Try calling WebRequest.RegisterPrefix("http://MyServer/ArcGIS/REST", WebRequestCreator.ClientHttp) when your app starts (before the map initializes). If that doesn't help, see this blogpost: http://blogs.esri.com/Dev/blogs/silverlightwpf/archive/tags/security/default.aspx ... View more

If you are getting a blank page, an exception was thrown. Make sure you have debug set up right, and you should be getting the exception in VS. Usually these exceptions occur when you have errors in your XAML. If you are using IE, you might also be able to see the error but double-click the warning icon in the lower left corner. Lastly, this doesn't seem like a working service: http://www.ngdc.noaa.gov/eog/maps/cgi-bin/public/ms/gcv2/?service http://maps.gov.nl.ca/gsdw/rest/serv...ries/MapServer doesn't have a crossdomain.xml or clientaccesspolicy.xml file in place so you will not be able to access it from Silverlight without using a proxy. It's actually likely that the blank page/exception is thrown because the layer couldn't initialize. Try putting a InitializationFailed event handler on the layers and see of those are hit. ...

Sorry. The zooming behavior is by design. You might be able to intercept the mousewheel zoom and cancel it so it doesn't bubbles to the map. You can then do the Zoom call yourself. ... View more

Before you go down this road, I'm wondering why you are not using a GraphicsLayer ? There's nothing in this post (or your other one) that makes use of something the GraphicsLayer couldn't very easily do. ... View more

I'm not sure I understand the problem. When you zoom, the mouse zooms around where the mouse cursor is (ie. if you hold the mouse on top of a city and zoom, the city will stay under the mouse cursor). There shouldn't be any panning involved. ... View more

If you need to lock down the service, it's probably better just to create different services, and secure them using token services. That way you don't really have to do anything on the client other than provide a login screen to get the token. ... View more

Listen for ExtentChanged/ExtentChanging. If your user moves out of the extent, zoom/pan back. ... View more

This line : esri:ElementLayer.Envelope="0,0,0,0" means "show the image at equator/greenwich with the size of the image (which you never set width/height on - you should)". When you change it to -30,30,-30,30, this means its still centered on equator/greenwich, but now 60map units wide and high (width/height of image will be overridden. However you are zooming to -103.0947, 21.07186, 58.95613, 68.22523, which doesn't intersect -30,30,-30,30. Other things to check: Is your image path correct? ... View more

I wouldn't recommend using SOAP to ArcGIS Server. The proxy generated is enourmous, and the overhead is even bigger (no caching at all). It just doesn't scale very well. Have you looked at this approach instead: http://resources.esri.com/arcgisserver/apis/silverlight/index.cfm?fa=codeGalleryDetails&scriptID=16800 ... View more

You can use the userstate parameter in the ExecuteAsync to pass in an object that identifies the layer, for instance the layer instance, Layer ID or index (...or all of them in an array or custom class/struct etc). This is what the e.UserState value will contain when the request returns. This is very similar to how for instance the methods in System.Net.WebClient works. ... View more

We are aware of this issue in the beta, and it will be fixed in the upcoming release. ... View more

Default settings are usually set for maximum performance. This means that for certain scenarios (like this) you might have to tweak the defaults. ... View more

In that case don't print the map, but print a control that contains a map plus header etc. ... View more
