Removing Graphics from Layer

[SimChin_Siang]

Hi folks,

I encountered problems removing Graphic from GraphicsLayer.

My code is as below,

if(themesArray.removeItem(tName))
{
   check = true;
}
else
{
  themesArray.addItem(tName);
}
         
for(var i:int=1; i < response.SrchResults.length; i++)
{
  var theme:Object = response.SrchResults;
    
  var str:String = theme.XY;
  var subStrIndex:int;
  var x:String;
  var y:String;
    
  subStrIndex = str.search(",");
         

x = str.substr(0, subStrIndex);
y = str.substr(subStrIndex + 1);
     
var mp:MapPoint = new MapPoint(parseFloat(x), parseFloat(y), new SpatialReference(102100));
     
var myGraphicMarker:Graphic = new Graphic(mp,
new PictureMarkerSymbol("http://www.onemap.sg/icons/"+ tName + "/" + theme.ICON_NAME, 25, 25));
    
myGraphicMarker.toolTip = theme.NAME;
if(check == true)
{      
  gLayer.remove(myGraphicMarker);
}
else
{
  gLayer.add(myGraphicMarker);
}
}
}

What i want to do is to remove graphics that is already on the map if previously had already added.
For example first time i selected something new, it will be added to the array and it will created new graphic to add to the Layer.

But if the graphics has been added previously, i want to remove it from the map instead.

Seems like gLayer.remove(myGraphicMarker); doesn't work.

Any experts can render some help?

Thanks in advanced!

gLayer.remove(myGraphicMarker) requires the passed in Graphic to be the same instance as a Graphic already inside the GraphicsLayer otherwise it doesn't know which one to remove. It looks like you're creating a new instance which won't work. You could instead loop through the graphicsProvider to find the instance you want to remove and then pass that to gLayer.remove().

Thank you Dasa Paddock for the help.
