You could create an event on your Component called something like ‘UpChanged’ and subscribe to the event. When you come to the code that can only run when the component is in the ‘Up’ state you could set a flag that indicates your ‘task’ is waiting for the up state to change. Something like this:

//When you initialize
var e = ...;
e.UpChanged += new EventHandler(Component_UpChanged);
bool waitingForUp = false;

//The code snippet that is waiting for up to be enabled
if (!e.ComponentUp)
     waitingForUp = true;
else 
     DoWorkHere();

//The delegate
void Component_UpChanged(object sender, EventArgs e)
{
     if (e.ComponentUp && waitingForUp)
          DoWorkHere();
     waitingForUp = false;

}
