WMS layer in Silverlight app

JayKappy

I am trying to display a WMS layer being published from a 3rd party source...

I tried this but am getting errors saying that the type cannot be found and that I might be missing an assembly reference??? If missign a reference, how teh heck do I know what reference to add for this? Is there soem location that explains what references are needed for what?

<esriWMS:WMSMapServiceLayer ID="WMS Layer" Layers="2909_17518_bg" Url="http://aes.gsfc.nasa.gov/cgi-bin/wms" Opacity="0.7"></esriWMS:WMSMapServiceLayer>

Any thoughts or additional info on displaying WMS services?

THANKS

can you tell me how did you get the WMSMapServiceLayer?

The WMS Layer is called 'WmsLayer' and not 'WmsMapServiceLayer'.
There is a sample of usage here : http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#WmsLayerSimple

I used ESRI.ArcGIS.Client.Toolkit.DataSources to my application. but it is not work.can you tell me how did you get the WMSMapServiceLayer?

JayKappy

I thank you all for your efforts....it turns out there was soemthing wrong with the data...they no have it stright and its showing up....
Thanks...very appreciated

It will only be able to autoproject if that service supports the WKID of your map (for instance most non-ArcGIS servers doesn't support 102100 that ArcGIS Server uses for WebMercator)

Are these service set up to be consumed by webapp's? If I open fiddler and attempt to connect I get errors regarading "/clientaccesspolicy.xml" and "/crossdomain.xml".

JayKappy

This is what I did...errors are gone but nothign is showing up...I am contacting the 3rd party to see if soemthign is messed up on their end...
I thank you for that...I missed the WMS example...I was getting my prior code from another website..

I believe their data is WGS 84, but it shoudl auto project right?

' MAIN PAGE .xaml

<esri:WmsLayer ID="LOGISLAYER" 
 Url="http://gis.logis.org/ArcGIS/services/MG_TEST/MapServer/WMSServer"          
 Initialized="WmsLayer_Initialized2"/>

MAIN PAGE vb.xaml

    Private Sub WmsLayer_Initialized2(ByVal sender As System.Object, ByVal e As System.EventArgs)
        Dim myWmsLayer As ESRI.ArcGIS.Client.Toolkit.DataSources.WmsLayer
        myWmsLayer = TryCast(MyMap.Layers("LOGISLAYER"), ESRI.ArcGIS.Client.Toolkit.DataSources.WmsLayer)        
        ' You can control the visibility of which WMS layers are displayed by adding the
        ' sub-LayerID's to the String Array. 
        Dim myVisibleWmsLayers() As String = {"0"}
        myWmsLayer.Layers = myVisibleWmsLayers
    End Sub

Have you looked at this sample? http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#WmsLayerSimple

Notice that in the xaml, the following xaml namespace definition was added.

    xmlns:esri="http://schemas.esri.com/arcgis/client/2009">

which allows for the following code to work:

            <esri:WmsLayer .../>

I also tried your code and it works for me. Have you check project references the correct assembly? ESRI.ArcGIS.Client.Toolkit.DataSources.dll?

JayKappy

I went into Add References and Added ESRI.ArcGIS.Client.Toolkit.DataSources reference
I then added this to the User Control

xmlns:esriWMS="clr-namespace:ESRI.ArcGIS.Client.Toolkit.DataSources;assembly=ESRI.ArcGIS.Client.Toolkit.DataSources"

This is the WMS in the Map

<esriWMS:WMSMapServiceLayer ID="AGSWMSLayer" 
Url="http://sampleserver1.arcgisonline.com/ArcGIS/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer/WMSServer"   
SkipGetCapabilities="True"
Layers="2" Version="1.3" Opacity="0.7"/>

But then I get a bunch of errors:
1. The type esriWMS:WMSMapServiceLayer was not found, missing assembly reference
2. The TAG WMSMapServiceLayer does not exist in XML namespace "clr-namespace:ESRI.ArcGIS.Client.Toolkit;assembly=ESRI.ArcGIS.Client.Toolkit.DataSource"

Any more thoughts?

Thanks

JayKappy

How do you know that? Is there some place to look that up?.......

THanks

DominiqueBroux

WMSLayer is defined in ESRI.ArcGIS.Client.Toolkit.Datasource so you need to include it in your project.
