Saving Graphics to map using WPF, C# and ArcGIS for Server?

Question

I have everything working just like I need it to, but when I add a new graphic to the map it does not save it. So I will add it, close the application, and when I reopen it the graphic is gone. I have AutoSave set to true on both of my feature maps. If anyone knows what my problem is or possible solutions I would really appreciate the help. I am using WPF and C#. I also have my map published to a map server. I don't quite understand the arcGIS for Server though. I have only been using arcGIS for a couple of weeks so bare with me on this one haha.

Below is some of my code. If you need me to clear up anything just leave me a comment.

C# Code Example of when I add something:

private void MyMap_MouseClick(object sender, Map.MouseEventArgs e)
 {
 if (blnAddInformationClicked)
 { 
 locatorTask.LocationToAddressCompleted += LocatorTask_LocationToAddressCompleted;
 locatorTask.Failed += LocatorTask_Failed;
 double tolerance = 30;
 locatorTask.LocationToAddressAsync(e.MapPoint, tolerance, e.MapPoint);
 InstructionGrid.Visibility = Visibility.Collapsed;
 PortalGrid.IsEnabled = true;
 }
 }
 private void LocatorTask_LocationToAddressCompleted(object sender, AddressEventArgs args)
 {
 locatorTask.LocationToAddressCompleted -= LocatorTask_LocationToAddressCompleted;
 if (Information.ContainsKey(txtNumber.Text))
 {
 MessageBox.Show("This Object has already been added");
 PortalGrid.Visibility = Visibility.Visible;
 InformationGrid.Visibility = Visibility.Visible;
 return;
 }
 Address address = args.Address;
 Dictionary<string, object> attributes = address.Attributes;
 if (radWaterMeter.IsChecked == true)
 { 
 Graphic graphic = new Graphic()
 {
 Symbol = AddressLayout.Resources["WaterMeterRenderer"] as ESRI.ArcGIS.Client.Symbols.Symbol,
 Geometry = args.UserState as MapPoint
 };
 string address1 = attributes["Street"].ToString();
 string address2 = String.Format("{0}, {1} {2}", attributes["City"], attributes["State"], attributes["ZIP"]);
 string addressCombined = String.Format("{0},{1},{2},{3}", attributes["Street"].ToString(), attributes["City"], attributes["State"], attributes["ZIP"]); ;

 }

I have two different feature layers. There is a radio button there that determines which feature layer and graphic to use. The graphics/renderers are just .png files that are on my C: drive. I add the attributes to the graphics using a list and the information giving by the user. These attributes are then added to the maptip. The graphics are being added, but it does not save it to the map, so when I reopen the application the graphics that I added are not there anymore.

I have looked through all of the resources for arcGIS that I could find and there is nothing there that is helping me much. I feel as though the resources are lacking when it comes to beginners.

• Get Spatial: Thanks for adding the code detail. It might help if you detail the process you follow that adds these graphics to the map. Also a screenshot showing the graphics may help.
• JLott: I don't think I can add an image until I have a reputation of 15... But I did add a little more detail to the question.
• Mapperz: JLott your rep is now 16 - you can add images...

Answer 1

when you create the feature layer be aware that you set the properties

DisableClientCaching = true, AutoSave = false, Mode = FeatureLayer.QueryMode.Snapshot

then it will be save the edits with:

graphicsLayer.SaveEdits();

• JLott: Thank you :) I solved this a while ago using this. Completely forgot about the question.
• JLott: Can you do this with a feature layer?
• XtianGIS: I do that with an ArcGISLocalFeatureLayer that inherits from FeatureLayer
• JLott: I am about to ask another question. I have done this before not using a local feature layer and it worked... There has to be some little mistake that I am missing.
• XtianGIS: var localServiceMPK = new LocalFeatureService { Path = @"ArcGISPackages\MyPackage.mpk", MaxRecords = 100000 };

Answer 2

You can try serializing the graphic and then save it into isolated storage There are some good examples here and here.

• JLott: I really thought that there was a way to just save it to the map with the map server... I have a list set up that contains the attributes of each image... So I could probably have it loop through that like a database every time the app starts up.
