I have a editable nested repeater containing the data.I use it for showing the data and also for saving the data which is updated by the user.
I want to detect particular cell/row for which the data has been modified by the user so that I can update only that particular row in the database instead of saving all the data again.
Is there a way to work this out.Which would be the best technique to use ,JavaScript or server side code ?

HTML

Resource country etc |    Week1 Week2 Week3  | Total
ABC        XYZ             10     15    20      45

This is the repeater structure.
Middle one (Weeks showing hours worked by resource which is editable) is the nested repeater.
Values can only be changed in the nested repeater.
I maintain unique ID's for each resource in the hidden field.

Can you suggest me some ways to achieve this functionality ?

why don't you use the gridview component? You can edit a row and based on the keynames you can update that single row in the database.

The complications does not permit me to use the gridview.Performance is the problem

if performance is this issue use javascript or jQuery

and update with async ado.net. Your website goes on while the data is handled in a different thread.
