Setting Pop-up windows in the map

Hello,
I'm not sure if this thread belongs in this forum, but since I can't find the correct one and I'm using the silverlight API in my development I will post it here. If this isn't the correct forum please tell me which is, thank you.
I am trying to use the code sample for Web Map Dynamic Service Popups (http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#WebMapDynamicServicePopups). My problem is that the popup templates property in the dynamic layer is not enabled, so it shows the pop up window (with a little change in the code) but none of the information.
I tried enabling the pop up info using this help guide (http://help.arcgis.com/en/arcgisonline/help/index.html#/Configuring_pop_up_windows/010q0000004m000000/) and setting them is quite straitforward in the arcgis.com map (http://www.arcgis.com/home/webmap/viewer.html) but I can't save the chnages in my service.
I'm not sure if this is the right path or if I have to set the pop ups while creating the map, before I upload it to my server.

Thanks for your help.

but I can't save the chnages in my service.

For this particular aspect of your question, note that the arcgis.com viewer doesn't allow to save configuation (popoup, symbology...) at the service level. It is only possible at the map level.

To save at the service level, you can use ArcGIS Online Explorer.

I finally managed to get this working. The problem was I was loading the map service from my server instead of the GUID that the ArcGIS Explorer OnLine had set to my service. Also I had to make the service public.
Thanks for the help.

Hello, I managed to combine Identify a button in the toolbar that when I launch the application, the Identify window does not opens, until I click the button, it appears, empty

code:

</esri1:ToolbarItem>

what I want is that when I click the button nothing appears until I click on the map, then the Identify window opens with the information ...

I hope if someone can help me.

thank you very much.

Please, help me, someone have any idea

Hello,
Sorry for the delay in the answer, I've been off work for a couple of weeks. Your answer was very usefull and now I have the PopUp setting enabled in all the sublayer of my ArcGISDynamicMapServiceLayer service layer. Still, I'm having some trouble with the PopupTemplatesProperty as everytime I check my layer in code it tells me it's set to nothing. Am I missing something or I have to check some other property of the sublayers instead of the whole service?

Here's the code:

For Each layer As Layer In MapaGIS.Layers
 If layer.GetValue(Document.PopupTemplatesProperty) IsNot Nothing Then
  amsCapasMapa = TryCast(layer, ArcGISDynamicMapServiceLayer)
  idcDIccionario = TryCast(layer.GetValue(Document.PopupTemplatesProperty), IDictionary(Of Integer, DataTemplate))
  For Each linInformacionCapa As LayerInfo In amsCapasMapa.Layers
   If ((dblEscalaMapa > linInformacionCapa.MaxScale AndAlso dblEscalaMapa < linInformacionCapa.MinScale) OrElse (linInformacionCapa.MaxScale = 0.0 AndAlso linInformacionCapa.MinScale = 0.0) OrElse (dblEscalaMapa > linInformacionCapa.MaxScale AndAlso linInformacionCapa.MinScale = 0.0)) AndAlso idcDIccionario.ContainsKey(linInformacionCapa.ID) Then ' id present in dictionary
    intLayerID = linInformacionCapa.ID
    dtmInformacionCapa = idcDIccionario(linInformacionCapa.ID)
    Exit For
   End If
  Next linInformacionCapa
 End If
Next

Thank you.

Hello, I am back with another question.

I would like to join Identify fonction to a button in my toolbar, I want when I click that button and I click on the map, the Identify window opens with the information of the attribute. Identify window now appears always "empty" when I launch the application.

I had already tried with the function ToggleVisibilityAction:

<esri1:ToolbarItem x:Name="Identify" Text="Identify">
<esri1:ToolbarItem.Content>
<Button >
   <Image Source="i_identify.png" Stretch="UniformToFill"/>
                     <i:Interaction.Triggers>
                        <i:EventTrigger EventName="Click">
                              <local:ToggleVisibilityAction TargetName="IdentifyMap">
                               </local:ToggleVisibilityAction>
             </i:EventTrigger>
                      </i:Interaction.Triggers>
                 </Button>
</esri1:ToolbarItem.Content>
</esri1:ToolbarItem>

But when I specifies that the visivility = collapsed and I execute the program, the window does not appear to Identify initially, but when I click the button to open the window, the window of Identify will not open .. . the function of the button works when the visibility = visibile to close and pen the window when running the application.

I understand now, I just try it and it works, the service does not appear on the map, but the Identify function remains functional.

Thank you very much for your help,

I still waiting for your help, if you want!!!!

