Select a line to be grayed in a grid

Hi,

I would like to know a solution to select programmaticaly a line in a Grid definedd in the tml in order to get it grayed.

I want to select this line when one of its attribute contains a specific value or a value is greater than one value,

even when all the values are updated. It is to select this line with this value when the grid is displayed.

Version : Tapestry 5.3.

Thanks by advance.
