[mapguide-users] select the location on map

[Ivan Milicevic]

Hello Susan,

 

Here is C# code for selection, it's pretty same as PHP. 

 

MgSiteConnection siteConnection = null;

    InitializeWebTier();

 

    MgUserInformation userInfo = new MgUserInformation(mgSessionId);

    siteConnection = new MgSiteConnection();

    siteConnection.Open(userInfo);

    MgResourceService resourceService =
siteConnection.CreateService(MgServiceType.ResourceService) as
MgResourceService;

    MgFeatureService featureService =
siteConnection.CreateService(MgServiceType.FeatureService) as
MgFeatureService;

    MgMap map = new MgMap();

    map.Open(resourceService, "1"); //opening map with name "1"

 

    MgFeatureQueryOptions queryOptionsObjekti = new
MgFeatureQueryOptions();

    MgAgfReaderWriter geometryReaderWriter = new MgAgfReaderWriter();

    MgSelection selection = new MgSelection(map);

 

    //Defining layer and feature source

    MgLayer layerObjekti = GetLayerByName(map, "OBJEKTI");

    MgResourceIdentifier featureResIdObjekti = new
MgResourceIdentifier("Library://PROJEKTI/" + TIMgisUser +
"/PODACI/OBJEKTI.FeatureSource");

 

    //Creating feature filter, this is very important step!

    string filter = "ID=" + idO;

 

    queryOptionsObjekti.SetFilter(filter);

    MgFeatureReader featureReaderObjekti =
featureService.SelectFeatures(featureResIdObjekti, "OBJEKTI",
queryOptionsObjekti);

    selection.AddFeatures(layerObjekti, featureReaderObjekti, 1);

    selection.Save(resourceService, "1");

 

    StringReader stream = new StringReader(selection.ToXml());

    string selectionXml = selection.ToXml();

    featureReaderObjekti.Close();

    map.Save();

 

    //Here, you call javascript function and pass the selection var

    Response.Write("<script>select('" + selectionXml + "');</script>");

 

//This is javascript function that set's the selection from code and do
the refresh.

function select(xml)

{

parent.mapFrame.SetSelectionXML(xml);

parent.mapFrame.ExecuteMapAction(10);

}
