Ben, You could probably use a TargetedTriggerAction instead of Behavior since you don't need to store any state between the actions. The code would look like this: public class MouseCoordinatesAction :TargetedTriggerAction<TextBlock>     {         /// <summary>         /// Invokes the action.         /// Search for the user provided address         /// </summary>         /// <param name="parameter">The parameter to the action. If the Action does not require a parameter, the parameter may be set to a null reference.</param>         protected override void Invoke(object parameter)         {             if ((Target != null) && (parameter != null))                 Target.Text = GetCoordinateString(parameter as MouseEventArgs);         }         private string GetCoordinateString(MouseEventArgs e)         {             string mouseCoordString = string.Empty;             Map map = AssociatedObject as Map;             Point mouseLoc = e.GetPosition(map);             MapPoint coordLoc = map.ScreenToMap(mouseLoc);             if (coordLoc != null)             {                 WebMercator webMercator = new WebMercator();                 MapPoint latLon = webMercator.ToGeographic(coordLoc) as MapPoint;                 mouseCoordString = string.Format("Lon {0:F4}° Lat {1:F4}°", latLon.X, latLon.Y);             }             return mouseCoordString;         }     } <Grid x:Name="LayoutRoot">         <esri:Map x:Name="map_BaseMap" Layers="{Binding Path=MapLayers}" helpers:MapHelper.ZoomGeometry="{Binding Path=MapExtent}" MinimumResolution=".25">             <esri:Map.Extent>                 <esri:Envelope XMin="-10510990.377700" YMin="5586273.272800" XMax="-10364472.557100" YMax="5682307.505400">                     <esri:Envelope.SpatialReference>                         <esri:SpatialReference WKID="102100"/>                     </esri:Envelope.SpatialReference>                 </esri:Envelope>             </esri:Map.Extent>             <interactivity:Interaction.Triggers>                 <interaction:EventTrigger EventName="MouseMove">                     <actions:MouseCoordinatesAction TargetName="mouseCoordinates" />                 </i:EventTrigger>         </esri:Map>         <controls:LogisNavigation Margin="5" Map="{Binding ElementName=map_BaseMap}" FullExtentGeometry="{Binding Path=FullExtent}"                                   InitialExtentGeometry="{Binding Path=InitialExtent}" helpers:NavigationHelper.ZoomReset="{Binding Path=MapExtent}"                                   Background="Gray" BorderBrush="White" Foreground="Black"/>         <esri:MapProgressBar HorizontalAlignment="Center" VerticalAlignment="Bottom" Margin="0,0,0,5" Width="150" Map="{Binding ElementName=map_BaseMap}"/>         <controls:LogisScaleBar HorizontalAlignment="Left" VerticalAlignment="Bottom" Margin="5" Width="200" MapUnit="Meters"                                 Map="{Binding ElementName=map_BaseMap}"/>         <TextBlock x:Name="mouseCoordinates" HorizontalAlignment="Center" VerticalAlignment="Top" Margin="5" Foreground="White"/>     </Grid> Add a namespace in your xaml file xmlns:interaction="clr-namespace:Microsoft.Expression.Interactivity.Core;assembly=Microsoft.Expression.Interactions" And the TargetName of your action is the name of the TextBlock, where you want to display the coordinates.

We don't know what kind of errors you get, but here is a thread discussing deployment: http://forums.arcgis.com/threads/16706-server-500-error?highlight=asp.net Just a few pointers: 1. Make sure your deployment website is configured as Application 2. If you have used .Net framework 4.0 to develop the application, confirm that ASP.Net 4 is installed on the web server (see the threads for details). 3. Is your web server configured for Silverlight applications: http://learn.iis.net/page.aspx/262/configuring-iis-for-silverlight-applications/ Post your error, or search your error in Google (or other search engines) to see what the problem might be. Good Luck! ... View more

Jerry, Can you debug and find out which object is null? Is it "graphic" or the Shape attribute? While debugging, check to see what is the value of findResult.LayerName if you are searching multiple layers. It could be only one layer causing the error. Also, you could go to your service in the REST Services directory, and perform Find there. http://yourservername/arcgis/rest/services/yourmapservicename Scroll all the way down to the page and click on Find. Use the API Reference link in the upper right corner to see what parameters you need to provide. See if you get geometry back when Return Geometry is true.  Make sure that all layers you are searching have the Shape field (to see the fields of each layer go to the above page and click on each layer link to see their metadata). Good Luck! ... View more

Jerry, Have you tried adding: findParameters.ReturnGeometry = true; somewhere before: findTask.ExecuteAsync(findParameters); The default is "true" in this version of the API, but I cannot recall what it was in previous versions. It looks like your Shape attributes come back null, so give it a try. Good Luck! ... View more

Raffi, In the links above, I see a second parameter to the pushView method, which is the data that you want to pass. Maybe, this what you are missing. Another link: http://www.unitedmindset.com/jonbcampos/2010/10/25/flex-4-5-mobile-development-post-burrito/ Good Luck! ... View more

Hi Raffi, My Flex is getting kind of rusty, and you know I haven't done anything mobile, but here are some links that might help  you: http://help.adobe.com/en_US/flex/mobileapps/WSa122979b4619725672e48c412a3e152164-7fff.html#WSe11993ea1bd776e577ad4b2d12a42c5858a-7fff http://cookbooks.adobe.com/post_Passing_data_between_Views-18854.html 😄 P.S. I just open your link, you are using the second approach. Have you tried the first (which is explained in the links above): http://devgirl.org/2011/08/09/flex-mobile-development-passing-data-between-tabs-part-1-includes-source/ ... View more

