WebGrid in MVC is not Refreshing when Page Changes.

Question

I created a WebGrid in MVC, It is Populating 20 Pages with 10 rows each page,I have Created 2 Drop downs

1. depending on the Person who the Server is Assigned to and

2. The Server Name itself.

 

when i Select the Person Name, I should be able to see only his/her Records, the 1st Page seems fine but when i click Page 2, it is not Refreshing All the Records are visible.

 

Please help.

 

Thanks,

Megna.
