How to make a drag and drop operation with custom destination location

To let the mouse button release on another region, you can replace the call to MouseDragAndDropOn with a version adjusted to your need.
The function MouseDragAndDropOn is just a shortcut to compile a MotionParam, you don’t need it to model a drag and drop operation.
So let’s look at the definition of MouseDragAndDropOn:
I found it at

github.com

Arcitectus/Sanderling/blob/3e04af29eeacd1bd32ab69cb11adca8ef911c204/src/Sanderling/Sanderling/Motor/MotionParamExtension.cs#L35-L43


      
          		static public MotionParam MouseDragAndDropOn(
          			this IUIElement elementToDrag,
          			IUIElement destination,
          			MouseButtonIdEnum mouseButton) =>
          			new MotionParam
          			{
          				MouseListWaypoint = new[] { elementToDrag, destination }.Select(uIElement => new MotionParamMouseRegion() { UIElement = uIElement })?.ToArray(),
          				MouseButton = new[] { mouseButton },
          			};

That code creates a list of two MotionParamMouseRegion, to model the path for the mouse.

To replace the destination region, create your own MotionParamMouseRegion (Sanderling/src/Sanderling/Sanderling/Motor/Motion.cs at 3e04af29eeacd1bd32ab69cb11adca8ef911c204 · Arcitectus/Sanderling · GitHub) and set its property RegionReplacement to specify the region to move the mouse to.
