Jeff,

>That makes perfect sense. The Validation is just looking at one record. I made the changes, now the next problem is that when an error occurs, it is always reported in the first row.

Oops...I left out that one detail. Here's the modified code that sets the CurrentRow property:

public override bool CheckRulesHook(DataSet ds, string tableName)
{
	if (ds.Tables[tableName].Rows.Count > 0)
	{
		this.CurrentRow = 0;
		foreach (DataRow Row in ds.Tables[tableName].Rows)
		{		
			OrdersEntity Entity = new OrdersEntity();
			Entity.SetDataRow(Row);

			// Call validation methods
			this.ValidateCustomerID(Entity.CustomerID);
			this.ValidateShipName(Entity.ShipName);
			this.CurrentRow++;
		}
	}

	// Change this return value to indicate result of rule checking
	return this.ErrorProviderBrokenRuleCount == 0;
}

The CurrentRow property is used by mmBusinessRule to set the error row.
