Re-2: [mapguide-users] Selection and Zoom Problem

This name will vary with each dataset that you use this function for.
 
It may be more robust to take a generic approach, inspecting the class
definition -- GetClassDefinition() -- to determine the identity property
-- GetIdentityProperties(), IndexOf(), GetName().  I don't think that
MapGuide supports multiple identity columns yet (could be wrong) so you
should be safe just getting the definition of the first one.
 
You can find how to work with these calls here:
https://mapguide.osgeo.org/nonav/docs/webapi/d6/ddc/class_mg_feature_rea
der.html
 
The only one that is difficult to find is GetName(), which is a method
of the MgPropertyDefinition's parent class, MgProperty.

Thanks Andy!

 

I had already tried this, without success.

But I found the error:

When I change "Key" to "Autogenerated_SDF_ID", it works:

 

Select Case features.GetPropertyType("Autogenerated_SDF_ID")

                    Case MgPropertyType.Int32

                        Selection.AddFeatureIdInt32(layer,
featureClassName, features.GetInt32("Autogenerated_SDF_ID"))

                    Case MgPropertyType.String

                        Selection.AddFeatureIdString(layer,
featureClassName, features.GetString("Autogenerated_SDF_ID"))

                End Select

            End If
