What I've done is set the DrawMode to Point and then put the text the user types in a textbox at that point - code snippet below.  Might work for other DrawMode geometry types too, just haven't tried it.  void Draw_DrawComplete(object sender, DrawEventArgs e)         {             GraphicsLayer gl = _Map.Layers[_glayer] as GraphicsLayer;             if (_bolText)  //if user selected text from drawing options             {                 (_symbol as TextSymbol).Text = txtText.Text;                 txtText.Text = string.Empty;                 spText.Visibility = Visibility.Collapsed;             }             Graphic g = new Graphic()             {                 Geometry = e.Geometry,                 Symbol = _symbol             };             gl.Graphics.Add(g);             gl.Refresh();             _Draw.IsEnabled = false;             _Draw.DrawMode = DrawMode.None;         } ...

Thank you for the information Dominique.  I'm still using 2.3 at this time - we're just starting to install & test 10.1 but may move the API to v3.0 to get this working.  In the meantime, it looks like I can hit www.arcgis.com/sharing/content/items/<Item ID>/data?f=json to grab what I need and update the legend control. Thanks again, Terry edit - here's the code to implement my idea above                        webMap = new Document();                         webMap.GetMapCompleted += (s, a) =>                         {                             if (a.Error == null)                             {                                 MyMap.Extent = a.Map.Extent;                                 WebClient web = new WebClient();                                 web.OpenReadCompleted += (send, arg) =>                                 {                                     JsonObject jsObj = (JsonObject)JsonObject.Load(arg.Result);                                     if (jsObj.ContainsKey("error"))                                     {                                         return;                                     }                                     if (jsObj.ContainsKey("operationalLayers"))                                     {                                         JsonArray layers = (JsonArray)jsObj["operationalLayers"];                                         foreach (JsonObject jOb in layers)                                         {                                             if (jOb.ContainsKey("itemId"))                                             {                                                 try                                                 {                                                     MyMap.Layers[jOb["itemId"]].ID = jOb["title"];                                                 }                                                 catch { }                                             }                                             else if (jOb.ContainsKey("id"))                                             {                                                 try                                                 {                                                     MyMap.Layers[jOb["id"]].ID = jOb["title"];                                                 }                                                 catch { }                                             }                                         }                                     }                                     if (jsObj.ContainsKey("baseMap"))                                      {                                         JsonObject jOb = (JsonObject)jsObj["baseMap"];                                         if (jOb.ContainsKey("baseMapLayers"))                                         {                                                                                        try                                             {                                                 MyMap.Layers[jOb["baseMapLayers"][0]["id"]].ID = jOb["title"];                                             }                                             catch { }                                         }                                     }                                 };                                 web.OpenReadAsync(new Uri("http://www.arcgis.com/sharing/content/items/" + mapservice.MapServiceName + "/data?f=json"));                                 LayerCollection layerCollection = new LayerCollection();                                 foreach (Layer lyr in a.Map.Layers)                                 {                                     layerCollection.Add(lyr);                                     lyr.InitializationFailed += Layer_InitializationFailed;                                 }                                 a.Map.Layers.Clear();                                 MyMap.Layers = layerCollection; ...

Hi Ravi, Yes, I manually cleared the cache while testing this.  I also have the cache set to clear daily and I still don't see the data exclusion symbol.  The Map Service is coming from a MSD file, would that make a difference vs. a MXD powered service? Thanks again, Terry ... View more

Thanks for the suggestion Dominique.  I've checked and all debug options are turned on in the web project.  I've also tried various combinations of the debug options (tools -> options -> debug node) suggested on StackOverflow and other forums to no avail.... I installed SP1 and rebooted; I ran devenv /ResetSettings from the command line I've even tried pulling the last good version from MS SourceSafe from when I last touched the solution and still get the same behavior. -update- I reinstalled VS2010 and still see the same behavior.  Created a new SL project with no Esri references and get the same problem.  I pulled my mapping SL project from SourceSafe onto another machine (WinXP) and I can debug normally.  Something on my Win7 box has changed in the last month and is not allowing for SL debugging. Any other ideas?  Thanks, Terry ... View more

