Hi 0L,
The DockingClientPanel is intended to serve as a container for the non-dockable controls on non-MDIcontainer forms.It will resize automatically according to the state of the docked controls in the form.
For more details, please refer
this knowledge base article and our documentation about the class DockingClientPanel, which is available online
here
Please let me know, if you need more assistance.
Thanks for choosing Syncfusion products.
Regards,
Joy
