Transparent TextArea in TreeGrid


I am using TreeGrid and column type is txt. When I enter edit mode on a textarea, the size of the editor box is good, but the textarea box is transparent. Because of that, the elements in the background can be seen in the textarea box. How can I make the textarea box not transparent?

Thanks in advance,
