This class is used by the DataGrid.HitTest() method to determine where a particular point is with respect to the grid. You can get the DataGrid.HitTestType from the Type property, as well as the index of the Column and Row that were hit.

The static Nowhere property returns an instance that represents a point entirely outside the grid.
