Controls.AddAt appears to be replacing controls

[Guest]

The problem is when I add a control using Controls.AddAt(index, control). On
the first page postback it appear to work fine but after the first postback
the last control in the naming container appears to be replaced with the
control that I'm adding in addition to adding the control at the given index.
After each additional postback a further control gets replaced until the
viewstate becomes corrupt and the page errors. If I add the control with
Controls.Add(control) I don't get this problem after multiple postbacks but
the control isn't added where I need it to be.

I'm adding the control from the Validate function from the IValidator
interface from an object that is added to the page's validators collection in
the page's onload event.

Hi,

Posting some code or creating a repro project will make it much easier to
work with such issue.

Without code, my guess is that you're not assigning ID to the control
you're adding to the Controls collection. Without specifically designating
the ID of the control, the Control's ID will be generated using the index.
Since you're adding controls using some fixed position, it may confuse the
runtime that's loading/saving viewstates. If I've misunderstood anything,
please feel free to post here.
