diagnostic information on an Action. To do this, use the DiagnosticInfo property. Its value will be set for the AdditionalInfo item within the corresponding Controllers | Controller | Actions | Action section (see the diagnostic info snippet below).
