Initialize is an asynchronous operation, which means you have to do the code in your Initialized event handler.    ArcGISDynamicMapServiceLayer layer = new ArcGISDynamicMapServiceLayer() { Url = "http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StateCityHighway_USA/MapServer" };    layer.Initialized += (a, b) =>     {      if (layer.IsInitialized && layer.InitializationFailure == null)       map1.Layers.Insert(1, layer);     };       layer.Initialize(); Is equivalent to:    ArcGISDynamicMapServiceLayer layer = new ArcGISDynamicMapServiceLayer() { Url = "http://sampleserver1.arcgisonline.com/ArcGIS/rest/services/Specialty/ESRI_StateCityHighway_USA/MapServer" };    layer.Initialized += new EventHandler<EventArgs>(layer_Initialized);      layer.Initialize();   }    void layer_Initialized(object sender, EventArgs e)   {    var layer = sender as Layer;    if (layer.IsInitialized && layer.InitializationFailure == null)     map1.Layers.Insert(1, layer);   } ...

1.I am adding lot of picturemarker features on map in button clik based on some condition.Now i can see some of the features after dragging the map only.How can i see all feature collection without dragging? After your graphics are added to GraphicsLayer, you can call ZoomTo, provided your map and layer have the same SpatialReference. MyMap.ZoomTo(graphicsLayer.FullExtent) 2.How can i clear all the existing features(picturemarker) in button click? You can use either one of these two: graphicsLayer.ClearGraphics() //or //graphicsLayer.Graphics.Clear() 3.How can i link each picturemarker with a straight line with arrow. You can add another GraphicsLayer that will contain Polyline and use Renderer with LineSymbol. After all point graphics (picturemarkers) are added to the other GraphicsLayer, use their geometry as MapPoint in your Polyline.Path.PointCollection I just used C# to VB converter so I'm not quite sure this works. The idea is you will clone your point graphic geometry add make that as a vertex in your polyline. lineGraphicsLayer.Renderer = New SimpleRenderer() With { _  Key .Symbol = New SimpleLineSymbol() With { _   Key .Color = New System.Windows.Media.SolidColorBrush(System.Windows.Media.Colors.Red), _   Key .Width = 3, _   Key .Style = SimpleLineSymbol.LineStyle.Solid _  } _ } Dim polyline = New Polyline() Dim pc = New PointCollection() For Each g As var In pointGraphicsLayer.Graphics  Dim mp = TryCast(Geometry.Clone(TryCast(g.Geometry, MapPoint)), MapPoint)  pc.Add(mp) Next polyline.Paths.Add(pc) lineGraphicsLayer.Graphics.Add(New Graphic() With { _  Key .Geometry = polyline _ }) 4.How can i set a maptip on eachpicture marker in buttonclick event? Like infowindow showing in featureservice popup sample.All sample maptip code is adding from the tables . I need to add some textbox vaule as maptip. You can use VB code from this SDK sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#InfoWindowSimple. You will need to update DataTemplate in XAML and if you want this to change your graphic.Attribute, you can change Binding statement Mode to TwoWay.         <DataTemplate x:Key="MyFeatureLayerInfoWindowTemplate">                 <TextBoxText="{Binding [STATE_NAME]}" Foreground="Black" FontSize="12" />             </DataTemplate> ...
