Screen coordinates of a control on a design surface

[MillerMark]

How can I find the screen coordinates of a selected control on a XAML design surface?

Hi @MillerMark

You should be able to get the ViewItem from the selected ModelItem.View and from there use the SelectionFrameBounds and PointToScreen to get the screen coordinates.

I hope this helps.

PointToScreen seems to return points relative to the ViewItem's immediate parent (IOW, no change to the point), so I'm still looking for a way to translate the points derived from SelectionFrameBounds into screen coordinates.

Could be a bug in the designer's extensibility layer. Looping in @chabiss whose team owns the designer.

Any new suggestions on how I can determine screen coordinates?

Update - I've found a hack using reflection to calculate screen coordinates of a control on a XAML design surface. Let me know if there's a more officially-sanctioned way to do this.
