User Control bug in ASP.NET 2.0?

I currently have a project in production running under ASP.NET 1.1. The
project contains a page that loads a User Control dynamically in the
Page_Load event and then adds the User Control to a placeholder controls
collection. The User Control contains several hyperlink buttons with
corresponding event handlers that perform particular functions within the
control. In some cases the control is specifically removed from the
placeholder controls collection, then re-added later in the code. After the
add, remove, add occurrs in ASP.NET 1.1, the user control's hyperlink buttons
work fine, however in ASP.NET 2.0 the user control's events are not fired at
all for any of the hyperlink (or any button on the user control).

To summarize, the event handler in the user control will not fire properly
under ASP.NET 2.0 with the following code in the Page_Load:

formsControl = Page.LoadContro l(controlVirtua lPath)
InnerFormContro lPlaceholder.Co ntrols.Add(form sControl)
InnerFormContro lPlaceholder.Co ntrols.Remove(f ormsControl)
InnerFormContro lPlaceholder.Co ntrols.Add(form sControl)

Note: The code above is not the actual code in the project (no one would
actually do this), however the code above should still technically work (The
event handlers in the user control fire correctly in ASP.NET 1.1, but not in
ASP.NET 2.0).

Is this a potential bug or has something changed in the underlying
infrastructure of ASP.NET 2.0 that I should be aware of?

Assume that a user control (MyUC.ascx) encapsulates 2 TextBoxes with the IDs 'txt1' & 'txt2' respectively.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
