The API support for touch and gestures was added in 2.1 http://help.arcgis.com/en/webapi/silverlight/2.1/help/index.html#/What_s_new_in_2_1/016600000025000000/ so yes v2.3 still supports touch 🙂 Thank you Jennifer! ... View more

Hello Jeff, The problem is only when I zooming, but not always, displacement sometimes appears, sometimes not appears. When zoom ends, the layer is in correct place. Thanks for the response. Pau Pérez Conselleria de Infraestructuras, Territorio y Medio Ambiente http://cma.gva.es http://cartoweb.cma.gva.es Yes! this is issue is present in JS API and I have noted this too, when panning the map. After the pan operation completes the map pans but the layer gets shifted. ... View more

That's a bug. We'll try to get it fixed in a future version. Thanks for reproting that. Thank you Dominique 🙂 ... View more

I think InfoWindow is open but is not visible until you pan the map. Try the SDK sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#InfoWindowSimple. Pan the map to where the feature is not fully visible and click on it, InfoWindow is open but is not within view until you pan the map. I had tried all the possible ways and also the infowindowsimple sample which does not help. I pan the map and a already open infowindow disappears near, atleast half a inch away from the top left and (atleast half a inch away from map edge) bottom right corners of the map. ... View more

When you were using mouse event on the FeatureLayer, you had direct access to the graphic in the GraphicMouseButtonEventArgs. If you moved your mouse event to the symbol control template, you need to use screen point and FindGraphicsInHostCoordinates  FeatureLayer featureLayer = MyMap.Layers["MyFeatureLayer"] as FeatureLayer; System.Windows.Point screenPnt = e.GetPosition(MyMap); // Account for difference between Map and application origin GeneralTransform generalTransform = MyMap.TransformToVisual(Application.Current.RootVisual); System.Windows.Point transformScreenPnt = generalTransform.Transform(screenPnt); IEnumerable<Graphic> selected =                 featureLayer.FindGraphicsInHostCoordinates(transformScreenPnt); foreach (Graphic g in selected) { //this must be your graphic of interest } Thank you Jennifer, the code and guidelines given by you, I tried them too but still I have the same behavior from the map that I dont see the info window only if the graphic is on the top left corner or bottom right corner of the map. If at the same moment I pan the map to center the info window shows but if I pan the map back to the earlier location where the graphic comes to corner of the map, the info window disappears again. it is due to the map rotation only.. please let me know your views... Thanks again 🙂 ... View more

I get an error with the   .SelectedGraphics; It says that 'System.Windows.Controls.Datagrid' does not have a SelectedGraphics.  Any suggestions? Change your datagrid in xaml to <esri:FeatureDataGrid (instead of using windows controls datagrid)... ... View more

Can anyone share a working code for this? I already have my mouse coordinates showing in xy, but want to give the user an option to change to lat/lon on the fly.

hi! My experience about some error of first access are solved by checking the option: "Periodically check and repair data connections for idle instances" with 30 minutes. What I have found is that my db administrator stop the database for backup issue and after that the service don't work. With this option all is ok. Note: the service is for editing data. Service with read only data are oks. This is a issue present still after upgrading to SP2. Even after setting all services with the option "Periodically check and repair data connections for idle instances" with 30 minutes. Does not help if the server has been idle over night.. in the morning whoever is the first to access the SL API application is sure to get a splat ERROR white page.. even though I tried to handle the error from code by layer initialized event.. ...

Thank you jenniferdnery! I will try.

Your first atttempt with WebMercator. The WebMercator is a client side projection from "web mercator" to Geographic (4326 ) and back. You need to use the GeometryService projection and project 32640 to 4326. Looking at your geometry service projection it appears you are projecting from 32640 to 32640 which is the same thing as you started with. all you should need to do is reaplace the out spatial reference with 4326.
