hi Ranjitha

thank you for your reply

the sample code throws "InvalidOperationException: Document state is not allowed"
so i set UseDocumentContainer="True" in the DockingManager
i run it and get "ArgumentOutOfRangeException: Specified argument was out of the range of valid values.
Parameter name: index"
