Auto generated sequence numbers

Hello Jascha,
It's best to define a special field/property which can be seen and used by the users of your application to identify business objects (documents). You will need to use the Session.FindObject method to obtain an object by a user-friendly ID. To optimize searching for objects, declare the ID field with the Indexed attribute. Here is some sample code:

C#
using DevExpress.Xpo;  

//  Object with a user-friendly ID  
public class Client : XPObject {  
    [Indexed(Unique=true)]  
    public string ClientID;  
    ...  
}  


// Add object  
Client client = new Client();  
client.ClientID = "A007";  
client.Save();  


// Get object  
Client GetClientById(string clientID) {  
    return Session.DefaultSession.FindObject(typeof(Client),  
        new BinaryOperator("ClientID", clientID)) as Client;  
}  

Client client = GetClientById("A007");  
Console.WriteLine(client == null ? "Client not found" : client.ClientID);  

Please note that you will need to develop your own algorithm for generating unique values for user-friendly IDs. The attached project shows our solution to this task. Hopefully, it will come in handy.
Thank you,

Hi Guys,
Please check the following issue in the Support Center: ID Q130688 (CQ22273 - ( Auto generated sequence numbers ) - how does this work?) in case of any questions on how to use helper classes from this example.
