Hi all,

I currently have webapp that deal with a registration process.
I have an interface called User which has the methods to get Values from the implemented userimpl class as well as methods to add and load the user

i.e.

interface IUser 
{
        bool save();
        string getLastName();
        string getFirstName();
        ....
}

public class UserImpl : IUser
{
      private string lastName;
      private string firstName;
      public UserImpl(string inLastName, string inFirstName)
      {
           setFirstName(inFirstName);
           setLastName(inLastName);
      }
      
      public bool save()
      {
           return DataLayer.InsertUser("sp_InsertUser",lastName, firstName);
      }
}

Now i have the main form which allows the user to input all the registration fields.
Once they hit submit i create a class from the given parameters (along with some validation) and then save the object to the database.

What i would like to do instead is redirect the user to a preview page which will display all of the fields they input and then allow them to hit submit which will do the database insert.

As of right now i figured i would still create the object on the first page and store the details in a session and then retrieve it on the second preview page and continue on from there.
Is this an ideal way to go about doing this?
What would be a better oop approach to this?

Thanks in advance
