Problem with Page template

In my project i have created pagetemplete.cs and in that i m creating dynamically table,tr and td’s.This templete is called in each and every form of my project.
Now in my pagetemplete i adjusted tr and td valign=top.

My problem starts here. when i run my project 1st login screen also displayed at top which i dont want . i want to display it in center and for that i have adjusted its tr and td as center. but my pagetemplete.cs works here . If i made changes in pagetemplete than login screen comes perfectly but my other forms not displayed in a correct manner in which i want.

SO can anyone help me to come out from this problem? What should i do without changing in pagetemplete i get correct result?

Thanks in advance.

Plz.. help me..