I am not sure I am clear on the issue. Calling a task you are giving it the Url of a service. This is done in C# code, you will always call the task from code. There is no reason that the service (url) that you call in code has to be defined in the map Xaml. In the sample applications you get a location based on a mouse click, once you have the MapPoint there is no longer anything that has to do with the map. If you remove the http://romulus/ArcGIS/rest/.../Continents/MapServer service layer from the map you can still use that Url in your identify task.

If you build a super service that has all you layers, when you create your identify task it is:

    IdentifyTask task = new IdentifyTask("http://romulus/arcgis/rest/AllLayerService/MapServer");
    //Your parameters define the sub layers used
    task.ExecuteAsync(parameters);

It does not matter if http://romulus/arcgis/rest/AllLayerService/MapServer is in the map or not.

Hope that helps,
-Joe

(and please feel free to give any posts you find helpful points by clicking the Up arrow)

Can you give me an example, please!? How I can call the service when operating the Identify tool without adding in the code and where place in the code??

I still waiting for your help, if you want!!!!

I made an error before, there is no reason why that service would need to be in your map and not visible. The service simply needs to exist on the server

Good luck

I will try to create a service that does not appear on my application, but only to operate the Identify tool and I will get back to you to inform you of the results. Thank you very much for your cooperation

You are not declaring your services separately, your services are your services. An IdentifyTask (as does any rest call) has a single rest endpoint. If you want to make calls into different services than you are making method calls on multiple rest endpoints. This is not something in the ESRI API causing a problem, this is how rest works. Tasks are simply convenient easy to use wrappers for rest method calls,

An option if you only want one IdentifyTask call would be to create a 'super' service that is not visible in the map. The IdentifyTask could be run against this service instead of needing to run against multiple services.

Hope that helps

Then,I must declare all my services separatly in C #:

C # code:

IdentifyTask identifyTask IdentifyTask = new ("http://romulus/ArcGIS/rest/.../Continents/MapServer"'

IdentifyTask identifyTask IdentifyTask = new ("http://romulus/ArcGIS/rest/.../Pays/MapServer");

IdentifyTask identifyTask IdentifyTask = new ("http://romulus/ArcGIS/rest/.../Communes/MapServer");

....

....

I do not believe the Identify task works with FeatureLayers, Identify operation is supported only with MapServices. If you enter the Url you are using into a browser and go to the bottom of the page you will see operations that are supported by that Rest service Url.

The general thinking behind the Identify task is to do a quick spatial search for features in multiple layers based on a location. It is along the lines of the Identify tool in ArcMap.

If you have numerous FeatureLayers you could run an Identify on every service that the FeatureLayers are part of passing in the LayerIds of the Layers you use in that Service. You would not need to do an Identify for every FeatureLayer, but you would have to do one for each of the services that contain your FeatureLayers (e.g. one for each of these...)

     http://romulus/ArcGIS/rest/services/Axeroute_Luxembourg/MapServer
     http://romulus/ArcGIS/rest/services/CENTRALITE_Administration_Etat/MapServer

Passing in the appropriate LayerIds as in my earlier post.

If your goal is to simplify the code in your Silverlight application you might want to look into creating a SOE or Geoprocessing task that does the work on the server with one call from your client.

This is my interface, I use separate FeatureLayer so I can appear the attribute table, download content "with id Layer"and make the zoom to layer, the Services contain a single layer separate from a service with URLs completely different

Hello, thank you four your help,

I just tried what you said and it works great. but in my case, I have an application that is aimed at a general public, thus:

1 - Part Layer option = LayerOption.visible ==> for me it's a good solution,     the Identify tool executes on the visible layers ...
2 - Now for my services, the service that I used above is only an example. my services are FeatureLayer separatly, i must use more then 20 FeatureLayer separatly,
a part of my service:

<esri:Map.Layers>

   <esri1:ArcGISTiledMapServiceLayer ID="StreetMapLayer"
    Url="http://server.arcgisonline.com/ArcGIS/rest/services/ESRI_StreetMap_World_2D/MapServer"/>

   <esri1:GroupLayer x:Name="GroupeLayer" ID="Bloomfield Hills" >

    <esri1:ArcGISDynamicMapServiceLayer ID="Parcels"
     Url="http://romulus/ArcGIS/rest/services/Limites/Monde/MapServer"/>

    <esri1:GroupLayer ID="Landuse Planning">

     <esri1:FeatureLayer ID="Points of Interest" Mode="OnDemand"
      Url="http://romulus/ArcGIS/rest/services/Communes_Luxembourg/MapServer"/>


