C# - Dynamically Populating Column Headers In A Gridview?

I have a vb.net website with a gridview that currently has exam questions displaying vertically in each row like this:

Name question answer
-----------------------
Joe question1 answer1
Joe question2 answer2

[code]....

But I would like to change it, so that each question is a header, like this:

Name question1 question2 question3
----------------------------------
Joe answer1 answer2 answer3
Jill answer1 answer2 answer3

This makes it more readable since each user is only listed once.I would like to stick with a gridview instead of rewriting all my code.I am actually binding my data to the gridview via some other programmers class. I am using LINQ like this:

Return (From entry In report.FetchAllEntries()
Select questionID = entry.Question.QuestionID,
userID = entry.Session.User.ID,

[code]....
