I am trying to setup event in the server side, so when request coming, i register an event, and from other places i can subscribe to this event, say certain properties change, i want to raise or execute the event. Is it something possible in asp.net (c#)?  So similar to what JS has, publish an event, and subscribe from diff places.

Yes you can.

Essentially you can create a class that inherits from a standard control.  

public class MyUserControl : UserControl
{
   //this allows you to "publish" the event
    public delegate void onMyEvent(int AParam);
    public event onMyEvent MyEvent;
 
    public MyUserControl()
    {
          //subscribe to the event
          MyEvent += MyEventHandler;
    }

   // this occurs when the event happens
    public void MyEventHandler(int Param)
    {
                // do something
    }

}
