[mapguide-users] Get Identity Properties

[Andy Morsell]

There's also some similar code in several places in the viewer files (both
AJAX and Fusion) and some of the sample applications.  This is from
www/mapviewernet/search.aspx.:

	String prop = (String)resProps[i];
                        int propType = features.GetPropertyType(prop);
                        String val = "";
                        switch (propType)
                        {
                            case MgPropertyType.Boolean:
                                val = features.GetBoolean(prop) ? "True" :
"False";
                                break;
                            case MgPropertyType.Single:
                                val = features.GetSingle(prop).ToString();
                                break;
                            case MgPropertyType.Double:
                                val = features.GetDouble(prop).ToString();
                                break;
                            case MgPropertyType.Int16:
                                val = features.GetInt16(prop).ToString();
                                break;
                            case MgPropertyType.Int32:
                                val = features.GetInt32(prop).ToString();
                                break;
                            case MgPropertyType.Int64:
                                val = features.GetInt64(prop).ToString();
                                break;
                            case MgPropertyType.String:
                                val = features.GetString(prop);
                                break;
                            case MgPropertyType.DateTime:
                                val = features.GetDateTime(prop).ToString();
                                break;
                        }

Incase anyone is interested I figured it out... I no longer have to hard
code what the identity property is .

the following will read the feature reader and return the identity property
allowing me now to create more dynamic commands :)

I haven't filled in all the select cases as I'm not sure whats what there.

      while (newFeatReader.ReadNext())
      {
        MgPropertyCollection idProps = new MgPropertyCollection();
        MgResourceIdentifier myRes = new
MgResourceIdentifier(currentLayer.GetFeatureSourceId());

        foreach (MgPropertyDefinition IdPropDef in
newFeatReader.GetClassDefinition().GetIdentityProperties())
          {
            switch (newFeatReader.GetPropertyType(IdPropDef.Name))
            {
              case 1:
             //   Response.Write("1");
                break;
              case 2:
             //   Response.Write("2");
                break;
              case 3:
             //   Response.Write("3");
                break;
              case 4:
              //  Response.Write("4");
                break;
              case 5:
             //   Response.Write("5");
                break;
              case 6:
              //  Response.Write("6");
                break;
              case 7:
                idProps.Add(new MgInt32Property(IdPropDef.Name,
newFeatReader.GetInt32(IdPropDef.Name)));
               // Response.Write("7");
                break;
              case 8:
              //  Response.Write("8");
                break;
              case 9:
              //  Response.Write("9");
                break;
              default:
              //  Response.Write("no valid type");
                break;
            }
          }
        MgSelection sel = new MgSelection();
        sel.AddFeatureIds(currentLayer, currentClassName, idProps);
        String selText = EscapeForHtml(sel.ToXml());

//do additional stuff with feature here....
}
