If _candidateGraphicsLayer.Graphics.Count > index condition fails, then index does not match your GraphicsCount. You have to debug through your code to know if _candidateGraphicsLayer.Graphics.Add() is hit and what value index is when it tries to access _candidateGraphicsLayer.Graphics. ... View more

Yes this code should replace your FeatureDataGrid_SelectionChange event handler. This is how you can get the graphic from FDG.row. Once you have the graphic, you can set AttachmentEditor.GraphicSource property. ... View more

Thank you for sharing the sample. Since v2.3 introduced Auto-Projection, we cannot use GraphicsLayer.SpatialReference. You must set Map.SpatialReference by setting its Extent.SpatialReference: <esri:Map WrapAround="True" x:Name="MyMap" Grid.Column="0" Grid.Row="1" >    <esri:Map.Extent>      <esri:Envelope>       <esri:Envelope.SpatialReference>        <esri:SpatialReference WKID="4326"/>       </esri:Envelope.SpatialReference>      </esri:Envelope>    </esri:Map.Extent>     <esri:GraphicsLayer >                 <esri:GraphicsLayer.Renderer>                     <esri:SimpleRenderer Symbol="{StaticResource DefaultLineSymbol}"/>                 </esri:GraphicsLayer.Renderer>                 <esri:GraphicsLayer.Graphics >                     <esri:Graphic>                         <Geometry:Polyline >                             <Geometry:Polyline.Paths>                                 <Geometry:PointCollection>                                     <Geometry:MapPoint X="0" Y="51.399" />                                     <Geometry:MapPoint X="2.637" Y="48.865" />                                     <Geometry:MapPoint X="12.568" Y="41.706" />                                     <Geometry:MapPoint X="13.447" Y="52.483" />                                     <Geometry:MapPoint X="21.357" Y="52.160" />                                     <Geometry:MapPoint X="30.322" Y="59.845" />                                 </Geometry:PointCollection>                                   </Geometry:Polyline.Paths>        <esri:Polyline.SpatialReference>         <esri:SpatialReference WKID="4326"/>        </esri:Polyline.SpatialReference>                         </Geometry:Polyline>                     </esri:Graphic>                 </esri:GraphicsLayer.Graphics>             </esri:GraphicsLayer>             <!--<esri:ArcGISTiledMapServiceLayer ID="MyLayer"                 Url="http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer" />-->         </esri:Map> In addition, I've added this in code-behind so you can zoom to GraphicsLayer.FullExtent    MyMap.Layers.LayersInitialized += (s, e) =>     {      MyMap.ZoomTo(MyMap.Layers[0].FullExtent);     }; ...

Here's some description on the RouteParameters: http://help.arcgis.com/en/webapi/wpf/apiref/ESRI.ArcGIS.Client~ESRI.ArcGIS.Client.Tasks.RouteParameters.html If you look at Fiddler response when using this SDK sample http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#Routing, you will see that Total_Time and Shape_Length are returned with RouteDirections=False.

Can you attach a sample? I tried to add a GraphicsLayer to this SDK sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#UtilityActions but was not able to get the error even with the ArcGISTiledMapServiceLayer Visible=True. ... View more

You can use just one GraphicsLayer to label your features. If the graphics are of the same geometry, it is okay that they are added to the same layer. You can even set GraphicsLayer.Renderer to SimpleRenderer with TextSymbol that points to an attribute, this way you don't need to create TextSymbol instance every time. ... View more

This seem related thread: forums.arcgis.com/threads/8680-FeatureLayer-and-SpatialRelationship-for-selection-geometry The RelationshipResult can be filtered by geometry from the client API using FindGraphicsInHostCoordinates() or Intersects().

The code-snippet I posted is for editing. If the graphic does not exist yet and you want to intercept the draw, you can use Draw.VertexAdded event, Draw.UndoLastVertex(), calculate new MapPoint, and Draw.AddVertex(newPoint). After the vertex was removed (UndoLastVertex), endpoint will be the start point from which you need to calculate the next point given the desired distance. Once you have this new point, you can AddVertex(newPoint). PointCollection pnts = (_graphic.Geometry as Polyline).Paths[0]; MapPoint endPoint = pnts[pnts.Count - 1]; ... View more

I'm not sure if this works for you but you can try updating this SDK sample: http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#EditToolsGeometry VertexAdded is one of GeometryEdit action, you can compare the distance between vertices then and if the shortest distance is still outside the max distance, you can Undo the last edit.         private void EditGeometry_GeometryEdit(object sender, EditGeometry.GeometryEditEventArgs e)         {    if (e.Action == EditGeometry.Action.VertexAdded)    {     var graphic = e.Graphic as Graphic;     var polyline = graphic.Geometry as Polyline;     var distance = double.NaN;     var vertex = e.NewItems[0] as MapPoint;     foreach (var p in polyline.Paths[0])     {      if (!double.IsNaN(distance)) break;      var d = Math.Sqrt(Math.Pow(Math.Abs(vertex.X - p.X), 2) + Math.Pow(Math.Abs(vertex.Y - p.Y), 2));      if (double.IsNaN(distance) || d < distance)       distance = d;       }     if (distance > maxDistance)      editGeometry.UndoLastEdit();    } ...

If you know the new geometry (X,Y), you can just set graphic.Geometry = new MapPoint(X, Y, MyMap.SpatialReference); You don't need to handle MouseMove. ... View more

Yes this is correct, FeatureDataForm.IsValid property is set when an error is returned from updating a field and/or clicking apply. FeatureDataForm.EditEnded event is raised only if IsValid and updates to the attributes were commited successfully. ... View more
