Mark -

I am showing my report in the container control.
When I change data and run report again data is not changed in report preview. How can I refresh the preview container?

Without more information I don't know what your problem might be. If you are doing a custom report preview UI then its a little tricky but once you get the hang of it, it's fine.

Have you read my article on building a custom report preview? If you work through that example perhaps you can see what you need to do in your own code.