     <esri1:FeatureLayer ID="Linear Features" Mode="OnDemand" Visible="False"
      Url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/BloomfieldHillsMichigan/LandusePlanning/MapServer/1" />


     <esri1:FeatureLayer ID="Planning Areas" Mode="OnDemand" Visible="False"
      Url="http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/BloomfieldHillsMichigan/LandusePlanning/MapServer/2"/>

     <esri1:FeatureLayer ID="Communes_Luxembourg3"
      Url="http://romulus/ArcGIS/rest/services/CENTRALITE_Administration_Etat/MapServer/2">
      <esri1:FeatureLayer.OutFields>
       <sys:String>*</sys:String>
      </esri1:FeatureLayer.OutFields>

     </esri1:FeatureLayer>

     <esri1:FeatureLayer ID="Axeroute_Luxembourg" Renderer="{StaticResource MySimplePointRenderer}"
      Url="http://romulus/ArcGIS/rest/services/Axeroute_Luxembourg/MapServer/0">

      <esri1:FeatureLayer.OutFields>
       <sys:String>*</sys:String>
      </esri1:FeatureLayer.OutFields>

     </esri1:FeatureLayer>

     <esri1:FeatureLayer ID="California"
      Url="http://romulus/ArcGIS/rest/services/Limites/Pays/MapServer">
      <esri1:FeatureLayer.OutFields>
       <sys:String>*</sys:String>
      </esri1:FeatureLayer.OutFields>

     </esri1:FeatureLayer>

    </esri1:GroupLayer>

   </esri1:GroupLayer>


</esri:Map.Layers>
</esri1:Map>

And when I do what you told me on one of these FeatureLayer, its not working.

Now I want to know how I will do for the Identify tool works on all my FeatureLayer or for GroupeLayer, I must declared them separatly in c #?
like this:

IdentifyTask identifyTask = new IdentifyTask("http://romulus/ArcGIS/rest/services/CENTRALITE_Administration_Etat/MapServer/2")
GraphicsLayer graphicsLayer = MyMap.Layers["Communes_Luxembourg3"] as GraphicsLayer;

IdentifyTask identifyTask = new IdentifyTask("http://romulus/ArcGIS/rest/services/Axeroute_Luxembourg/MapServer/0");
GraphicsLayer graphicsLayer = MyMap.Layers["Axeroute_Luxembourg"] as GraphicsLayer;

..........for all FeatureLayer???????

thank you for your help.

In your code you setup your IdentifyParameters as such:

        private void QueryPoint_MouseClick(object sender, ESRI.ArcGIS.Client.Map.MouseEventArgs e)
        {
            MapPoint clickPoint = e.MapPoint;

            IdentifyParameters identifyParams = new IdentifyParameters()
                                                    {
                                                        Geometry = clickPoint,
                                                        MapExtent = MyMap.Extent,
                                                        Width = (int) MyMap.ActualWidth,
                                                        Height = (int) MyMap.ActualHeight,
                                                        LayerOption = LayerOption.visible,
                                                        SpatialReference = MyMap.SpatialReference,
                                                    };

            IdentifyTask identifyTask = new IdentifyTask("http://romulus/ArcGIS/rest/services/...../Monde/MapServer")
            identifyTask.ExecuteCompleted += IdentifyTask_ExecuteCompleted;
            identifyTask.Failed += IdentifyTask_Failed;
            identifyTask.ExecuteAsync(identifyParams);
        }

In this code you set the Identify task to return values for all visible layers because LayerOption = LayerOption.visible.

If instead you setup the parameters like this


        private void QueryPoint_MouseClick(object sender, ESRI.ArcGIS.Client.Map.MouseEventArgs e)
        {
            MapPoint clickPoint = e.MapPoint;

            IdentifyParameters identifyParams = new IdentifyParameters()
                                                    {
                                                        Geometry = clickPoint,
                                                        MapExtent = MyMap.Extent,
                                                        Width = (int) MyMap.ActualWidth,
                                                        Height = (int) MyMap.ActualHeight,
                                                        SpatialReference = MyMap.SpatialReference,
                                                    };

            identifyParams.LayerIds.Add(2);


            IdentifyTask identifyTask = new IdentifyTask("http://romulus/ArcGIS/rest/services/...../Monde/MapServer")
            identifyTask.ExecuteCompleted += IdentifyTask_ExecuteCompleted;
            identifyTask.Failed += IdentifyTask_Failed;
            identifyTask.ExecuteAsync(identifyParams);
        }

Where instead of setting a value for LayerOptions like in the first example you add Ids to the LayerIds collection


         identifyParams.LayerIds.Add(2);

Now when the Identify task runs it will only search fro result from LayerId = 2. This way you can use a service with many layers but only return identify results from one (or any subset), which seems to be what you want to do

Hope that helps

Maybe I had asked a wrong question , I'll explain, I used the code of Samples "Identify" and it's work good with a service that contains several layers, but what I want is how to declare services that contain a single layer in a service.

and i tried to display the code with a service that contains a single layer and its not working. how and where i must declare my service.

