Just a shoot in the dark: can you put your grid in a container? Then, you could play with the container's code to hide it when the calendar gets the focus. I think this happens because activex controls use a different hwnd handle.

>I am using a 3rd party grid control called Janus Grid. On the same form I am using a drop down calendar control. When the calendar drops down, it is always behind the Janus Grid. Does anybody know how to get controls to display on top of a Janus Grid?
