Hi,
Currently the DisallowFloating property of the docking manager can only be applied to all the controls in the docking manager. I have created a
feature request with the development team to add a new method , something like SetDisallowFloating(Control cont) that would disable the specified control from floating but would still allow docking.
We will try to implement this feature as soon as possible.
Thanks for using Syncfusion Products.
Regards,
Vijay
