Hi Kishor,
1) Changing the shape of the TabPanel.
I am afraid that I am not able to understand your requirement clearly. Could you please let me know whether you want to change the shape of the tabstrip in which the tabs are displayed?
2) Drawing owner drawn tabs.
I have attached a sample that shows how to draw owner drawn tabs. Please have a look at it and let me know if this meets your requirement.
We appreciate your interest in Syncfusion products
