Symbology from FeatureLayer

BrunoPereira1

Hi,

I got this problem, I have a FeatureLayer from Url

var featureLayer:FeatureLayer = new FeatureLayer(url);

But, the property Renderer (about symbology) in the FeatureLayer is null, and I want to change the the symbology properties.
I got a Polygon with the property Style "solid" and I want to change and set to "backwarddiagonal".

Thanks.
Bruno

Robert, Thanks for Help!

Bruno,

You can get the renderer from the drawingInfo. Make sure that the layer is loaded first though by calling this line after the featureLayer.load event
featLay.layerDetails.drawingInfo.renderer

Robert,

I've tryed that, but the symbol is null, like the FeatureLayer...
When I add that FeatureLayer on myMap the color and everything is the same way on the Mapserver, I just need to add with a different style.

I look Inside the FeatureLayer I can see on debug mode the property FeatureLayer > Extent > DefaultSymbol and there I have the style, but I don't have access, I can't set that property!
I can't get properties of the symbol from the FeatureLayer!

😞

Thanks!

Bruno,

Since the renderer is null I guess you would have to get the first feature from the feature layer and then get the symbol from the graphic and get all the way down to the simpleFillSymbol's color property. I don't have any code examples for this.

But how I get color properties?

I can set a new renderer, but I have to keep the original color

Thanks
Bruno

Bruno,

Simply define one in code and assign it to the feature layer.

                            var sr:SimpleRenderer = new SimpleRenderer();
                            var oLine:SimpleLineSymbol = new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID,0xff0000,0.8,1);
                            sr.symbol = new SimpleFillSymbol(SimpleFillSymbol.STYLE_BACKWARD_DIAGONAL,0xff000,0.8,oLine);
                            featureLayer.renderer = sr;
