GridView unbound checkbox state

[David C]

I have a GridView that is bound to a datasource but one column has an
unbound checkbox to use for selections for emailing. The GridView also has
paging set to 10 rows per page and the datasource table has approx. 400
records that I want to randomly select. I have everything working ok,
except that when I hit the next page link I lose all the checked values. Is
there any way to retain them between postbacks? I though of adding a column
to the database table but then I would have to "Edit" each row that I want
to check. Any help or direction would be greatly appreciated.

You will be required to play with session in order to keep changes between
page navigation. For example, you can keep datatable in session which you
are using for binding here. And then you can update gridview values in
session datatable before navigation to other page.

That seems like a lot of work. So every time they click on a new page number
I have to check to see if the 10 records I am about to display are already
selected?
