Dynamic Template control and value persistence

Question

Hi friends
I have created a gridview using ITemplate to generate textboxes in cells and to display the data. The grid is bound using a datatable in PreRender event.
On Page refresh the modified value gets replaced by the existing value from datatable. If I do not bind the gridview in each refresh, the textboxes  gets vanish from the gridview.
Can any one help me to overcome this problem.
Does viewstate will have any role in this?
Thanks in advance

Use Linq to datatable, refer sample.

DataTable dtMain = new DataTable();
DataTable dt1 = new DataTable();
//bind datatable

var rows1_10 = from item in dt1.AsEnumerable()
     select item;
var top1_10 = rows1_10.Take(10);

//do a for-loop and insert into dtMain

DataTable dt2 = new DataTable();
//bind datatable
var rows2_10 = from item in dt2.AsEnumerable()
     select item;
var top2_10 = rows2_10.Take(10);

//do a for-loop and insert into dtMain

Hi Purna,
Try to create  two temp datasets with a datatable containing 10 rows. and bind these two dataset to gridviews seperately.
