how to make control freeze like design time?

[wenight]

1. Can we make the Combo Box not drop down if we click on it even though it have item in the list,
   
2. button not click-able even though it have the on_click event..
   
3. textbox not allow to set focus but not in disable mode...

everything like design time.. because I want to do drag and drop control like visual studio.. but I can drag now, just when I want to click the control to drag, the control still remain the default function...
