Hi alibasha,

Refer below links.

1. Nested GridView in ASP.Net MVC
2. Nested GridView or Repeater Table structure in ASP.Net MVC

Hi,

Thanks for the help. The following link was very helpful to me in doing my task. They have used EF, but I am getting data from WebAPI, I have changed code little bit. For Reference I am adding my code here.
