Problem LayerDrawingOptions for several layers.

mk2 — Thu, 31 Jul 2014 10:08:23 GMT

Hello everyone, I have problems when trying to change dynamically my layers' visual representation.

I have 2 ArcGISDynamicMapServiceLayers, one use SimpleRenderer, another UniqueValueRenderer.

The property layer.layerDrawingOptions is null when my layers are shown initially.

I manage to change style of each layer, but .... When I modify me second layer's representation I see 2 modified layers on the screen firstly, but when

I change zoom level, only the last modified layer is keepenig it's new style. What is going on? What I'm doing wrong?

I change layers' DrawingOptions like this:

if (l as ArcGISDynamicMapServiceLayer)

{

//--SimpleRenderer

if(rndr as SimpleRenderer)

{

srenderer.symbol = symbol;

l.layerDrawingOptions = DrawingOptions1;

//--UniqueValueRenderer

} else if (rndr as UniqueValueRenderer) {

uvr_field = rndr.field;

uvr_delimiter = rndr.fieldDelimiter;

arrRndrInfos = [my new style for sublayers];

dLayer.layerDrawingOptions = DrawingOptions2;

}

<fx:Declarations>

<fx:Array id="DrawingOptions1">

<esri:LayerDrawingOptions layerId="{layerId}" alpha="1" >

<esri:SimpleRenderer id="srenderer" />

</esri:LayerDrawingOptions>

</fx:Array>

<fx:Array id="DrawingOptions2">

<esri:LayerDrawingOptions layerId="{layerId}" >

<esri:UniqueValueRenderer field="{uvr_field}" fieldDelimiter="{uvr_delimiter}" infos="{arrRndrInfos}"/>

</esri:LayerDrawingOptions>

</fx:Array>

</fx:Declarations>
