PopupButton: Popup/ContextMenu placement

Hi Markus,

We just set the menu's PlacementTarget = popupButton and the Placement = Bottom.  You could probably set properties like PlacementRect or CustomPopupPlacementCallback on your ContextMenu though to see if those help.

Ahh, I did not even think to look at the content... but if I use PopContent instead of a ContextMenu? Who then controls the placement? (And non of the Placement enum values seem to target the scenario "align right edges")

Hi Markus,

For popups, I believe PlacementTarget and Placement are still explicitly set.  But you have access to PopupHorizontalOffset and PopupVerticalOffset properties you can set on the PopupButton itself to adjust things.

For the PopupContextMenu I solved it by first doing the totally opposite -- setting ContextMenu.Placement=Left (by Loaded-event because XAML definition gets nuked=overridden at runtime) -- and then relative-self-bind PopupHorizontalOffset and PopupVerticalOffset to the ActualWidth/-Height of the according PopupButton.
