Any version will do with Server 9.3.1, but as Jennifer mentioned, you won't be able to take advantage of a lot of the v2.0 features that relies on ArcGIS Server 10.- ... View more

There's almost no limit to how advanced you can make the point symbols in Silverlight/WPF. For an example check out the symbol gallery: http://help.arcgis.com/en/webapi/silverlight/samples/SymbolGalleryWeb/start.htm ... View more

When you say "All information" how much data are we talking about? (record count, geometry type/complexity and attributes). Are you using the default rendering coming from ArcGIS server or are you using some kind of custom rendering and/or symbol? Some symbols can be extremely expensive if used "wrong". On a side note, it's worth noting that Silverlight's Garbage Collector is extremely lazy (it really only kicks in if it has to), so the amount of memory that Task Explorer is telling you that Internet Explorer is using can be very misleading. ...

Actually v2.1 has events you can use to "intercept" the tile before (TileLoading) and after it loads (TileLoaded). In the case of "before it loads" you check if the tile is already stored locally and if so, you set the tilesource on the event argument, and the map will use that. If you don't have it, do nothing here. In the TileLoaded handler you can then get to the byte stream that the tile was made off, and you can save it to disk for use at a later time when TileLoading for this tile fires again. I've seen prototypes of this working for WPF and Silverlight in Full Trust mode (it will not work with SL if you are not in full-trust mode). You can even modify the tile in the TileLoaded event and for instance watermark it, or replace any tile load failure (see the event args for that) with a tile that for instance says "Map Data not available for this area". ...

Handle the bing layers InitializeFailed event in your code and look what the myBingLayer.InitializationFailure property is telling you. ... View more

yes this is possible, but you need to wait for the Initialized event to fire before you do any "editing". ... View more

How can you request data using querytask/graphicslayer on a 9.3.x server in a projection that matches the basemaps' spatial reference if this is only defined as a wkt? Ie if you can get data from a 9.3.1 server that overlays correctly on your map, there must be a valid wkid for that map that you can use instead of the wkt. Either that, or you are mixing spatial references which could lead to some major accuracy issues. On a side note my experience is that projection on the fly is not really a big overhead at all. Most of the performance issues is usually from pulling shapes out of the database and rendering it to the image. If you have issues with performance this is really stuff you should be looking at instead (msd and/or caching will also help way more than what you loose on reprojection) ... View more

I usually define a selection state on the graphic, and when I perform a roll-over, set the graphic to selected, and unselected when I roll out again. Here's an example of this in action: http://resources.esri.com/arcgisserver/apis/silverlight/index.cfm?fa=codeGalleryDetails&scriptID=16102 (note that this is a very old sample and was written with v1.0beta, so a couple things might have changed, but the idea is the same) ...

The draw object also has an event that gets fired each time a vertex is added that you can use instead. ... View more

The Editor actually does what you are doing (although it used the Draw object, and it's the draw object that prevents navigation), so it is possible to do with intercepting events. I'm not sure how you would NOT disable map navigation while drawing on the map. Doing both at same time would be really confusing. Either you draw on the map, or you navigate the map. ... View more

I would suggest you ask in the REST Server forums where there are a lot more people who knows the server: http://forums.arcgis.com/forums/11-ArcGIS-Server-REST-API ... View more

We have identified the issue as a problem with Silverlight. However we have a workaround in place, and you should see vastly improved performance (10-20x) in the next release. Sorry for the inconvenience, and thanks for reporting this. For what its worth, Bing would also be similarly affected if you tried to do the same amount of functionality that our graphics does 🙂 ...
