DataGrid hilited row color?

[webmaster at curiositi.com]

I'm fairly new to working with LiveCode Data Grid controls.  I've 
noticed that you can set the color for hilited rows.  In my case, I'm 
showing hilited rows with a RED background color.  However, when the 
data grid loses focus (click in a text field or on a different open 
stack), the hilited row loses the red color and goes to a middle gray 
color.

How do I specify the color for hilited rows when the data grid is not 
active?
