For those with a similar question, here is a working solution. I could not get the unique renderer to work on the selection set. Instead, assigned a graphic (and unique color) to each feature. There should be a better way to do this, am open to any suggestions.-Raghufunction colorSelFeatures(featureset)
{
for (var i = 0; i < featureset.length; i++)
{
//add each feature from featureset to graphic
var graphic = features;
graphic.setSymbol(new esri.symbol.SimpleFillSymbol().setColor(getRandomColor())); //calls a function to assign color to each graphic
map.graphics.add(graphic);
}
}
