Hover in templategrid with nested datagrid

Hi all, I have a templategrid with a nested datagrid. Templategrid has the follwing hover effect: On-hover, background color changes. Background of nested datagrid remains white / default. Target behaviour is: User hovers over templategrid or nested datagrid and the background color of both should change simultaneously. Any suggestions? E.g. Is there a listener in data grid for on-hover? I could not solve it yet...

This can be achieved by using CSS. the datagrid probably has a background color white (#fff), you need to change this for all datagrids on a templategrid something like :

.templategrid  >  .datagrid {
background-color:transparent; /*inherits from parent*/

exact classnames can be found by using firebug or other plugin
