thanks for quick response but my question is 

If i have total 10 records in my grid and i need to add one row  at 7th position. we are updating & adding & deleting records using ui.iggridupdating

we do not want to refresh whole grid using data source, we need to add only that row which is new in data source. for that , we need to add that row of particular row location of data source.

ex. if we have total 10 record in grid , we bind new data from server with 11 record and the new record added 7th position in data source so that row should be add on 7 th position currently it will add into last location of grid using $("#Gridid").igGridUpdating("addRow", rowObj);   

please help us.
