Datagrid "Focused Grey Box" problem?

Hi Everyone,

I have got 2 grids and they behave like master and detail grids. One grid lists all the order and 2nd one lists all the items for the Order.

All the orders are filled in Top grid and when user click on different orders its items are shown.

Now when user clicks on product on orderitem grid(below) and then clicks on other Order in Top Grid the orderitem grids leaves a focused cell(Grey Box) on the cell clicked.

i have implemented the functionality of colouring the cells from this example

I have temporarliy uploaded the screenshot at following location to get the clear picture.

I am using VS 2003.

I would really appreciate if anyone could help me for direct me in right direction.
