Setting Graphic symbol color after graphics layer is drawn on the map

SanthoshKumar3

Hello,

I have a graphics layer drawn on the map with several other layers. I want to set a different color for the symbol based on a condition. So, I have used symbol.SetColor method which does not work.

var layer = map.getLayer('layerid'); layer.graphics[0].symbol.setColor(new dojo.Color("red"));

Any suggestions?

Suggestions:

  1) Best solution is to add a renderer to the layer based on the conditions so you don't have to worry about changing symbol colors directly.

  2) To change the symbol directly, here are the general steps (not tested):

var layer = map.getLayer('layerid'); // get the symbol var symbol = layer.graphics[0].symbol; // change color symbol.setColor(new dojo.Color("red")); // assign symbol back to graphic layer.graphics[0].setSymbol(symbol);
