Hi vinay uthappa,

 Could you please tell us what dll version you're using because I tried the code that you send us and everything was working fine. I've attached the sample project that I used (I've just set a little bit bigger size to the items and update the fluid state on load too) so could you please examine it and see if it helps you?

Best wishes,

Hi vinay uthappa,

Have you tried the sample application attached here? The code snippet you sent is implemented inside a Silverlight UserControl and it works as expected on our side. However, if you manage to reproduce the issue in a small working sample and send it to us, we will definitely further investigate your case.
