There are a few issues... -your doSimplify function is never used -you don't need to pass in your polygonGraphic to doQuery since polygonGraphic is global I put together a working example using services hosted by esri: <html>

There's a clustering example in this bundle of demos: http://resources.esri.com/arcgisserver/apis/javascript/arcgis/index.cfm?fa=codeGalleryDetails&scriptId=16092 This one builds on the sample included above: http://www.arcgis.com/home/item.html?id=c546bc8d4f0b4c0fbdf149b92223e681

Link works for me... I took a quick look. Where do you add your dynamic layer to the map? I see where you create it: //load basemap dynamic last so it's always on top
dn_layer = new esri.layers.ArcGISDynamicMapServiceLayer("http://" + mapserv + ".geostor.arkansas.gov/ArcGIS/rest/services/BASEMAP_DYNAMIC/MapServer",{id:"dyn_layer"});
dyn_layer.setOpacity(".5") but I don't see where you add it to your map. Also, I can't get your dynamic layer to display from the services directory but I might be using the wrong URL: http://www.geostor.arkansas.gov/ArcGIS/rest/services/Basemap_Dynamic/MapServer?f=jsapi Finally, and this is just out of curiosity, what is the advantage to using your initLayer function rather than just creating and adding layers to your map?

If I understand you correctly, you should just pass in null. Check out the docs for dojo.declare: http://docs.dojocampus.org/dojo/declare

That code looks fine. I would say your problem is with your map service if nothing displays when you load your page. Are you able to view your service using the JavaScript preview from the services directory? The url should be http://servarcgisprd/arcgis/rest/services/Demo_001/MapServer?f=jsapi

Can you verify that you're setting your query geometry correctly? Double-check that you're handling the result of the buffer properly.

For your second query to run successfully, you'll probably need to configure a proxy. From the sample's page: Notice that this sample references a proxy page in case the geometry of the first block group is so complex that the second query exceeds the maximum 2000 character limit that some browsers impose on GET requests. See Using the proxy page to learn more about this.

Since you're now dealing with points, the simplest/quickest fix would be to use map.centerAt(mapPoint) instead of trying to zoom to an extent. Instead of: map.setExtent(taxLotExtent, true); Try: map.centerAt(selectedTaxLot.geometry);

JavaScript isn't going to be able to talk to your SQL DB directly. You'll need to use something server side to make the connection, run a query and serve out the results.

Yep. You'd also want to modify the onRowClickHandler() function as it expects a polygon and not a point. You could just have the map pan to your city point or you could build an extent from the city point.

Make sure you're passing a valid node ID to the filtering select constructor...if you've got a lot of code, maybe just upload it as an attachment?

I ran into this in the past and got around it by using a filtering select. Same appearance and functionality but you will also be able to get to your "hidden" values. Edit: try it out here: http://archive.dojotoolkit.org/nightly/dojotoolkit/dijit/tests/form/_autoComplete.html?testWidget=dijit.form.FilteringSelect Run this in the firebug console: dijit.byId("setvaluetest").get('value')
dijit.byId("setvaluetest").get('displayedValue')

</html> I didn't change much besides the map service used by the find task. You were on the right track for replacing "TLID" with "FID." Edit: If you're just starting out, go with version 2 of the API: http://help.arcgis.com/en/webapi/javascript/arcgis/
