LayerList Widget - Turn on Sublayers

denverweston

Is there a way to turn on and off all sublayers within a group within the Layer List Widget when the group is checked or unchecked?

In one version of mine i did add code to TOC.itemrender - in the createchildern function i think.

But in another version I setup a listener on the Show of a layer.  This might work best for you since you want to take action when a layer is checked (made visible).  You can set the listener for just the layers you want.

The code for this is
layerlist.addEventListener(FlexEvent.SHOW, mapLayerAddHandler2, false, 0, true); 
where mapLayerAddHandler2 is your function.

I wanted my procedure to run whenever any layer, except basemaps, were made visible. 

That code looks like this.

for (var j:int = 0; j < layerlist.length; j++)
{
      if (toc.basemapLayers.getItemIndex(layerlist.id) == -1)
    {
  layerlist.addEventListener(FlexEvent.SHOW, mapLayerAddHandler2, false, 0, true);
    }
}

Hope that helps.
