Hi thanks for your reply..        I have gone through the sample but it is same as the above code as it also iterates through every service My problem is that I have about 10 services running and iterating through 10 services takes more time so my identify tool works slow, populating the layername from the results into the combobox take a long time about2 seconds for each ltem my code goes like this private void QueryPoint_MouseClick(object sender, ESRI.ArcGIS.Client.Map.MouseEventArgs e) {            // create identifyParams object             IdentifyParameters identifyParams = new IdentifyParameters()             {                 Geometry = mapPoint,                 //Tolerance = 50,                 MapExtent = mainPage.map.Extent,                 Width = (int)mainPage.map.ActualWidth,                 Height = (int)mainPage.map.ActualHeight,                 LayerOption = LayerOption.visible,                 SpatialReference = mainPage.map.SpatialReference             };                         // store all the available services in to myMapService stack             storeMapServices();             identifyTask.Url = myMapService.Pop();             identifyTask.ExecuteAsync(identifyParams, identifyParams);   } void identifyTask_ExecuteCompleted(object sender, IdentifyEventArgs e) {               if (e.IdentifyResults != null && e.IdentifyResults.Count > 0)             {                 boolNeedReset = false;                 //get Layerkeyfield and add identify results to dictionary                 ShowFeatures(e.IdentifyResults);                            }             if (tempInt < 2)             {                 identifyTask.Url = myMapService.Pop();                      IdentifyParameters identifyParams = e.UserState as IdentifyParameters;                 identifyTask.ExecuteAsync(identifyParams, identifyParams);             } }         public void ShowFeatures(List<IdentifyResult> results)         {             int intFeatureCount = 0;             //Get the Layer Key Field                        DataAccessService.DataAccessServiceClient dataAccessServiceClient = new DataAccessService.DataAccessServiceClient();            dataAccessServiceClient.getLayerKeyIDAsync(results[0].LayerName);           dataAccessServiceClient.getLayerKeyIDCompleted += ((s, e) =>            {                if (e.Result != string.Empty && e.Result != null)                {                    kvpLayerKeyField.Add(results[0].LayerName, e.Result);                    foreach (IdentifyResult result in results)                    {                        if (!kvpIdentifyResults.Keys.Contains(Convert.ToInt32(results[intFeatureCount].Feature.Attributes[e.Result])))                        {                            kvpIdentifyResults.Add(Convert.ToInt32(results[intFeatureCount].Feature.Attributes[e.Result]), results[intFeatureCount].LayerName);                            intFeatureCount++;                        }                    }                    //add identified layernames to combobox                    IdentifyComboBox.Items.Add(results[0].LayerName);                }            }); }                     Is there any other way to get mouse map pointer clicked element attributes form other then Identifytask? ...

Hey thank you soo much for the code it was of great help.. However as we are using multiple services the the iteration is more as it iterates completely for every service.. is there a way where I can reduce the time taken for execute the complete program? ... View more

thanx for the code it worked like a charm 🙂 Hi santoshf2, Which kind of projection are you using ? If you are using the "standard" projection of ArcGIS Server, the map is in WebMercator format. If you want to have a projection similar as Google or Bings, you must convert this format into WGS 84. There is a class on API to help you to make the convertion. See what I have do on my project : [PHP]        private WebMercator webMercator = new WebMercator();         private void OnMapMouseMove(object sender, MouseEventArgs e) {             if (Map == null) {                 return;             }             Point screenPoint = e.GetPosition(Map);             MapPoint webMercatorMapPoint = Map.ScreenToMap(screenPoint);             if (webMercatorMapPoint != null) {                 MapPoint wsg86MapPoint = (MapPoint)webMercator.ToGeographic(webMercatorMapPoint);                 Y = wsg86MapPoint.Y; // latitude in decimal                 X = wsg86MapPoint.X; // longitude in decimal             }         }[/PHP] If you wanted to show this result into degree/minute/second, you may easily find the good formula on google.

well I tried the above code but it does not seem to work.. can you please be a little more elaborate thank you with little changes the code worked fine.. the code goes like this             if (e.LayerItem.Layer.ID == "Districtsfl" && e.LayerItem.LegendItems != null)             {                 var legendItemsToDelete = e.LayerItem.LegendItems.Where(item => item.Label != "Districtsfl").ToList();               foreach(var item in legendItemsToDelete)                   if (item.Label != "Bagalkot")                   {                       e.LayerItem.LegendItems.Remove(item);                   }             } ...

The legend of a FeatureLayer doesn't contain any sub layers ==> we get the legend items (swatch+label) directly from the map layer item. So your code should be something like: if (e.LayerItem.Layer.ID ="Points of Interest" && e.LayerItem.LegendItems != null) {   var legendItemsToDelete = e.LayerItem.LegendItems.Where(item => item.Label != "WEBRIS.SPL_ROADS").ToList();   foreach(item in legendItemsToDelete)      e.LayerItem.LegendItems.Remove(item); } well I tried the above code but it does not seem to work.. can you please be a little more elaborate ...

The legend is not taking care of the current 'Where' clause. You can do this by code. Hook up an handler to the 'Refreshed' legend event and in this handler remove the legend items you don't want to see in the legend control. Hi thnx for the reply I used the following code            ESRI.ArcGIS.Client.Toolkit.Primitives.LayerItemViewModel removeLayerItemVM = null;             if (e.LayerItem.LayerItems != null)             {                 foreach (ESRI.ArcGIS.Client.Toolkit.Primitives.LayerItemViewModel layerItemVM in e.LayerItem.LayerItems)                 {                     //if (layerItemVM.LegendItems != null && layerItemVM.LegendItems.Any())                     //    layerItemVM.ImageSource = layerItemVM.LegendItems.First().ImageSource;                     e.LayerItem.LayerItems.Remove(removeLayerItemVM);                     if (layerItemVM.IsExpanded)                         layerItemVM.IsExpanded = false;                     if (layerItemVM.Label != "WEBRIS.SPL_ROADS")                         removeLayerItemVM = layerItemVM;                 }                 if (removeLayerItemVM != null)                     e.LayerItem.LayerItems.Remove(removeLayerItemVM);             }             else             {                 e.LayerItem.IsExpanded = false;             } I am able to get the layer name but I want to display only some subtype how do I do tat for eg under State I want to select/show only Alabama with symbol on the Legend am I missing something here? ...

Thank you for replying I am drawing data form oracle database thro ArSDE (my 1st theory is I am using Oracle 11g R2 with ArcSDE 9.3.1, the document shows sde support only for Oralce 11gR1 as am using 32 bit OS) Is this the problem I am also not able to Create routes(add Measure values) the process keeps running no message displayed should I change my server from Oracle 11gR2 to Oralce 11gR1 or may be use ArcSDE 10? ...
