Dataset constraints

A question please.

Lets say I have a grid with its datasource as a dataset with three columns
in it; UserID (an auto generated ID), LastName and FirstName. Additionally,
lets say I want to restrict the user from entering two records with the same
last name and first name. I have created a constraint for LastName
FirstName in the dataset but I would like a different message than the
default message I get when the constraint is violated. Is there a way for
me to do this?

try
{
//whatever
}
catch (ConstraintException ex)
{
throw new ConstraintException("whatever");
}

Yes, but where? That is, where do I place a try catch statement? In what
event?