Gabriel, This should work: var states = (from g in args.FeatureSet.Features                    select g.Attributes["STATE_NAME"]).Distinct().OrderBy(s => s); QueryComboBox.ItemsSource = states; Simply remove the foreach loop, and Items.Add replace with ItemsSource. Or you could do it this way too: string[] states = args.FeatureSet.Features.Select(s => s.Attributes["STATE_NAME"].ToString()).Distinct().OrderBy(t => t).ToArray(); QueryComboBox.ItemsSource = states; Here is an article on using Linq with Distinct and Order By: http://programminglinq.com/blogs/marcorusso/archive/2008/07/20/use-of-distinct-and-orderby-in-linq.aspx Hope, it works! ...

Gabriel, I know I am replying a little late (it's summer time), but you can either add the checkbox handlers in code behind in Map_Loaded instead in xaml, or you can check in the Check/Uncheck event handlers if the Map object is null, and skip the code if it is. Cluster cluster; private void Map_Loaded(object sender, RoutedEventArgs e)         {                         GraphicsLayer gl = Map.Layers["QueryGraphicsLayer"] as GraphicsLayer;             //preserve the clusterer object to use it when you want to turn the clusering back on             cluster = gl.Clusterer;      //this is the symbol to be used for the single points that don't get clustered             //it can be defined in your xaml, or you can difine it in code      //if it is in your xaml you get it this way:             SimpleRenderer simpleRenderer = LayoutRoot.Resouces["simpleRenderer"] as SimpleRenderer;             //you can use a UniqueValueRenderer also, or not use anything             //if you don't specify the renderer, the single points will be red circles (I think)             gl.Renderer = simpleRenderer;             clusterCheckBox.Checked += new RoutedEventHandler(clusterCheckBox_Checked);             clusterCheckBox.Unchecked += new RoutedEventHandler(clusterCheckBox_Unchecked);                     } private void clusterCheckBox_Unchecked(object sender, RoutedEventArgs e)         {             //check first if Map is null             if (Map == null) return;             GraphicsLayer gl = Map.Layers["QueryGraphicsLayer"] as GraphicsLayer;             //check if gl is null             if (gl == null) return;             gl.Clusterer = null;             UniqueValueRenderer uniqueRenderer = LayoutRoot.Resources[QueryUniqueValueRenderer"] as UniqueValueRenderer;             gl.Renderer = uniqueRenderer;                      } private void clusterCheckBox_Checked(object sender, RoutedEventArgs e)         {             //check first if Map is null             if (Map == null) return;             GraphicsLayer gl = Map.Layers["QueryGraphicsLayer"] as GraphicsLayer;             //check if gl is null             if (gl == null) return;             GraphicsLayer gl = Map.Layers["QueryGraphicsLayer"] as GraphicsLayer;             gl.Clusterer = clusterer;             SimpleRenderer simpleRenderer = LayoutRoot.Resouces["simpleRenderer"] as SimpleRenderer;             gl.Renderer = simpleRenderer;                               }. In your xaml remove the event handlers on the checkbox: Checked="clusterCheckBox_Checked" and Unchecked="clusterCheckBox_Unchecked". Hope this works! Good Luck! ... View more

Hi Gabriel, Here is one way to do this: Cluster cluster; private void Map_Loaded(object sender, RoutedEventArgs e)         {                         GraphicsLayer gl = Map.Layers["QueryGraphicsLayer"] as GraphicsLayer;             //preserve the clusterer object to use it when you want to turn the clusering back on             cluster = gl.Clusterer;      //this is the symbol to be used for the single points that don't get clustered             //it can be defined in your xaml, or you can difine it in code      //if it is in your xaml you get it this way:             SimpleRenderer simpleRenderer = LayoutRoot.Resouces["simpleRenderer"] as SimpleRenderer;             //you can use a UniqueValueRenderer also, or not use anything             //if you don't specify the renderer, the single points will be red circles (I think)             gl.Renderer = simpleRenderer;                     } private void clusterCheckBox_Unchecked(object sender, RoutedEventArgs e)         {                         GraphicsLayer gl = Map.Layers["QueryGraphicsLayer"] as GraphicsLayer;             gl.Clusterer = null;             UniqueValueRenderer uniqueRenderer = LayoutRoot.Resources[QueryUniqueValueRenderer"] as UniqueValueRenderer;             gl.Renderer = uniqueRenderer;                               } private void clusterCheckBox_Checked(object sender, RoutedEventArgs e)         {                         GraphicsLayer gl = Map.Layers["QueryGraphicsLayer"] as GraphicsLayer;             gl.Clusterer = clusterer;             SimpleRenderer simpleRenderer = LayoutRoot.Resouces["simpleRenderer"] as SimpleRenderer;             gl.Renderer = simpleRenderer;                               } Good Luck!

Lisa, I haven't followed the logic of adding the layers to the MapLayerCollection, but I noticed that here: public LayerCollection MapLayerCollection         {             get { return mapLayerCollection; }             set             {                 if (mapLayerCollection != value)                 {                     mapLayerCollection = value;                                        RaisePropertyChanged("LayerCollection");                 }             }         } the parameter of the RaisePropertyChanged method is "LayerCollection", and I believe it should be "MapLayerCollection". Hope, that's all you have to fix. Debug to make sure the MapLayerCollection gets populated as you expect. Good Luck! ... View more
