How to change the colour of grid cells in Dynamics AX

Hi,

I have a scenario in which i want to change the colour of the grid cell whenever i clicked/select that particular cell.The problem is that displayOption method of the datasource is not called when i select that cell.I do not know how to call the DisplayOption method manually.

DisplayOption method takes two arguments.

1. Record

2 FormRowDisplayOption (object)

The problem is that i dont know how to initialize and pass the second argument that is FormRowDisplayOption to the displayOption method.and whether tsome properties needs to be set for the object before passing to the method.

Please give me any solution if any one knw it.

Thnaks.
