Upon closer review seems the calls are not the same, it looks like having a space in my Parameter Name causes an issue because the space was being replaced with a '_' by the GPString (which seems odd to me), which does not happen when called from a browser.  Changed the Parameter names to have no space and all is well ...

Hi, I'm trying to make a datagrid that autopopulates with a handful of counties. I believe the new featuredatagrid and the querytask would be the best way to do this so I can keep the parameters dynamic as to which counties are in the datagrid. I have two questions about this, how would I go about only returning specific, pre-set results through the querytask (is it through use of the "Where" public property or "ObjectID")? And my second question is, how would I pre-set the featuredatagrid to autozoom to selected Item instead of autozoom to selected being toggle off by default. I can't seem to find that property setter anywhere in the API reference. Thanks for any help. The FeatureDataGrid binds to a GraphicsLayer so there are two approaches you can use.  Either using a FeatureLayer (which inherits from GraphicsLayer) or use a GraphicsLayer and add the Graphics objects in code.  Personally I think if possible the FeatureLayer simplifies things over running a Query and then adding Graphics to the GraphicsLayer, but neither way is more correct than the other. As for using ObjectId property or the Where clause it is really another case of there is no best answer.  I think in general the Where is more standard because the ObjectID could potentially change (like if for some reason data was reloaded into a Feature Class).  If there is not some attribute that is being used (e.g., all counties with population over 1,000,000 or counties with the best BBQ 🙂 - you are in TX right?) you can always use a SQL In clause on the name (Where = "Name In (CountyA, CountyB,...)") This thread may help with how to go about zooming to the location when the user clicks on the item in the FeatureDataGrid. http://forums.arcgis.com/threads/58076-zoom-to-points?p=201782#post201782 Hope that helps ...

Hello everyone, I know it is something related to silverlight i just post it if anybody has answer then he or she can help me. everything is working fine in my application but I noticed that XAP file is getting bigger and bigger I have used silverpdf.dll which size is around 2 mb if i remove it from project than xap file will reduce by 800 kb.but i am using many methods of that dll.I create class library but the xap file is same so any body know that how to add third party dll in reference with out changing xap file size? Please help, Thanks Foram There is no way to do that.  The xap contains all the assemblies you reference.  It needs to be there otherwise your application would not run.  A Silverlight application runs inside the Silverlight plugin on the clients machine.  All assemblies required by the application must, therefore, be downloaded to the client machine.  There are ways to break things into multiple Xap files so it only downloads what it needs when it needs it, but that is a pure (advanced) Silverlight discussion which you could try to search MSDN or other Silverlight sites for. ...

Thanks but inside our network the speed is good but outside it is working slow. I think it is something related to dsl.do you know how to check the issue? Yes I understand that, which is why I think it is your upload speed (meaning the bandwidth you have to upload data to the internet) may be slow.  Internally you probably have 10 MB/s or faster bandwidth.  As I mentioned in my previous post go to a site such as http://speedtest.net/ and just click the Begin Test button it will show you a realistic estimate of both download and upload bandwidth to the internet.  It is not uncommon for some ISPs to only give about 1/10 (or less) upload speed compared to what your download bandwidth is.  So you may have a connection advertised as 15 mb/s (download) which is giving only 1 mb/s upload speed.

Jared, The Except() method is meant to return an IEnumerable<T> of all the elements in an IEnumerable<T> that are not a provided IEnumerable<T> (huh :)).  So the usage is like this   IEnumerable<int> myInts = westTexas.VisibleLayers.Except(new[] {0}); Which returns an IEnumerable<int> of all the values in VisibleLayers Except for 0, which is not really what you want.  The code sample I provided should work to Toggle visibility of a given layer.  You just need to use contains backwards, if .Contains returns false, then pass SetLayerVisibility a value of true         private void ToggleVisibility(int layerId)         {             var westTexas = TabletMap.Layers["West Texas"] as ArcGISDynamicMapServiceLayer;             if ( westTexas == null ) return;               //this will return True if the VsibleLayers includes layerId (is Visible), or False if it is not included (not visible)             bool isVisible = westTexas.VisibleLayers.Contains(layerId);               //This will flip the visbility, if layerId was vsible it rurns it off, if it is not visible it turns it on.             westTexas.SetLayerVisibility(layerId, !isVisible);         } Hope that helps -joe ...

Are your FeatureClasses stored in an enterprise GDB (e.g., Oracle, SQL Server)?  I believe OrderBy functionality is only supported in an enterprise GDB and will not work with a file GDB. ... View more
