I tweaked the FeatureLayerSimple sample to return only one feature (Where="CITY_NAME='Spokane'") and your initial code is still working. Though the code you just posted is not working  since the FullExtent size is zero (the size of one point geometry is zero : that's normal). So I suggest that in this case you introduce a minimum size (as you did in your first post with 'coordOffset') Yup your right I changed the value to 0.01 and it worked fine.. thnx a bunch 🙂 ...

I tested your code with the FeatureLayerSimple interactive sample and it looks working (despite there is only one feature layer). Could you give more info on how to reproduce the issue? Thanks The code does work with a feature layer when the count is greater than 1 what I am talking is when the feature layer count is 1.. i.e only one feature.... for example in a graphics layer also when the graphic count is 1 the graphicsLayer.FullExtent.Width and graphicsLayer.FullExtent.Height is 0.0 but when the graphics count is greater than 2 it has values FeatureSet featureSet = e.FeatureSet;                 if (featureSet != null && featureSet.Features.Count > 0)                 {                     // If an item has been selected                                GraphicsLayer graphicsLayer = mainPage.map.Layers["tempGraphicLayer"] as GraphicsLayer;                     if (graphicsLayer == null)                     {                         graphicsLayer = new GraphicsLayer();                         graphicsLayer.ID = "tempGraphicLayer";                         mainPage.map.Layers.Add(graphicsLayer);                     }                     Graphic selectedFeature = null;                     for (int i = 0; i < featureSet.Features.Count; i++)                     {                         // Show selected feature attributes in DataGrid                         selectedFeature = featureSet.Features;                         selectedFeature.Symbol = LayoutRoot.Resources["MarkerSymbol"] as ESRI.ArcGIS.Client.Symbols.Symbol;                         graphicsLayer.Graphics.Add(selectedFeature);                     }                     graphicsLayer.Opacity = 0.7;                     double expandPercentage = 30;                     double widthExpand = graphicsLayer.FullExtent.Width * (expandPercentage / 100);                     double heightExpand = graphicsLayer.FullExtent.Height * (expandPercentage / 100);                     if (graphicsLayer != null)                     {                         ESRI.ArcGIS.Client.Geometry.Envelope displayExtent = new ESRI.ArcGIS.Client.Geometry.Envelope(                         graphicsLayer.FullExtent.XMin - (widthExpand / 2),                         graphicsLayer.FullExtent.YMin - (heightExpand / 2),                         graphicsLayer.FullExtent.XMax + (widthExpand / 2),                         graphicsLayer.FullExtent.YMax + (heightExpand / 2));                         mainPage.map.ZoomTo(displayExtent);                         KeyValuePair<int, string> str = (KeyValuePair<int, string>)lstChainage.SelectedItem;                         mainPage.lblcustomStatusBar.Content = str.Value + " located";                         mainPage.lblcustomStatusBar.Foreground = new SolidColorBrush(Colors.Blue);                     }                 } ...

One way is you to use the LayerItemViewModel  'Tag' property to store your length. You can initialize the 'Tag' property by code on event legend 'Refreshed' and then just display it with a Binding to Tag. For more complex scenarios, you can also set the Tag property to a dictionary and use a binding such as {Binding Tag[Length]}   (by supposing your dictionary has a 'Length' entry) Thank you tag worked <sdk:Label x:Name="label1" Content="{Binding Tag}" MinWidth="40"/>             dicSurfaceLength = e.Result;             foreach (LegendItemViewModel legendItems in mainPage.CustomLegend.LayerItems[0].LegendItems)             {                 legendItems.Tag = e.Result[legendItems.Label];             } ...

The legend control worked well ESRI.ArcGIS.Client.Toolkit.Legend.RefreshedEventArgs e) {   var fLayer = e.LayerItem.Layer as FeatureLayer;   if (fLayer != null && fLayer.ID == "MyFeatureLayer2" && e.LayerItem.LegendItems != null)   {     var toRemove = e.LayerItem.LegendItems.Where(item => item.Label != "7").ToArray(); // Warning : may be a coded value instead of just '7'. Depending on your model     foreach (var item in toRemove)       e.LayerItem.LegendItems.Remove(item);   } } but I display the Label with its symbol.. I want to add the length of the polyline(road) in KMs which will be queryed from the database.. is this possible .. ... View more

The problem is coming from your ItemsSource binding: With this binding you will get all renderer infos whatever it's used or not. One option is you to implement by code your own enumeration that returns only the symbols used in the layer. Hi, Thanks you for your reply I have been breaking my head over this trying to remove items from the Legend control.. Can you please throw in a little bit of code that would help me overcome this issue ... View more
