Get the mouse position during drag and drop
Never mind, I've found a solution. Using DragEventArgs.GetPosition() returns the correct position.
DragOver handler is a solution for general situations. But if you need the exact cursor point while the cursor is not in droppable surfaces, you can use the GetCurrentCursorPosition method below. I refered Jignesh Beladiya's post.
using System;using System.Runtime.InteropServices;using System.Windows;using System.Windows.Media;public static class CursorHelper{ [StructLayout(LayoutKind.Sequential)] struct Win32Point { public Int32 X; public Int32 Y; }; [DllImport("user32.dll")] [return: MarshalAs(UnmanagedType.Bool)] static extern bool GetCursorPos(ref Win32Point pt); public static Point GetCurrentCursorPosition(Visual relativeTo) { Win32Point w32Mouse = new Win32Point(); GetCursorPos(ref w32Mouse); return relativeTo.PointFromScreen(new Point(w32Mouse.X, w32Mouse.Y)); }}
