RE: Adding Controls to a Page 2005-02-23 - By Tim Clamp
Make sure to give your controls an id before adding them to the page and
insure that your controls are added in the same order each time.
Cheers,

We'll here's what I've decided to do.
I load the controls on the page (in the Page_Init() method) and add a
text box that contains the number of check boxes I am dynamically adding
to the page. On the post back I loop from 1 to textbox.value and check
to see if the Request["cbname" + x] is null. I can't think of anything
else and this seems to fix the problem.

Duane, you're best to start with the simple controls on your page and
ensure
that their state is persisted, then add your code and other controls
incrementally until you find out what's causing the state to be lost.
Are
you able to take this approach?
Cheers

I added code to enable view state enabled - no difference. Would it help
if I posted the entire aspx and cs files?

Duane, do you have EnableViewState=true for your asp:textbox and other
controls?
Cheers

That's the thing - I'm not setting any values.
I am using checkboxes, which are not maintaining state and text boxes
which are not saving data that is entered.

Only set the e.g. the Text property on the initial load, NOT on the
postback;
if (!IsPostBack)
{
someControl.Text = "Some Text";
}

I added the code to create the controls dynamically to the Page_Load()
method post back, and in the OnInit() method, but in both cases the data
is not being preserved.
What am I doing wrong?

You have to re-add the controls on postback. The data is then
repopulated to the controls and you can access the data.
