row color on click

How do I change the background color of a row that has been selected (clicked). I want to set this to a color other than the default dark blue color I'm currently seeing.
Thx

Open grid.css and modify the background-color attribute in the following 2 styles (the second one is the same as the first except for the cells containg links):

.active-selection-true, .active-selection-true .active-row-cell {color:#FFFFFF !important; background-color:#4d8f6d !important}

.active-selection-true a, .active-selection-true a .active-row-cell a {color:highlighttext !important; background-color:#4d8f6d; text-decoration:underline!important }

Open Grid.css and modify the background-color attribute within these 2 styles (the second style is the same as the first... for any hyperlinked data item):

.active-selection-true, .active-selection-true .active-row-cell {color:#FFFFFF !important; background-color:#4d8f6d !important}

.active-selection-true a, .active-selection-true a .active-row-cell a {color:highlighttext !important; background-color:#4d8f6d; text-decoration:underline!important }

Thanks Brian. Worked perfectly!!
