Developing a blazor page

Hello.
I am in the process of developing a blazor page. The page contains a drop down list, a button and a table. I need to select a client from the drop down list to retrieve the data for the client from the Database. But when I press the button, all clients come from the database in the table. I enclose the codes below.
Is there anyone can help me with that?

You are passing the parameter for filtering clients but not using it anywhere.
public class KlientGateway
    {
        ApplicationDbContext _db = new ApplicationDbContext();

        public List GetKontoplan(int KlientId)
        {
            return _db.Kontoplan.Where(x=>x.KlientId==KlientId).ToList();
        }
    }

Filter the list: .Where(t=> t.KlientId == KlientId).FirstOrDefault();
public class KlientGateway
   {
       ApplicationDbContext _db = new ApplicationDbContext();

       public List GetKontoplan(int KlientId)
       {
           return _db.Kontoplan.ToList().Where(t=> t.KlientId == KlientId).FirstOrDefault();
       }
   }
