Just assign different colors to odd/even rows with CSS -
.aw-alternate-even {background: #fff;}
.aw-alternate-odd {background: #eee;}
It is possible combining column and row colors -
#myGrid .aw-alternate-even {background: #fff;}
#myGrid .aw-alternate-odd {background: #eee;}
#myGrid .aw-alternate-even .aw-column-1 {background: #eee;}
#myGrid .aw-alternate-odd .aw-column-1 {background: #ddd;}
You can also change how 'odd'/'even' values are calculated, for example, coloring rows in groups of 3 (triplets) -
function triplets(){
return this.getRowProperty("position") % 6 < 3 ? "even" : "odd";
}
obj.getRowTemplate().setClass("alternate", triplets);
