Hi Arun Berlin,
Thanks for
contacting Syncfusion support.
Query#1: No rows
should be selected automatically (Allow only manual selection) && Query#2:
Row selection only by using checkbox click.
To select/deselect
the rows through checkboxes we need to set the selectionSettings.mode as
“Row”. Also, You can achieve your requirement by setting the “selectionSettings.checkboxOnly”
as true.

Query#3: State
persistence of checkbox(s) during the Edit ,Add ,Delete operation.
For Batch editing, we can persist the row selection only on the “Edit” action using the “selectionSettings.persistSelection”
property. We could not persist the selection on and Delete actions.
Please get back to
us if you need further assistance on this.
Regards,
Pavithra S