Code:

Hello, I managed to make the sample "Identify" from API Silverlight in my application with a service that contains several layers:

Code:

IdentifyTask identifyTask = new IdentifyTask("http://romulus/ArcGIS/rest...../Monde/MapServer")

But in my application, I would be obliged to work with multiple services and each service contains a single layer, for example, to display their attribute table, then when I wanted to test the tools with a service that contains a single layer, it does not work:

Example of Feature Layer: Code:

IdentifyTask identifyTask = new IdentifyTask("http://romulus/ArcGIS/rest/services/CENTRALITE_Administration_Etat/MapServer/2")

So what to do in case I want the Identify fonction on all services that I declared in my Group Layer?

Please help me if you have ideas.

The IdentifyParameters object that you use with the IdentifyTask::ExecuteAsynch methods has a LayerIds property which is a List<int> and this defines which layers to use in the Identify task

    parameters.LayerIds.Add(2);
    identifyTask.ExecuteAsynch(parameters)

Would return only features from the layer with LayerId=2.

Hope that helps,
-Joe

Hi jennifer, thank you so much for your answer,

Yes I had already tried it and it work, but that's not what I want,
I want when I'd click on a layer I can visualized the attribute information in a window like MapTip of Toolkit_Control and I would like to do this for more than 50 FeatureLayers, so I do not redo the code 50 times for every FeatureLayer, I want something for the Groupe Layer and when i click in the map, not a hover ove.

If you want all the fields to show in FeatureLayer MapTip, you can use the following code.

   <esri:FeatureLayer ID="MyLayer" OutFields="*"
          Url="yourServiceUrl">
    <esri:FeatureLayer.MapTip>
     <Grid>
      <Grid.ColumnDefinitions>
       <ColumnDefinition Width="Auto"/>
       <ColumnDefinition Width="*"/>
      </Grid.ColumnDefinitions>
      <ItemsControl ItemsSource="{Binding Keys}" Grid.Column="0" />
      <ItemsControl ItemsSource="{Binding Values}" Grid.Column="1" />
     </Grid>
    </esri:FeatureLayer.MapTip>
   </esri:FeatureLayer>

I'm still waiting a response from you

Thank you.

Finally, I am pleased that you are there Dominique.

I just remove the cluster and it work, now I asked another question is how to make appear the information of an attribute from attribute table and make it for all my layers, not just a single layer, I want something automatic on group layers and that I made �??�??them appear all the attribute fields.

I hope I explained what I'm trying to do and for more precision, I would like when I click on an attribute that makes them appear to in a window as the sample of the MapTips Toolkit Controls without the "hover":

http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#MapTipWidget

May be as the result of "identify" too, if you click on several different attribute layer, you can pass in the window of an attribute from one layer to another, but not in a large window, in a window like MapTips-Toolkit Controls.

Thank you for your cooperation, your help and time.

Likely you don't need the cluster that is set in the sample --> remove it (else it's probably a casing error : FeatureLayer .Clusterer)

I managed to do a feature on the MapTips layer as this example:

http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#FeatureLayerMapTips

Now I want to know how to do it on all the layers I have and I wish I made �??�??them appear all the fields in each layer as result of this example:

[url]http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#MapTipWidget.

Without specification of a one field or two, I want to make �??�??them appear all the fields of the attribute on which i click.

Since you create your feature layers in XAML, you can define your maptips in XAML as well without any c# code.
There are samples here :

http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#FeatureLayerMapTips

http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#GraphicsMapTip

Please, I am not strong in programing, I need help, please

this is my code :

in XAML :

<esri1:Map x:Name="MyMap" ExtentChanged="MyMap_ExtentChanged" Margin="274,23,14,160" VerticalContentAlignment="Stretch"
     HorizontalContentAlignment="Stretch" Padding="0" Grid.Row="1" IsLogoVisible="False" WrapAround="True" MouseClick="MyMap_MouseClick" >
