[mapguide-users] Zoom To Selection

[Warren Medernach]

Hi Michael,

MapGuide does have this functionality.  In the Basic WebLayout, if you
create a 'Search', it provides the ability to zoom to a result of the
search.  Check out the Sheboygan sample and the SheboyganAsp WebLayout.

 

In the Fusion Layouts, check out the Search Widget for the same
functionality.

Hope this helps

The capability to zoom to a feature (such as by clicking a feature in a
list of features found by a search) should be a basic capability of a
GIS system - why doesn't Mapguide and fusion have it out of the box?

may code is


      NameValueCollection serverVars = Request.ServerVariables;
      String strServerVars = "";
      foreach (String str in serverVars.AllKeys)
      {

          strServerVars += "<br>" + str;

      }
      String platform = serverVars["SERVER_SOFTWARE"];
      String queryStr = serverVars["QUERY_STRING"];
      string queryStr1 = serverVars["Form"];
      NameValueCollection requestParams = Request.HttpMethod == "POST" ?
Request.Form : Request.QueryString;
      String sessionId = Request.QueryString["SESSION"];
      //String sessionId = Request.QueryString["SESSION"]; ;

      string realPath = Request.ServerVariables["APPL_PHYSICAL_PATH"];
      String configPath = realPath + "webconfig.ini";
      MapGuideApi.MgInitializeWebTier(configPath);

      MgUserInformation userInfo = new MgUserInformation(sessionId);

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

      MgResourceService resService =
(MgResourceService)siteConnection.CreateService(MgServiceType.ResourceSe
rvice);
      MgFeatureService featureService =
(MgFeatureService)siteConnection.CreateService(MgServiceType.FeatureServ
ice);

      MgMap map = new MgMap();
      map.Open(resService, "oramap");


      MgFeatureQueryOptions nameQuery = new MgFeatureQueryOptions();

//nameQuery.SetFilter(ConfigurationManager.AppSettings["FieldToFilter"]
+
"=" + Globals.gURLParam);
      nameQuery.SetFilter("PARCEL_ID" + "=" + "670_111");
      MgResourceIdentifier parcelId = new
MgResourceIdentifier("Library://Orasample/resora.FeatureSource");
      MgFeatureReader featureReader =
featureService.SelectFeatures(parcelId, "GEOM_TABLE", nameQuery);

      //Highlight the query result on the map
      MgSelection selection = new MgSelection(map);
      MgLayer layer = (MgLayer)map.GetLayers().GetItem("GEOM_TABLE");


      featureReader = featureService.SelectFeatures(parcelId,
"GEOM_TABLE", nameQuery);
      selection.AddFeatures(layer, featureReader, 0);
    String selectXML = selection.ToXml();
      selection.Save(resService, "oramap");
      Page.ClientScript.RegisterStartupScript(Page.GetType(), "test",
"select('" + selectXML + "');", true);
}
