Themes

Question

Hello all

I am using one theme folder for my site.In theme folder i had two more folders one css containing multiple styles another  admin containing one style file. The css theme is used for front end and admin theme for backend.In my database i call css folder.The master pages which i use for admin section i set theme property to false so that it will not take theme from databse(css theme used for front end).I place link of admin theme there.But when i try to access my admin section everything is disabled textboxs buttons etc.

Can anyone help me to make the front end theme cancelled discarded from backend so that i can use my backend with ease.
