Hi, I am working on the measurement widget, and it seems that the out of box 'esri/dijit/Measurement' widget is always based on Web-Mercator projection. This makes the measurement result not as accurate as local projection if I understand correctly. Is there a way to use local projection to do the measurement by using this widget? Or I must build a fresh new widget from scratch by myself if I want to get accurate measurement result? Thanks, Wei ... View more

Hi, I have a layer in the MXD which has a related table, and I want to retrieve this related table info from the Identify and Search tool. Is there any way to do it? Thanks, Wei ... View more

Hi, I am new to JavaScript and ESRI JavaScript API. I am trying to enable the IntelliSense for the ESRI modules by using AMD, but it seems doesn't work. I have put the "jsapi_vsdoc12_v38.js" file in the VS solution, and reference with " <script type="text/javascript" src="Scripts/jsapi_vsdoc12_v38.js"></script>". But it seems that it doesn't work in the AMD. Is there a way I can enable it? Without IntelliSense, it will be too hard to coding. Thanks, Wei ... View more

Hi, I have some point graphics in one graphicLayer on the map and I want to move their positions to the new places every 5 seconds based on some criteria. Also on the map, these point graphics' movement can be visualized dynamically. How should I do that? It seems the map won't update until the graphics' last movement were finished. Should I create a new thread to fulfill this dynamic visualization or there is any other trick? Thanks, Wei ... View more

Hi, I try to use the Editor to edit my feature layer (already versioned). All the binding button (i.e., Add, Select, Delete) works. But all the edit changes doesn't affect the database at all (I checked the SDE database). Our web services are secured, and I use proxy. What I did is: 1) Add an Editor to the Grid resources: <esri:Editor x:Key="EditWellPadPolygon" Map="{Binding ElementName=MyMap}" LayerIDs="WetlandsDelinationArea" GeometryServiceUrl="http://ourwebsite/ArcGIS/rest/services/Geometry/GeometryServer"  EditCompleted="EditWellPadPolygon_EditCompleted"/> 2) Add the Feature layer to the map layers: <esri:FeatureLayer ID="WetlandsDelinationArea" ProxyUrl="../proxy.ashx" Url="http://ourwebsite.com/ArcGIS/rest/services/Project/EcologyMobileProjects/FeatureServer/6" AutoSave="True" ValidateEdits="True" DisableClientCaching="True" Mode="OnDemand" Opacity="0.8" Visible="False" OutFields="*" InitializationFailed="MapServices_InitializationFailed"/> 3) Add an editing panel with all the buttons: <StackPanel x:Name="editSP" Orientation="Vertical" VerticalAlignment="Stretch" DataContext="{StaticResource EditWellPadPolygon}">     <Button Command="{Binding Add}" Content="1. Add New Record" ToolTipService.ToolTip="" Margin="14,0,14,5"> <Button.CommandParameter> <sys:Int32>10101</sys:Int32> </Button.CommandParameter> </Button> <Grid > <Rectangle RadiusX="4" RadiusY="4" Margin="7,1,7,1" Stroke="Olive"></Rectangle> <StackPanel Orientation="Vertical" VerticalAlignment="Stretch"> <Button Command="{Binding Select}" CommandParameter="New" Content="2. Select a Record to Delete" Margin="14,8,14,8"/> <Button Command="{Binding ClearSelection}" Content="Clear Selection" Margin="28,2,14,8" Visibility="Collapsed"/> <Button Command="{Binding DeleteSelected}" Content="Delete Selected Record" Margin="28,2,14,8" Visibility="Collapsed"/> </StackPanel> </Grid> <Button Command="{Binding EditVertices}" Content="3. Change a Record Shape" Margin="14,5,14,5"/> </StackPanel> I don't think I need to code in the code behind. Correct me if I am wrong. To make sure this is not the problem, I added code in the code behind, but still doesn't work (I catched there is a Cancel action when I try to fire the add action. Don't know why.):         private void EditWellPadPolygon_EditCompleted(object sender, ESRI.ArcGIS.Client.Editor.EditEventArgs e)         {             switch (e.Action)             {                 case ESRI.ArcGIS.Client.Editor.EditAction.Add:                     editEditor.Add.Execute(null);                     break;                 case ESRI.ArcGIS.Client.Editor.EditAction.Save:                     editEditor.Save.Execute(null);                     break;                    case ESRI.ArcGIS.Client.Editor.EditAction.DeleteSelected:                     editEditor.DeleteSelected.Execute(null);                     break;                       }         } Many thanks for any help!
