I have a aspx web page with several hidden(visible=false) panels on it. 
Depending on the task the user is going to perform I show or hide the 
appropriate panel. What I'm discovering is that my controls on the panels are 
not firing their events if the panel was initially hidden when the page 
loaded. 

For instance, i have a panel with a button and a 'onclick' event defined. 
The onclick will only work if the panel is intially visible when the page 
loads but not if the panel was hidden when the page loaded. I also noticed 
this with my drop down list not loading list items either.

Is this behavior by design? If so what should I do to get the events to fire 
after making a panel visible after it was hidden initially? Any help is 
greatly appreciated!!!

John,

Yes, it is by design. Server controls with Visible=false don't render to the
client and, consequentially, don't come back in postbacks.

Leave Visible=true and hide the panels with css rule display:none.
