display content in alphabetical order sections

display content in alphabetical order sections

I have a stored procedure that returns information and orders it by the
status and then the name of users. Currently when the results are
displayed they are ordered and displayed by the rank and then by name of
the user. I want to display the information as it is but within sections
so like:
A
list all users that start with letter A
B
list all users that start with letter B
How can i go about doing that in app. I am using MVC web app, c# and
knockout.js
Do i go about that in the View or View + knockout.js or controller?
