As I see it, the messages displayed by Genexus have the class "gx-warning-message" or "gx-error-message" depending on whether it is through an error rule or the msg command.
Since sometimes when we work in Webpanels, we want to show errors or warnings, is there any way to choose the way we want to display a message?
Daniel,
No, it is not possible to show an Error message (programmatically) from a WebPanel.
Only the "msg" command is allowed and not the "error" command.
To enable this scenario, you can either create a UserControl for yourself or use an existing one
