You can't just add an arbitrary image to mapview because it's lack of additional information such as projection or coordinate system which the mapview needs. What you can do is download it and using it in ArcMap to generate a .tpk file, then you can load tpk file with the sdk. ... View more

Any information? I can't find samples about it. Thanks Technically speaking, YES. 1. You could derived from tiledlayer/tiledmapservicelayer and override its geturl method to load tiles of google maps. 2. You could using 3rd party application which already providing ArcGIS REST service from google maps, just like Portable Basemap Server, https://geopbs.codeplex.com/ However, google has restrictions of loading tiles without using its map api, FYI. ...

I asked a similar question on stack overflow here: http://stackoverflow.com/questions/5559219/whats-the-official-esri-solution-for-serving-up-static-map-images-i-e-png-jpg What I had come up with on my own was to enable WMS functionality on the map service, and then I was able to access the map directly via a URL.  There are no URL parameters for adding markers, but you can specify which layers should be visible - which can include your "markers." However, this seemed a bit kludgy to me, so I just put the question out there to see if there was an official ESRI solution.  The response I got shows a way to export the map service as an image using JavaScript.  This gets around having to enable the WMS functionality on the map service, but you still have to run javascript to get export the map and dynamically add an image with the src set to the output. I'd love to hear if anyone else has a "cleaner" solution. Thanks, Tom (W) Hi, you can just using the soap api here: http://services.arcgisonline.com/ArcGIS/sdk/soap/SOAP_Map_ExportMapImage.htm and add custom graphics to mapdescription before exporting an map image. ...

Actually, the Silverlight app does not compress these files for you. What you need to do is to make your result shapefiles into a zip file on server side, more specifically, these should be done as one part job of your geoprocessing service. You need to write python script to do this, grab your shapefiles as middle result, zip them into one file, and make this zip file as final gp service result to be downloaded. Here's sample code of how to zip and unzip files in python: http://help.arcgis.com/en/arcgisserver/10.0/help/arcgis_server_dotnet_help/0093/009300000037000000.htm ... View more

It's really not legal for directly using google maps' tile images in a third party app, including our Silverlight API. However, technically speaking you're possible to do this job easily by extending the TiledMapServiceLayer class, please refer: http://help.arcgis.com/en/webapi/silverlight/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.TiledMapServiceLayer.html If you are not interesting in the details, and just want to see the result in your Silverlight app, technically, you can try Portable Basemap Server: http://www.arcgis.com/home/item.html?id=48bf53da123e442ab8ac9aed52747552 It's provided a REST service url of google maps and this can be directly using in ArcGIS client api, such as ArcGISTiledMapServiceLayer. ...

It's possible to define a border style for a fill symbol. Just look at the Custom Fill Symbols in SymbolGallery here: http://help.arcgis.com/en/webapi/silverlight/samples/SymbolGalleryWeb/start.htm You'll notice that we could define the control template of a FillSymbol to customize its fill property. In the same way, we also can define its border in this way by using a Brush, ex. LinearGradientBrush. Because the Fill and BorderBrush property of FillSymbol are both silverlight Brush type. You could do such way: <esri:FillSymbol x:Name="CustomBorderFillSymbol" Fill="#66FF0000" BorderThickness="5">                 <esri:FillSymbol.BorderBrush>                     <LinearGradientBrush StartPoint="0,0" EndPoint="2,0"                          SpreadMethod="Repeat" MappingMode="Absolute">                         <GradientStop Color="Transparent" Offset="0" />                         <GradientStop Color="Transparent" Offset="0.499" />                         <GradientStop Color="#999" Offset="0.5" />                     </LinearGradientBrush>                 </esri:FillSymbol.BorderBrush>             </esri:FillSymbol> ...
