Hello Satish,
One problem I see in your code is that you did not specify width and height of  InlineUIContainer - in its constructor or trough Width and Height properties, so you can try do this at first place. If this do not help, please send us sample project that reproduces the problem so we could be more useful.

Kind regards,