I just hit this problem yesterday too.  I can use F10 (step over) and F11 (step through) in other projects, such as a C# console app that converts an XLS to a featureclass but not in my Silverlight project. I know this is kind of beyond the scope of Esri, but any help would be appreciated. Running Win7 64bit, VS 2010 (installing SP1 now), Silverlight API 2.3, debugging in IE9 Thanks, TG ... View more

Hello, I think you have 2 problems here - 1. I think your logic is off in your code.  You're checking to see if the map is in Geographic (srid = 4326) and if it is, creating a new point with the same coords as the map point but defining the new points projection as UTM Zone 40 (srid =32640).  I think you want to check if your map is not in geographic, e.g (mapa.SpatialReference.WKID != 4326) 2.  In the project complete from the geometry service, if you're projecting the point to 4326, the units are in decimal degrees.  It's easy to conver that to Degree Minutes Seconds with some quick math... A quick Google search yielded this -http://geography.about.com/library/howto/htdegrees.htm  for example.  Hope this helps, Terry ... View more

Might not be exactly what you're looking for but you can call methods in the Silverlight classes from JavaScript, if you flag the class with the ScriptableType() attribute & flag the method(s) you want exposed to JavaScript with the ScriptableMethod() attribute.  Silverlight objects can also call JS functions in your webpage via the ScriptObject class. calling JS function from within SL- // in SL code behind -             ScriptObject js = (ScriptObject)HtmlPage.Window.GetProperty("some_js_function");             js.InvokeSelf("called from SL"); //Javascript in page -             function some_js_function(arg) {                 alert(arg.toString());             } Call SL method from JavaScript // JS function in the page, called by a button's onclick             function Call_SL_Method(arg) {                 var sl = document.getElementById("silverlightControl");                 sl.content.Page.SetUserName(arg);             } //in Silverlight Code Behind, decorate the class & method to expose to JS     [ScriptableType()]     public partial class MainPage : UserControl     {         [ScriptableMember()]         public void SetUserName(string name)         {             //txtName is a textblock to hold user name             txtName.Text = name;         }         public MainPage()         {             InitializeComponent();             //register the class with the HtmlPage             HtmlPage.RegisterScriptableObject("Page", this);             ....          } ...

Chris, You don't need ArcGIS Server installed to use the Silverlight API - you can use your WMS services and/or map services from other providers, such as ESRI's ArcGIS online. "Is the API free" - well, in general I'd say yes, but encourage you to read the License Agreement when you download it to make sure you intended use meets their terms. ... View more

Chris, The ESRI silverlight toolkit contains a class for displaying WMS services - see http://help.arcgis.com/en/webapi/silverlight/samples/start.htm#WmsLayerSimple for a sample and CodePlex to download the toolkit - http://esrisilverlight.codeplex.com/documentation.  I've never looked at the source code for the toolkit but I'm guessing it handles all of the GetMap requests for you.. One thing to note though is that the WMSLayer class in the toolkit does not support the ability to Identify (GetFeatureInfo in WMS terms) on a WMS layer.  I implemented my own WCF service to handle this which was pretty straight forward - - Pass the info (e.g. map extent, spatial reference, layers to query, etc...) you need to perfrom a WMS GetFeatureInfo request** from the Silverlight client to the service; - in the WCF service, build a URL containing the GetFeatureInfo request and use WebClient.OpenRead() to stream the results. -pass back to the client the results and handle as needed. **Note there are differences between WMS versions on the required parameters, their names, and for the BBox, the order of the parameters.  I found a nice summary table between versions 1.1 and 1.3 somewhere on either the OGC or ESRI website, but don't recall where. Hope this helps, Terry ... View more

Hi Percy, On that server, when I upgraded from ArcGIS Server 9.3.1 to 10.0, the issue described above stopped happening.  Never did find the real reason for the behavior though, sorry. ... View more
