Hi Harshul,
Thanks for contacting Syncfusion Support.
We have checked the reported query “Want to insert Template column in the particular row” from our side. We regret to let you know that you cannot add the template for the particular row. You can only add template column for all the record rows.
But you can add to particular cell in unbound row. You can refer the following user guide docuemantation.
Please let us know if you would require further assistance.
Regards,
Jayaleshwari N.
