how to use web grid and Form control in save view in MVC 5?

Question

In my sample, i couldn't use web grid and modal page in same view.

 

The  problem is , now i giving a header model with ienumerable and now  if i use web grid , the  modal page text box controls not working , it making compiling error.  if i give a  header without ienumerable , The web grid not working.

I expect peace full solution . "I need to have web grid and other form controls in same page."
