Design

Hi Experts
I have a scenario where i have to design a grid view

I will be given a text  file with some Data.
Here is the sample Data
Coverage^1^2^3^4^5^
Coverage^1^a^b^c^d^
Coverage^1^h^g^f^e^
Coverage^1^i^j^k^l^
Coverage^1^p^o^n^m^
Coverage^1^q^r^s^t^

So i will have to check for the number of '1's present in the data and design a grid with that number of rows
Each row will contain three empty textboxes and where the user can enter the data in the textboxes

So when the user navigates from the page i am saving the data in the form of an xml and then populating the same when the user enters the same page.(Question here is how do i perform the same for the grid)

On the page load function i can get the number of rows and initially they were the empty text boxes there is no issue .But when the user visits the same page again i need to get the data that has been entered into the grid and populate the same in the grid.

Any ideas????
