I'm trying to extract the text from 20 textboxes in a webform and place the information into my database using entity framework. The project builds fine but I keep getting a null error exception on the quicklistitems.Item = ((TextBox)FindControl("txtListItem" + i)).Text; line during testing. I'm not sure if this is the right track or if there is a better class/method to use for pulling data from web controls with loops. I would appreciate any help anyone may be able to provide.

for (int i = 1; i <= 20; i++)
{
var quicklistitems = new QuickListItem();
quicklistitems.ListID = quicklist.ID;
quicklistitems.Item = ((TextBox)FindControl("txtListItem" + i)).Text;
context.QuickListItems.AddObject(quicklistitems);
}
context.SaveChanges();

Thanks,
FOD

I figured it out, the problem was that I wasn't specifying the client side textbox id so it couldn't find the control. I guess sometimes just posting the question makes you think harder about the answer.
