This error is encountered because of AJAX request conflict. When the RadDocks title-bar is clicked many times the DockPositionChanged event is fired more than once. Because the dock's AutoPostBack property is set to true, a couple of AJAX requests are fired even before any previous AJAX post back has finished. This on the other hand generates a duplicate of the RadDock and throws an exception.
You can overcome this error by adding an AJAX Loading Panel that will ensure the AJAX post back to be finished before a new one is started. For your convenience, I have attached a sample project, that shows this can be done.
Please do not hesitate to contact us, if you have any further questions.

http://www.bbc.co.uk/home/ if you look on this examples you see that you can move dock how you want and work quick and good.
Do you have some Ideas?
Thanks
Here are a couple ideas to improve the performance of an application that has dynamically created RadDocks:
1. Use a hidden UpdatePanel to add the docks to, so that when a certain RadDock is moved, closed, expanded/collapsed only this RadDock is updated. I have attached a sample project that demonstrates this approach.
2. Another idea is, to load the content inside the RadDocks using WebServices. We do not have such example and you should implement your own way of loading dynamic content through WebService.
3. Save the state of the RadDocks using WebServices. This way you do not have to make AJAX postbacks on every action you perform with the RadDock. We do not have an example that demonstrates this approach, and you should implement it yourself.
