how to capture Esc or Enter key_press event in read-only DataGrid

I am trying to capture a key_press/key_down/key_up (any of them) event in a read-only DataGrid, so that when Esc is pressed I can change the focus to another control or when Enter is pressed I can capture the data in the current cell and give it as a value to another control. So far, the key_press/key_down/key_up events are not being catpured. How can I fix this?
