Question: Within SalesLogix I have created a custom business rule that needs to be executed before saving a record.  If that custom rule fails I would like to display a custom message to the user explaining why it has failed to save.  So far, I have added a C# code snippet to the BeforeInsert or BeforeUpdate Event that produces a new ApplicationException if that business rule fails.  The record won't save, which is what I want, but the message that pops up is confusing to the user:

'An exception occurred executing the dynamic method Ticket.OnBeforeInsert.'

Is there a way that I can create a custom exception message to display to the user?

Answer:  To do this you will need an optional message as a parameter.  Here is an example:

throw new Sage.Platform.Application.ValidationException("Field xxx is required.");

This pops a java alert box with your message to the user and halts execution of the save.
