Is it possible to get or set a note's popup location on the screen? I'd like to put it off to the side by default so that it doesn't cover up my note symbol(s).
I think the answer is no. The SDK help for Popup.SetTarget states the following:
[INDENT]Popup windows have the ability to be linked to a target location on the map. If a popup window is visible, and the target location is within the currently visible extent of the map display, a leader line will be drawn from the popup window to the target. You cannot set the target for MapItem popups (such as Popup) as the target is dictated by MapItem properties. The target location can only be set for temporary popups i.e. popup windows that have been explicitly constructed. [/INDENT]
So for Notes you cannot control the location of the Popup using this property. For graphics with an associated Popup this would be possible. Additionally I cannot find anything to control the default offset of the leader line for the popup.
