If you go to the Code Gallery on the main Silverlight API page and search for print the are a number of samples that come up.  If you can hold off a bit I would wait for 10.1 to be released as this has native print support as part of AGS ... View more

I am not exactly clear on what you are describing with how the map is exposed in you view model.  You descriptions sounds as though you have a Layers collection on the ViewModel that is bound to the map in Xaml.  Something along these lines below. <esri:Map x:Name="MyMap" WrapAround="True" Extent="-15000000,2000000,-7000000,8000000" Layers="{Binding MapLayers}"> I have found that it is pretty much impossible to really create an ESRI Silverlight API application without exposing the Map object to the ViewModel, there are just too many things that need the Map object.  What I do is have my main page implement an interface that exposes the Map.     public interface IMapView     {         Map Map { get; }     } I use Dependency Injection (I use MEF, Unity is another Microsoft option) to get my IMapView object into my ViewModels.  I don't actually have a ViewModel attached to the MainPage, instead my MainPage is made of numerous views each with it's own ViewModel. From here I would have a View (some kind of toolbar in this case) with an attached ViewModel.  For a good navigation tool you kind of need toggle buttons, in my opinion.  I have made those as custom controls that inherit from RadioButton.  RadioButton because it already includes the behavior of only one being selected at a time, compared to core ToggleButton.  There are a few ways to wire the commands, the most straight forward is to have the ViewModel expose an ICommand for each button and a bool for the IsSelected property.  Something similar to below                 <Buttons:MyToggleButton Text="{Binding Path=LanguageResource.ButtonText, Source={StaticResource LocalizedStrings}}"                                                IsChecked="{Binding ZoomInIsChecked, Mode=TwoWay}"                                                Click="{Binding ZoomCommand}" CommandParameter="ZoomIn" GroupName="ZoomButtons"/>         [Import]         public IMapView MapView {get;set;}         private ICommand _zoomCommand;         public ICommand ZoomCommand         {             get { return _zoomCommand?? (_zoomCommand= new DelegateCommand<string>(ExecuteZoomCommand)); }         }         private void ExecuteZoomCommand(string zoomType)         {              //Here would be my zoom logic         } Something along those lines ties the Command to the view model Hope that helps ...

ESRI changed these to match with Google and Bing which use WebMercator.  This way the tiling scheme is the same for all the primary base maps sources.  I cannot see that they would ever change back to WGS as it would mean having to support two different sets of cached maps. I agree that WGS84 makes a lot more sense to use as a projection ... View more

Yassine, Sorry about the variable name error, the sample was not actually meant to be used as is, it was intended to show the two possible ways to setup the code depending on if a user was allowed to select only one row, or select more than one row I do not think I am clear about what you are trying to zoom to. What I thought you wanted to do is select a number of points in your map using a spatial query.  For example, you would draw a box around a number of points and those points would then show up in the selected points datagrid.  Then when you select an item in the data grid it would zoom to that point.  So every time you click an item in the grid it zooms to a location on the map. For the sample I changed the code to this:         private void QueryDetailsDataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e)         {             foreach (Graphic g in e.AddedItems)             {                 g.Select();                 MyMap.ZoomTo(g.Geometry);             }             foreach (Graphic g in e.RemovedItems)                 g.UnSelect();         } Which will now zoom to the state that was selected when the user clicks on the item in the datagrid. Can you please try to clarify if this is what you are trying to do.  I think that your goal is different from my understanding. Thanks -Joe ... View more

You can create a value converter that returns the image URL depending on the field values. Then you can bind the image inside the maptip to the Url coming from this converter. Interesting idea, thanks. ... View more

What you are showing does not have anything to do with binding or MVVM so am not sure why are discussing it in that context. In the first line of you code you assign a variable to the GraphicsSource property and so you now have two variables reference that same object.  When you make changes to the _graphics variable it is reflected in the GraphicsSource because they both reference that object. When you set _graphics = new ... The _graphics variable now references a new object.  The original object that GraphicsSource is referencing has not been affected, GraphicsSource still references the same object it has the entire time. What it seems like you want is to have an object bound to the GraphicsSource.        <esri:GraphicsLayer ID="GL" GraphicsSource="{Binding GraphicsSource, Mode=TwoWay}" /> If you have a class like below that is set as the DataContext for your the GraphicsLayer (e.g., through setting the DataContext on the View with the map in it)     public class MyViewModel : INotifyPropertyChanged     {         private ObservableCollection<Graphic> _graphicsSource;         public ObservableCollection<Graphic> GraphicsSource         {             get { return _graphicsSource; }             set             {                 _graphicsSource = value;                 PropertyChanged("GraphicsSource");             }         }         #region Implementation of INotifyPropertyChanged         public event PropertyChangedEventHandler PropertyChanged;         private void OnPropertyChanged(string propertyName)         {             if ( PropertyChanged != null )             {                 PropertyChanged(this, new PropertyChangedEventArgs(propertyName));             }         }         #endregion     } Now something like this would reset the graphics to those contained in someOtherGraphics and it would be reflected in the map         private void ExecuteNewGraphicsCollection()         {             GraphicsSource = new ObservableCollection<Graphic>(someOtherGraphics);         } Hope that helps ...

In the code example from the sample you pointed to the SelectionChanged Event returns a Graphic collection (IList) as shown below e.AddedItems.         private void QueryDetailsDataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e)         {             foreach (Graphic g in e.AddedItems)                 g.Select();             foreach (Graphic g in e.RemovedItems)                 g.UnSelect();         } The Graphic object has a Geometry property and your case because you selected points this Geomtry would be a MapPoint object.  Something like this below should get the MapPoint you need         private void QueryDetailsDataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e)         {             //This would work with multiple points being selected             ESRI.ArcGIS.Client.Geometry.PointCollection points = new ESRI.ArcGIS.Client.Geometry.PointCollection();             foreach ( Graphic g in e.AddedItems )             {                 MapPoint mapPoint = g.Geometry as MapPoint;                 if (mapPoint != null )                 {                     points.Add(mapPoint);                 }             }             MultiPoint multiPoint = new MultiPoint(points);             MyMap.ZoomTo(multiPoint.Extent);             //If you user was only allowed to select a single point it would be something like this              Graphic g = e.AddedItems[0] as Graphic;              MapPoint mapPoint = g.Geometry as MapPoint;              if (mapPoint != null )              {                    MyMap.ZoomToResolution(MyMap.Resolution / MyMap.ZoomFactor, mapPoint);  //As shown Above               }             foreach (Graphic g in e.RemovedItems)                 g.UnSelect();         } Hope that helps -Joe ...

Well it seem it is something to do with when running from IIS you must treat the connection like an internet connection to the service catalog and not like a LAN connection.  I changed my PropertySet from setting machine name to setting Url and not it is working Cheers ... View more

Patrick, Thanks for the response, after I posted I guessed that might be the solution as it is a similiar approach for managing an AGS from another machine without a domain.  Just had to convince the IT guys here that it was necessary so they would setup the account 🙂 Thanks again -Joe ...

Your solution does work but it is still causing me a problem that I am not resolving.  I moved some of my imagery over to the local disk and built the services from there and it all works.  However, I am still having an issue when the imagery is stored on a network share.  I have checked and the "Everyone" user has read permissions to this folder, but the issue still exists. Is there a special way that permissions need to be set on a network share so that the SOC will have the appropriate access?  My SOC user is not a domain user only a local user on the AGS machine, I am not sure if I will need to make the user a domain user (that seems like an odd requirement to me).  Is there something else I am missing?
