Validate End User Permissions in the Application
If you need to restrict end user access to specific areas or operations of an app, you must validate their permissions using Roles to control access to screens, screen elements or actions.
To restrict access to a screen of an app, in the Roles property of the screen select the end user Roles that can view the screen.
To restrict access to screen elements or actions of a screen, use the Check<Role_name>Role action or function to determine if the end user has the necessary Role.
In Traditional Web
If you only need to check for a Role once in a screen, you can use a Check<Role_name>Role function directly in the Condition of an If widget.
If you need to check for the same Role more than once in the same screen, follow these steps:
-
In the Preparation of the screen, add the Check<Role_name>Role action, and set the UserId to
GetUserId().
-
Use the Check<Role_name>Role.HasRole output, to hide interface elements and restrict access to actions, for example:
-
Hide or display interface elements using an If widget with a
Check<Role_name>Role.HasRoleCondition.
-
Block or allow executing actions by hiding the Buttons or Links that call the actions, using an If widget with a
Check<Role_name>Role.HasRoleCondition.
