What triggers ConstraintException when loading DataSet?
.net, c#, dataset
Solution
There is a property called RowError you can check.
See http://dotnetdebug.net/2006/07/16/constraintexception-a-helpful-tip/
Edited to add this link showing iteration of rows to see which had errors.

Problem
How can I find out which column and value is violating the constraint? The exception message isn't helpful at all: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.
