Disable Navigation In Datagrid by Arrow Keys

[seeMohsin]

Hi All,
I am using datagrid control in my window application. I am designing the grid by a table and table style to add extra controls in the cells like button and drop down.
Now, I have everything ok, But it want to disable the navigation in the datagrid cells by arrow keys. I dont want to change the cell by the arrows key as the Tab key does.
Is there anybody to help me out.
Thnx in advance.
Mos
