Hi Ryan, The SL framework is not using the CLR accessor, so it's normal that your break points in get/set are never used. What you could test is to define a callback on the property changed and try to put a break point at this level. Something like:         //Members - Dependency Properties         protected static readonly DependencyProperty dependencyPropertyMap = DependencyProperty.Register("Map", typeof(Map), typeof(DataToolbar), new PropertyMetadata(null, OnMapChanged)); private static void OnMapChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { // put a break point here }         //Properties         public Map Map         {             get { return (Map)GetValue(dependencyPropertyMap); }             set { SetValue(dependencyPropertyMap, value); }         } Hopefully this will help. ...

I did some additional tests and I was able to reproduce the issue when the DP is initialized with a binding. Is it your case? In this case, the DP is initialized after the Loaded event (if the control is visible), and so if the loaded event put the visibility to collapsed, the DP is not initialized. This behavior doesn't look tie to the Window Panel but more general to the Loaded event with Silverlight. I found an article (http://bryantlikes.com/FakingTheInitializedEventInSilverlight.aspx) which is suggesting to use the dispatcher in the constructor. If we change the visibility this way, the DP are initialized (in the cases I tested...) public MainPage() { InitializeComponent(); Dispatcher.BeginInvoke(Initialized); } private void Initialized() { MyControl.Visibility = Visibility.Collapsed; } Note that another workaround could be you to change the Opacity instead of the Visibility. Keep your control visible but with an opacity of 0. So the DP are initialized and when your control is ready, you can set the opacity to 1.0. ... View more

You have to deal with the order of the layers in the LayerCollection Map.Layers. I have no code to provide, but as a LayerCollection is also implementing ICollection and IList, it should be easy to change the order. ... View more

In the example, the datacontext of each item is the layer itself (it's why we can display the name, change the opacity....). So if you add a 'Delete' button, you have to write a code like: private void ButtonDelete_Click(object sender, System.Windows.RoutedEventArgs e) { FrameworkElement element = sender as FrameworkElement; this.MyMap.Layers.Remove(element.DataContext as Layer); } The layer will be removed from the map and the button/checkbox/slider will be removed automatically as well (thanks to the SL/WPF binding). Concerning your question about the layer removal through XAML, I don't think you can do that out of the box. ... View more

Something simple like: double ratio = 200/200.5;     p2.X = p1.X + ratio * (p2.X-p1.X); p2.Y = p1.Y + ratio * (p2.Y-p1.Y); or do you need to deal with geodesic precision? ... View more

In this case, you can no more take advantage of the existing collection 'QueryTask.LastResults.Features'. You have to manage yourself a collection of graphics. When you get the result of a query, depending on your need, you can append/replace/combine/clear the collection. ... View more

As your control is not visible, it's not loaded. You might try by making it visible and by collapsing it when loaded. Example in XAML:             <i:Interaction.Triggers>                 <i:EventTrigger EventName="Loaded">                     <ei:ChangePropertyAction PropertyName="Visibility">                         <ei:ChangePropertyAction.Value>                             <Visibility>Collapsed</Visibility>                         </ei:ChangePropertyAction.Value>                     </ei:ChangePropertyAction>                 </i:EventTrigger>             </i:Interaction.Triggers> ...

Which version of API are you working with? I forgot to mention that LayerInfo property was only existing from version 2.0. Links to documentation:   LayerInfo property : http://help.arcgis.com/en/webapi/silverlight/apiref/topic316.html   FeatureLayerInfo members : http://help.arcgis.com/en/webapi/silverlight/apiref/topic342.html If you are using the version 2.0 and don't get any description for your feature layer, check that your service is giving such information. Example of service giving a description and a copyright : http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/0?f=pjson ... View more

The extension method 'ESRI.ArcGIS.Client.Bing.Transform.GeographicToWebMercator(this ESRI.ArcGIS.Client.Geometry.MapPoint)' should be helpful. /Dominique ... View more

For a featureLayer, Description and CopyrightText are given by the property layerInfo. A tooltip like:    <ToolTipService.ToolTip>         <StackPanel MaxWidth="400">             <TextBlock FontWeight="Bold" Text="{Binding CopyrightText}" TextWrapping="Wrap" />             <TextBlock FontWeight="Bold" Text="{Binding LayerInfo.CopyrightText}" TextWrapping="Wrap" />             <TextBlock Text="{Binding Description}" TextWrapping="Wrap" />             <TextBlock Text="{Binding LayerInfo.Description}" TextWrapping="Wrap" />         </StackPanel>     </ToolTipService.ToolTip> should work in this case. /Dominique ...

Get the rings of the polygon, each ring is a collection of point. For example, to get the points of the first ring of your polygon, you can use : ESRI.ArcGIS.Client.Geometry.PointCollection points = myPolygon.Rings[0]; /Dominique ... View more

You are getting the same error than if your feature layer URL was incorrect. Verify what you get if you execute a query on your feature layer URL. With the sample, you get this : http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Demographics/ESRI_Census_USA/MapServer/0?f=pjson (pjson =  format pretty json to be more readable). /Dominique ...
