ASP.NET 2010 file format problem

Question

I am asking this question since I am sharing a C# asp.net 2010 solution file with a contract shop. The contract shop in another town has the main control of the solution file. Basically I am working with an older version of the solution file and adding my own web pages to it. When I have completed developing my web pages, I can going to add my code to the general solution file.
Since I am new to working with C# aspx source view and designer files, I am concerned about losing the formatting I setup in my code when adding my new aspx and aspx.cx files to the general solution. Basically right now I am attemtping to line up the tags in the aspx file so I can tell what labels match each other.
Thus will I have a formating problem to be concerned with? If so, is there a way I can prevent from losing the formatting?
