How to implement hot-track for grid rows during the drag-and-drop operation

This example illustrates how to highlight rows during the drag-and-drop operation.

In this example, we have DependencyProperty at the Window class level that stores a current row handle of a row over which the mouse is.

To obtain a current row handle, we use the DragOver event. Also, it is necessary to define RowStyle and add a trigger that will compare the current row handle with a dependency property value and change the current row's background if necessary.
