Mouse.GetPosition Method

The position of the mouse pointer is calculated relative to the specified element with the upper-left corner of element being the point of origin, 0,0.

During drag-and-drop operations, the position of the mouse cannot be reliably determined through GetPosition. This is because control of the mouse (possibly including capture) is held by the originating element of the drag until the drop is completed, with much of the behavior controlled by underlying Win32 calls. Try the following approaches instead:

• Call the GetPosition method of the DragEventArgs that is passed to the drag events (DragEnter, DragOver, DragLeave).

• Call GetCursorPos, using P/Invoke.

The following example shows how to use GetPosition to determine the position of the mouse pointer. The position of the mouse pointer is stored in a Point structure. The X and Y values of the Point object are displayed in a TextBox.

// displayArea is a StackPanel and txtBoxMousePosition is 
// a TextBox used to display the position of the mouse pointer.
Point position = Mouse.GetPosition(displayArea);
txtBoxMousePosition.Text = "X: " + position.X +
    "\n" +
    "Y: " + position.Y;
