Regarding Async post using http post.

Question

Dear All,

I am Beginner in ASP .net MVC and Angular 5. What I want to do is that I need to insert data into master and details tables.

What I am doing is reading values from bootstrap table contains form using Angular 5 and if I found any value then I am inserting that record(using loop both inner and outer for loops).

My problem is that it is giving me exception as "Fatal error encountered during command execution."

My question is that whether I should go with Async post.

If yes then please tell me how to do that without using "Entity Frmaework".

If No then tell how can I overcome above problem.

Thanking You in advance.
