can anybody help me to solve my issue permanent? Sorry I can't hlp on this matter. It's definitively not a Silverlight issue and I don't figure out how a service can switch from non secured to secured without action at server side. But you might have more chance to get an answer by posting your question on the server forum. Good Luck. ... View more

You have to set EnableDynamicLayers to true in order to be able to change the renderer or the labelling of local dynamic layers. <esri:ArcGISLocalDynamicMapServiceLayer Path="States.mpk" EnableDynamicLayers="True"> ..... Then make sure that the field NAME1 does exist: <esri:LabelClass LabelExpression="[NAME1]" > else the labelling won't work. For testing purpose, you can set an hardcoded expression not depending on field names such as: <esri:LabelClass LabelExpression="&quot;TEST&quot;" > ... View more

Yes, the exact same exception Strange. CreateRenderSurface is not supposed to be called when UseAcceleratedDisplay is false. How to you set UseAcceleratedDisplay? May be a binding that would kick in too late might explain the issue. Note: it's also worth trying without setting UseAcceleratedDisplay since the default value is false. ... View more

Hi, thanks for replying. I have followed the sample you gave me, and it works fine. But now i have lost functionality of the legend when check/uncheck the group layer check box which the feature layer became its child after the replacement. Should i handle it myself now? or there is something else i could do? Yes. That's the drawback, The feature layer is artificially placed in the dynamic layer legend hierarchy but is not following the same rules concerning the scale range and the visibility. For the scale range, you can define the feature layer with the same scale range as the sublayer it replaces. That should solve the scale range issue. For the visibility, you could by code link the feature layer visibility to the visibility of the dynamic layer and the visibility of the group layer. For example after making _groupLayerItem a member variable, define a method UpdateFeatureLayerVisibility as void UpdateFeatureLayerVisibility() {     if (_featureLayerItem != null && _groupLayerItem != null)         _featureLayerItem.IsEnabled = _groupLayerItem.Layer.Visible && _groupLayerItem.IsEnabled; } and call this method when the layer or group layer visibility changes: if (subLayerItem != _featureLayerItem) // else replacement already done {     dynamicLayerItem.Layer.PropertyChanged += (s, evt) =>     {         if (evt.PropertyName == "Visible")             UpdateFeatureLayerVisibility();     };     ((ISublayerVisibilitySupport)dynamicLayerItem.Layer).VisibilityChanged += (s, evt) => UpdateFeatureLayerVisibility(); ...... That being said, it will become more complex if you want to manage multi group layer levels and multiple feature layers so I may not recommend this approach, but if this can help for a selective and specific need.... ...

Your binding to the Map is wrong. Instead of: Map="{Binding ElementName=Map,Path=Layers.[CASABLANCALAYER].Layers}" try Map="{Binding ElementName=Map}" ... View more

It might be a problem with the Silverlight URL restrictions, Please check if you miss something to help you out from here http://msdn.microsoft.com/en-us/library/cc189008%28v=vs.95%29.aspx For example Image doesn't allow cross scheme access. ... View more

The maptip is not in the same namespace as the main window so you can't use the element name this way. Instead use the datacontext which is set with the dictionary of attributes. Something like: var button = sender as Button; var attributes = button.DataContext as IDictionary<string, object>; var currentName = attributes["Name"].ToString(); .... ... View more

The feature layers are supposed to show up in the legend as others layers. The interactive SDK Legend Sample demonstrates an example of feature layer in the legend ('Points of Interest'). Might be you redefined the legend style in your application that would overwrite the default. Check in app.xaml. Else could you provide a repro case with public services? Thanks ... View more

But Pls note recently only It is asking for Login. Till two weeks back when I access the service ,It was not ask for login. I didnt made any changes in the ESRI services Or Not did any setting changes in ESRI 10.01 Server.Only Windows update doing in the server system. If the secured service is not expected, you should contact your server administrator to come back to a non secured service. Anyway the issue is coming from the server side and not from the client side and SL. ... View more

I don't get where is the 'ArcGIS API fo Silverlight' involved in this issue? I can only recommend the MSDN documentation about SL trusted applications and their restrictions. ... View more
