Just implement the cursor your self. Create a class named MyGridView that 
inherits GridView. 

In it, create an observer on yourself to catch the KeyPress event, and add two 
class variables (let's name them $X and $Y) to store the cursor coordinates. 

Catch the Data event too to define the background / foreground of the cell: 
Color.SelectededBackground and Color.SelectedForeground for the current cell 
(Row = $Y and Column = $X), nothing otherwise (the standard colors).

Then each time you move the cursor, update the $X and $Y variables, and 
refresh the old current cell and the new one.

If you don't want to use the Data event, you must use the MyGridView[X, Y] 
cell accessor.
