Hi Vinodh Kumar,
Thank you for writing.
Actually, we do not use RadDock in the main frame of our Examples application. Instead, we are using a special component developed for the purposes of our examples called QsfSplitter. This component and the titlebar with the images are available in the QuickStart project of our Source Code which you, as a customer, can download from your account.
You can also find the QuickStart project attached to the response of my colleague Vassil in at the bottom of this thread
If there is anything else I can assist you with, do not hesitate to contact me.
