Define the 1st and last grid columns as navigation limits

[ratamaster]

Hi
I have a grid that is navigated with the arrow keys
I need to define the first and the last column as the limits, this means that when I reach through the keys the last column, and then I press right arrow again, I don't want to jump to the first column, and on the other hand, when I reach the first column, I don't want to jump to the last one.

Do you know how could I do this?

Any idea?
