remove only InfoSymbol and red x mark

MikeJun

I downloaded identify features and zoom to query result sample code and put it together.
Sample code simply gets rid of all graphics however I'd like to remove only infosymbol and red mark that pops out after clicking identify tool.


   private function mapClickHandler(event:MapMouseEvent):void
   {
    //clickGraphicsLayer.clear();
    //var clickGraphic:Graphic = new Graphic(clickGraphic.symbol);
    clickGraphicsLayer.remove(clickGraphic); I put this but won't work.

please help

I am not sure if I understand the question, but in that example your graphics layer is bound to the lastIdentifyResultGraphic

<esri:GraphicsLayer graphicProvider="{lastIdentifyResultGraphic}"/>

If you want to keep the graphic and add to it just rename the Graphics layer and add the lastResultGraphic to it.

<esri:GraphicsLayer id="resultGraphicsLayer"/>

Inside the myResultFunction:

lastIdentifyResultGraphic = resultGraphic;
resultGraphicsLayer.add(lastIdentifyResultGraphic);

Please let me know if you have any questions.
