Copy Paste In TVG fro one grid to another

Hello Everyone,

I have one requirement in Tree Grid View with copy paste functionality:

Create two TVG, One grid with Copy context Menu and another with Paste context menu.

So if i copy row from one grid and paste into another that should add into cache just below the selected row and should load all child data of copied row.

Achieved : 

• Could able to copy the row from 1st grid but not child data of that row.
• Able to paste into 2nd grid but by default it will paste at the bottom of selected row without child data.

Can you please help me
