Child updatepanel not updating
As a result, it becomes hard to make changes in your application.
Lable1 present inside the update Panle and Label2 is in the outside of update Panel.
In this regard Microsoft AJAX Web application is never an exception.
You may find your application packed with a plethora of Update Panels and event handlers. NET AJAX offers more than one technique to do one thing but you cannot use them consistently.
Net web developer, but the truth is, I always preferred the MVC than Web Forms.
Especially what I hate in Web Forms is the update panel control.
