[mapguide-users] Listing Active selected feature C#

That's a URL encoded equivalent of the XML string.  I'm not sure what you
are doing with the XML after getting it, but take a look at the
HttpUtility.UrlDecode method in the .NET framework (it's in the System.Web
assembly) for details on how to decode the string.

Hi Andy & thank you both - Please let me know if you know anything about
this: 

It seems that my problem with 'listing selected feature' is not a
programming issue rather then something to do with my environment, or I'm
getting it all wrong.

 

When Invoking URL, I'm getting the selected features under the following
string, witch is not a known XML format (getting strange xml characters):  

 

[%3C%3Fxml%20version%3D%221.0%22%20encoding%3D%22UTF-8%22%3F%3E%0A%3CFeature
Set%3E%0A%3CLayer%20id..] Act'.

 

Then getting an unclassified error exception occurred. "An unclassified
exception occurred. Exception occurred in method MgSelection.FromXml at line
158 in file
c:\build_tux_area\mgdev_opensource\common\service\maplayer\Selection.cpp"

 

Strangely, When Invoking Script commands on selected featur I get things OK.


<?xml version="1.0" encoding="UTF-8"?>

<FeatureSet>

<Layer id="0fa0e9e4-0000-1000-8002-0018de8d1ec0">

<Class id="Default:Helkot">

<ID>KwAAAA==</ID>

</Class>

</Layer>

</FeatureSet>

Greg,
Would it be possible for you to post the example to the 
group?  The list should accept plain text file attachments or you could 
paste it into the message body.

I have a C# example where I 
am doing exactly this. I can send you the page via separate means if you are

interested.

I am attempting to get the list of selected parcels by using 

"Invoke URL"
command, passing "$Current Selection" to my 
"listdwfparcels.aspx" page,
through the key & value pair.

I don't 
know what I'm doing wrong, getting unclassified 
exception
"MgSelection.FromXml" . . .

Checking the value of my mgkey 
content "$Current Selection" 
returns:

%3C%3Fxml%20version%3D%221.0%22%20encoding%3D%22UTF-8%22%3F%3E%0A%3CFeatureS

Here 
is portion of the code that I'm using -

String mgSessionId = 
GetParameters()["SESSION"];
String mgSelection = 
GetParameters()["mgkey"];
MgResourceIdentifier 
layerFeatureResource;
MgReadOnlyLayerCollection layers;
MgSelection 
selection;
MgLayer layer;
string layerClassName;
string 
selectionString;
string 
layerFeatureId;
 
 
 try
        
{
  InitializeWebTier();

  MgUserInformation userInfo = new 
MgUserInformation(mgSessionId);
  MgSiteConnection siteConnection = new 
MgSiteConnection();
  siteConnection.Open(userInfo);

  
MgResourceService resourceService 
=
siteConnection.CreateService(MgServiceType.ResourceService) 
as
MgResourceService;
  MgFeatureService featureService 
=
siteConnection.CreateService(MgServiceType.FeatureService) 
as
MgFeatureService;
  MgFeatureQueryOptions queryOptions = new 
MgFeatureQueryOptions();
  
  MgMap map = new 
MgMap();
  map.Open(resourceService, "HaifaMap");
  
if 
(GetParameters()["SESSION"] != "")
{
    selection = new 
MgSelection(map, mgSelection);

<<<<< MY ERROR 
>>>>>
