Hi Mirang,
The Docking control doesn't support overriding of this behavior. We have a feature request for this and you can track its progress and vote for it in PITS. If you give us some more details about your request we will be able to design this feature in order to help you to achieve what you need. Some screen-shots and steps will be of great help.
All the best,
Miroslav Nedyalkov
the Telerik team
