I have created a grid containing several gridcells. Every gridcell displays the "icon_small" image. I would like to achieve the following: When the end-user moves to a given gridcell using the remote control, the selected gridcell displays the "icon_big" image. When the end-user moves to the next gridcell, the previous gridcell displays "icon_small" and the newly selected gridcell displays "icon_big". etc...
So basically what I want is when I focus on one gridcell, the image changes to another. And when I focus on other cells, the image previous will change back and the current image will change.
I know that I can use onFocus function to change image when the gridcell is focused on. But I don't know how to change it back when it focus on other gridcell.
Any advise would be appreciated Many thanks in advance
