Dont know if this helps, but here: http://carolinasrcoos.org/carolinasrcoos.html is how I handled I think what you are asking about.
The check box turns on the layer, clicking the radio button will enable GetFeatureInfo requests for that layer when you click on an item in that layer.

So I think that I need to register a listener if I check one of my radio button like this one: listeners: { "radiochange": function(node){ // alert(node.layer.name + " is now the the active layer."); node.getattributes(); } I will take a deeper look at the api. Or do you perhaps have a little example? Thanks a lot. best regards Sarah _____ On Mon, Apr 12, 2010 at 10:10 AM, Sarah Schuessler <[email protected]> wrote: > Hi list, > > is there a best practice for choosing a layer: > I have different layer and for one of them I want to get attribute data.
