Change grid row color in listpage form

Hi AX guys,

I need to change the  grid row's color if certain conditions are met. The usual solution for this is to override the formdatasource method displayoption(). However, the form is listpage type and  DataSource method can not be overiden. the customization works only in the interaction class (AX 2012).  How can i do this in the interaction class.any idea or any sugestion.
