TOC Widget - how to default open all layers so that legend shows

GeorgiannaStrode — Wed, 14 Mar 2012 18:53:28 GMT

With the TOCWidget, I'd like for EVERYTHING to be open when the widget opens (the equivalent of clicking 'Expand All').

I already have:
<expanded>true</expanded>
in the TOCWidget.xml and this works to open the mapservice to show the individual layers. But I'd like to have the individual layers open so that the legends show.

Is there a way to do this?

Thanks!

Georgianna,

Sure it is a pretty easy code change in the TOC.as
Add this new function:

        private function expandAll(item:TocItem):void         {             item.collapsed = false;             expandChildrenOf(item, true);             if(item.isGroupLayer()){                 for each (var item2:TocItem in item.children){                     expandAll(item2);                 }             }         }

Search for this line in the the TOC.as and comment it out and add this new line:

                //if(_expanded) expandItem(tocItem, true, true, false, null);                 if(_expanded) expandAll(tocItem);

That's it.

Don't forget to click the Mark as answer check and to click the top arrow (promote) as shown below:
