Note This articles discusses the ValidationSummary control, however this problem and the hotfix apply to all Validator controls, such as RangeValidator or RequiredFieldValidator.
After you upgrade from the Microsoft .NET Framework 1.0 to the .NET Framework 1.1, the ValidationSummary control may no longer appear in existing ASPX pages that contain that control.
Also, the Page.Validators.Count property has a value of 0, although a ValidationSummary control is on the page.
Note The upgrade process does not cause this problem. This problem occurs in the .NET Framework 1.1.
This problem occurs because Validator controls are not added back to the Page.Validators collection correctly. This behavior might occur when you re-parent (change the parent or the container of) a ValidationSummary control in the control tree. For example, you may experience this problem when you move a ValidationSummary control from the default page collection to a new Forms collection during page Initialization.
This behavior may also occur when you add a UserControl to a page and the UserControl contains a ValidationSummary control.
