Hi,
Thank you for your interest in Syncfusion products.
This can be achieved by using the Cut(), Copy(),Paste() and AddNew() method of GridDataBoundGrid.
this.gridDataBoundGrid1.Model.CutPaste.Cut();
this.gridDataBoundGrid1.Model.CutPaste.Copy();
this.gridDataBoundGrid1.Model.CutPaste.Paste();
this.gridDataBoundGrid1.Binder.AddNew();
Please refer the sample in the link that implements these functionalities in the contextmenu of gridDataBoundGrid:

Kindly try this and let me know if you need further assistance.
