I prepared a sample project based on your code but I am not sure what exactly is the described problem - I could not see anything unexpected and I am also not quite sure what exactly you mean by "When I use a datapicker in the main content pane and the top pane (navigation) is collapsed, the images for the datepickers stay in place. They do not move up with the main content once the pane is resized.
In order to be able to attach files, you should open a new support ticket because you cannot attach files in forum threads.
Would you please open a new support ticket, rework the attached sample in order to reproduce the problem and it send it back to me along with a detailed explanation of the reproduction steps and some screenshots? Once I receive it, I will do my best to help you resolve the issue.
