I'm remembering there used to be a few samples for changing the styling on the zoom slider for navigating.  Did I just dream this? I swear I've seen several different styles, but maybe those were removed because of the newest API version or because of the web page changes to the new resource pages. (I don't hate them as much as some people seem to, but I still can't always find what I'm looking for.) Specifically I would like to replace the icons on the top and bottom of the slider, which are currently up and down arrows, to be plus and minus icons instead.  I think I can override these symbols with a different style, but I'm not sure which style to change. When looking at this component in Firebug, I see a style of .tundra .dijitSliderDecrementIconH, .tundra .dijitSliderDecrementIconV, .tundra .dijitSliderIncrementIconH, .tundra .dijitSliderIncrementIconV {     background-image: url("images/spriteRoundedIconsSmall.png");     background-repeat: no-repeat;     cursor: pointer;     height: 14px;     width: 14px; } Is this even close to what I should be messing with?  Also, does anyone have a good suggestion for where I can learn more about sprite images?  I'm having a hard time grasping the concept of sprites. ...

I have a polygon layer I am using as a querytask based on regional boundaries.  The polygon layer is our state, cut into 5 large pieces.  The county where the state offices are is a region unto itself, called central, which is completely surrounded by northwest region.  I have verified that the northwest region does exclude this central region, so I would call this a polygon with a hole in it, or maybe a multipart polygon. My problem is when I want to use the geometry of the northwest region polygon as input to a query and query task.  I'm first selecting the region from a pick list and determining the geometry.  This geometry is then used as input to a 2nd query task. The callback function from the initial queryTask: function showRegionResults (results) {         region = results.features[0].geometry;         map.setExtent(region.getExtent(), true);        findStaffInRegion(region);     } The 2nd query task which is populating a datagrid: function findStaffInRegion(region) {    var staffQueryTask = new esri.tasks.QueryTask(serverPathName + "/arcgis/rest/services/myService/MapServer/2"); //EUSstaff    var staffQuery = new esri.tasks.Query;    staffQuery.outFields = ["*"];    if (region) {    staffQuery.geometry = region;    staffQuery.spatialRelationship = esri.tasks.Query.SPATIAL_REL_CONTAINS;    staffQueryTask.execute(staffQuery);    dojo.connect(staffQueryTask, "onComplete", function(results){   var items = dojo.map(results.features, function(feature){             return feature.attributes;         });         var data = {                     identifier: "Contact_ContactId", //This field needs to have unique values                     label: "ID", //Name field for display. Not pertinent to a grid but used elsewhere.                     items: items                 };                 //Create data store and bind to grid.                 store = new dojo.data.ItemFileReadStore({                     data: data                 });                  var fp = dijit.byId('floater');                         if (fp.style.visibility=="hidden") {                             fp.style.visibility="";                             fp.show();                         }                 var staffGrid = dijit.byId('staffGrid');                 staffGrid.setStore(store);                 openFloatingPane();        });        }else{            console.log("region variable not defined")        } } This code works fine for all regions, except for the one that has the hole in it.  Is that type of polygon not a valid input geometry for a Query?  Am I misunderstanding what spatial relationship I should choose?  If I have to, I can run another function that excludes the features that are in the central region, but I'd rather not do that if I just have something wrong with this logic. ...

In the FLEX API, there is something called a composite symbol.  This let me layer two different lines or point symbols, which acted as one.  I used this extensively as a way to highlight a feature the user had selected, because I could take the existing symbol, but add a yellow highlight by adding a symbol larger than the current symbol. I don't see that anything at all like this is available in the Javascript API.  Am I missing this, or is this something that could possibly be added in the future? ... View more

All the examples I've seen for showing a loading have a listener set to the map.          dojo.connect(map,"onUpdateStart",showLoading);         dojo.connect(map,"onUpdateEnd",hideLoading); My project doesn't load the map at the beginning.  Instead, the users runs a query or find which generates a list.  Only after the list is displayed do they have the option to see the results of their query/find on a map.  It takes a moment for the page to open.  If the user selects a county or enters an address before it's fully initialized, they get errors. I feel like too much is still loading at the beginning.  I tried commenting out the dojo.addOnLoad(init) that most examples have because I know I don't need the map until the user makes some sort of selection.  Still it seems to be accessing the baselayers right when I start. I can add the loading image at start up by putting it in my top borderContainer, but I need to have something else besides the map's onUpdateEnd event to trigger the hideLoading function. http://wwwgis.dhss.mo.gov/Website/VCFprovider/provider.html ...
