TOC check/uncheck box

MayJeff — Mon, 15 Sep 2014 14:39:24 GMT

I download TOC from this site:

http://www.arcgis.com/home/item.html?id=9b6280a6bfb0430f8d1ebc969276b109 .

When FeatureLayer 1 off, I want to turn on sublayer 3; otherwise set it back to default setting. Here is JSFiddle:Edit fiddle - JSFiddle but all the check box for sublayers not able to check or uncheck anymore. Layers show up correctly. Is there possible to perform this task? Thanks.

Your issue is that any click in the TOC is handled by the 'toc-node-checked' event. In your event, regardless of what layer you click on (whether it's a root layer or sublayer), you're always setting the visibility of dynaLayer1. You have to determine if the user is clicking on the featLayer1 layer, then set the visibility of dynaLayer1.

//try to set layer visibility based on feature layer on/off -------------
if (evt.rootLayer == featLayer1) {
  if (featLayer1.visible == false) {
    dynaLayer1.setVisibleLayers([3]);
  }
  else {
    dynaLayer1.setVisibleLayers([2, 5, 8, 11]);
  }
}

I've updated your Fiddle.
