Resume sharing using Asp.net MVC

Question

Details of my project:

Here I am trying to do a resume sharing asp.net MVC website by using MySQL database.Where 2 roles will be present one for Hr and another for Trainee.

Based on the RoleId It will work when Hr will open then particular Trainee details it will get all the details related to the trainee means View Resume.
When trainee will login he/she can insert Qualification details, Update and View resume also.
Requirements:
.Cascading is required on the Registration page.
.In Qualification Details part half the data inserted successfully in the database but half are not inserted.
.Updation and View resume also required.

As I am new to.Net I don't have so much knowledge on MVC. So If anyone can solve these I would be obliged.

Here I attached my project and database.
