Here is my code i use to add the graphic.

var graphic = new esri.Graphic(geometry, symbol);

select how? onClick? onMouseOver?

have you seen this sample? it demonstrates how to define a new symbol and pass an existing graphic to display in the map (on top of the existing graphics layer created from QueryTask results)

var highlightSymbol = new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255,0,0]), 3), new dojo.Color([125,125,125,0.35]));
...
dojo.connect(countiesGraphicsLayer, "onMouseOver", function(evt) {
            map.graphics.clear();  //use the maps graphics layer as the highlight layer
            //pass the event graphic geometry and second symbol
            var highlightGraphic = new esri.Graphic(evt.graphic.geometry,highlightSymbol);
            map.graphics.add(highlightGraphic);
          });

I am actually wanting to select it from a list. On the right side of my screen i have a list of the items and will select one and i want it to highlight the associated graphic. Ideas?

well... selecting a graphic and selecting something associated with a graphic aren't exactly the same thing. 🙂

do you have a simplified code sample pointing at public services you can share?
