Loading several DataTables into a DataSet using DataRelations when there are invalid constraints causes the error message “Failed to enable constraints. One or more rows contain values….”.

Solution is documented here

foreach (DataTable dt in dataset.Tables)
{
	if (dt.HasErrors)
	{
		Console.WriteLine("ERRORS IN : " + dt.TableName);
		foreach (DataRow dr in dt.GetErrors())
		{
			Console.WriteLine(dr.RowError);
		}
	}
}
