How to change Created By column's display format?

Question

I want to change the display format of Created By column in SharePoint 2010. It is right now displaying username like LastName, FirstName.

I want to change it's display format to FirstName LastName.

I want it to whole SharePoint site collection or web application if possible.

Note:- I do not want to use code for that.

Answer 1

Finally I got it using calculated column.

I have created one Single Line of text column named with User & make its value as calculated value to =Me. By that i get a user name like corp\Hardik.Patel (domain\username) in single line of text. after that i had made it hidden so it will not be shown into UI (add new form / edit form).

After that i have created one calculated column with having calculation like below

=PROPER(REPLACE((RIGHT(User,LEN(User)-INT(FIND("\",User)))),FIND(".",(RIGHT(User,LEN(User)-INT(FIND("\",User))))),1," "))

After doing all this, I am able to get the desire output in my calculated column as Hardik Patel.

Thanks for efforts. I really appreciated that. :)
