Its working but causing the whole webpage to flicker, that has made m开发者_运维问答y approach ugly.. Please any programmer help me.. Thanks in advance

Can you post the related code segments? Without that, it is difficult to guess what the problem is.

Page flicker could be:

• Page load firing twice in update

• Timer firing when not intended

  The list goes on...

If you are unable to post the code, I would troubleshoot by removing everything but the core functionality until you can get the flicker to stop then add pieces back in. That is really all I can offer you without the code.
