Thanks for replying.
I have checked and all the properties are set as mentioned.
There is one point in the article you mentioned - "Frozen columns rely on row height synchronization between the frozen and non-frozen parts. Some browsers, such as Internet Explorer 9 and Firefox, require a line-height style set in pixels. Otherwise, the synchronization might not work properly possibly because of sub-pixel quirks." By any chance is this causing the problem.
Creating Sample project may take some time. I will upload once it is done.
Once again thanks for your assitance.
