Hi DVD,
Thank you for your patience.
Yes. You can add a new row using the same edit template that you are using in the existing rows in your own custom button.
[C#]
protected void Button1_Click(object sender, EventArgs e)
{
this.GridGroupingControl1.TopLevelGroupOptions.ShowAddNewRecordBeforeDetails = true;
Syncfusion.Grouping.Record record = GridGroupingControl1.Table.AddNewRecord;
if (record != null)
{
record.BeginEdit();
}
}
Please refer the sample in the below link which illustrates the above:

Thanks,
