I have some code written that makes a calendar visible when i click on a certain combo box (basically a pop up calendar control). For efficiency's sake, I put a list box on top of the calendar element. When the code unhides the calendar however, the list box obscures it. I've tried the bring to front/send to back options but they haven't worked. I also tried creating another calendar control to see if the order in which i created the elements made a difference. How should I fix this?
