How do I display data from multiple tables in a single MVC view

Question

I am having a hard time solving the following with an MVC view.

My goal is to display data from multiple tables in a single MVC view. The bulk of the data comes from

Answer 1

It is simple just do what I say step by step.

1. add connection string into web.config file

2. select models from solution explorer and add 4 classes as following

   • 1st class for first table "i have employ table which have 3 columns

     public class Employ { [Key] public int Emp_id { get; set; } public string Emp_name { get; set; } public string Emp_city { get; set; } }

   • 2nd class for my tempo table

     public class tempo { [Key] public int ID { get; set; } public int Emp_Id { get; set; } public string subject { get; set; } public string hobby { get; set; } }

   Now I create a third class in model folder which contain value that i want from employ table and tempo table

   public class Alladd
   {
       public int ID { get; set; }
       public int Emp_Id { get; set; }
       public string subject { get; set; }
       public string hobby { get; set; }
       public string Emp_name { get; set; }
       public string Emp_city { get; set; }
   }  
   

   and the final class is datacontext class

   public class DataContext:DbContext
   {
       public DataContext() : base("DefaultConn")//connection string
       {
       }
   
       public DbSet Empdata { get; set; }
       public DbSet Tempdata { get; set; }
   }
   

3. now go to the Home controller and add code as below

   public ActionResult file()
   {
       // IList tempi=new List();
   
       IEnumerable model = null;
   
       // model = getVerifydetails(id);
       // return View(objcpModel);
       List verify = new List();
   
       cn.Open();
   
       if (cn.State == ConnectionState.Open)
       {
           string query = "select Employ.Emp_name,Employ.Emp_id,Employ.Emp_city,tempo.hobby,tempo.id,tempo.subject from Employ inner join tempo on Employ.Emp_id=tempo.Emp_id;";//joining two table 
           SqlCommand cmd=new SqlCommand(query,cn);
           SqlDataReader dr = cmd.ExecuteReader();
   
           while (dr.Read())
           {
               verify.Add(new Alladd { Emp_name = dr[0].ToString(), Emp_Id= Convert.ToInt32(dr[1].ToString()), Emp_city = dr[2].ToString(), hobby = dr[3].ToString(),ID = Convert.ToInt32(dr[1].ToString()),subject= dr[4].ToString()});//filling values into Alladd class
           }
   
           cn.Close();
       }
   
       return View(verify);
   }
   

4. now the final step is so simple

   1. go to solution explorer
   2. select views folder and left click on it and select add view
   3. now name it as "file" which we give it into controller
   4. check on create strongly type view
   5. select model class from dropdown-> Alladd
   6. select scaffold templet ->List
   7. hit Add button

Now you're done

Happy coding...
