Basic Accounting application

Question

I want an accounting voucher-like web page in MVC, for that, I'll need a grid with two dropdowns.

 

First will be Cr or Dr, on bases of which it will fill the second dropdown (called ACC) from database in the same row. Now when ACC is selected it will return an ACC_code (its just ID of the data) in a hidden field.

 

On exiting, the grid will save data in a single table.
