An "Update" re-executes the query for the layer and replaces exisiting features with new, so there is not a list of "just changed and/or added features". Therefore your only option is to iterate on all the features. However I doubt that should really be of much concern. Iterating 1000s of features can be done in a split second. I'm often doing complex LINQ joins and queries on large amounts of the data, and haven't seen any major performance hit (drawing a vast amount of features seems to be the bottleneck long before any other operation). ...

Since you are experiencing the same issue from the web interface, the issue is with your GP REST service and not the API. I suggest you ask in the REST and/or server forums: http://forums.arcgis.com/forums/11-ArcGIS-Server-REST-API ... View more

Since the first layer in  your map defines the spatial reference, I'm guessing that the ImageService's default spatial reference is not the same as the Bing Layer's. Tiled layers does not reproject so this wont work. You can force the spatial reference to match  Bing, and the two other layers should be capable of reprojecting to that projection (since they are both dynamic): (you might have to change the x/y values to work with this spatial reference) <esri:Map.Extent> <esri:Envelope XMin="2471999.70000267" YMin="521998.699899673" XMax="2490000.30005074" YMax="534000.300050735"> <esri:Envelope.SpatialReference><esri:SpatialReference WKID="102100" /><esri:Envelope.SpatialReference> </esri:Envelope> </esri:Map.Extent> ...

Could you share the layer metadata? Ie. go to the rest endpoint for the layer, add ?f=pjson to the URL, and paste the response here. (or even better if the service is public, share the URL) ... View more

It would be very helpful if you or someone post a sample on how to implement this? StackPanels are among the core basic UI Panels that you need to know when creating UI layouts in Silverlight and WPF (the only more important one is probably "Grid"). You should hopefully be familiar with Buttons already. <StackPanel Orientation="Horizontal" VerticalAlignment="Top" HorizontalAlignment="Center" Margin="10" Background="White">     <Button Click="Tool1_Click" Content="Tool1" />     <Button Click="Tool2_Click" Content="Tool2" />     <Button Click="Tool3_Click" Content="Tool3" /> </StackPanel> ...

The featurelayer expects a certain geometry type, so no you can't. However the base GraphicsLayer does support a mix of geometry types, but the symbol for each graphic must match the geometry type of the geometry (ie fillsymbol for polygons, linesymbols for polylines, markersymbols for points/multipoints). You could create a custom IRenderer that returns the right symbol type based on the geometry. You can still use the QueryTask to populate the graphicslayer against your "mixed table" from MapIt. ...

What version are you using? What are you using to draw and edit the feature? Does your service have a renderer defined without a default symbol, and the graphic you are adding doesn't have an attribute that matches any of the symbols defined in the renderer? What happens if you explicitly override the renderer with your own instead of using what is coming from the server? ... View more
