Hi Kamalakkannan,
Thanks for using Syncfusion products.
Did you try using dockingManager's ControlsArray as shown below?
foreach (Control ctrl in this.dockingManager1.ControlsArray)
{
Console.WriteLine(ctrl.Name);
}
This will show the control name as mentioned (gpParent).
Please refer to the below sample and let me know if you see any problem.
Best Regards,
Mano
