Hi Sreekesh,
Thank you for interest in Syncfusion Products.
You can use the tabBarSplitterControl1.TabBarPages.Insert()method to insert the tabpages in specified position/index in a tabBarSplittercontrol.
Here is a code snippet that shows you “How to insert the tabpage in a tabbarSplitter control”.
[C#]
tabBarSplitterControl1.TabBarPages.Insert(int index, tabpage value);
Example:
tabBarSplitterControl1.TabBarPages.Insert(0,tab4);
I have attached the sample for your reference. You can download the sample from the following page.

Please let me know if you have any queries.
Regards,
Hema
