I need to change the font from normal to italics when a user changes the set of values.

I am having one form, form this form user can navigate to other form using a button where set of values are displayed in a table with check boxes, by default all the check boxes are selected. User can select or deselect the check boxes. Suppose user deselected one item then I need to change the font for the name in the previous form to italics.

Is that possible to do so? Kindly help me out to solve this issue.
