I'm using a WPF Popup control to display some data for a custom control. I currently have the ability to resize the popup manually via a Thumb object and the DragDelta event when dragged from the right side of the popup.
However, when I move the thumb over to the LEFT side of the popup and attempt to resize the popup via the same event handler, it goes all wonky ... it seems the e.HorizontalChange value is totally inconsistent when dragged from the left.
Anyone have any ideas? Perhaps a different way to resize a popup from the left?
