ArcSDE database using a gxFilter?

NigelDsouza

Is there a way of making the user select a .sde file using a IGxDialog ?

Create your own GxFilter and assign to IGxDialog.ObjectFilter.

Suggest deriving from GxFilterWorkspacesClass and just overriding CanDisplayObject method.

e.g. something like:

[ComVisible(true)]
[Guid("...")]
[ProgId("GxFilterSDEWorkspaces.Class")]
public class GxFilterSDEWorkspacesClass : 
     global::ESRI.ArcGIS.Catalog.GxFilterWorkspacesClass
{
     public GxFilterSDEWorkspacesClass() : base()
     {
     }

     //---------------------------------------------------------------------

     public override bool CanDisplayObject( IGxObject OBJECT )
     {
          var  d = base.CanDisplayObject(OBJECT);
          if( !d || !OBJECT.IsValid ) return false;

          if( OBJECT.Category.EqualsI("Folder") ) return true;

          var db = OBJECT as IGxDatabase;
          if( db == null ) return false;

          var ws = db.Workspace;
          if( ws == null || 
               ws.Type != esriWorkspaceType.esriRemoteDatabaseWorkspace ||
               !ws.PathName.EndsWithI(".sde")
          ) return false;

          return true;
     }

     //---------------------------------------------------------------------
     // to avoid compile errors, must override ALL base COM methods.
     //---------------------------------------------------------------------

     public override string Description {
          get { return base.Description; }
     }

     public override string Name {
          get { return base.Name; }
     }

     public override bool CanChooseObject( IGxObject OBJECT, ref esriDoubleClickResult RESULT )
     {
          return base.CanChooseObject(OBJECT, ref RESULT);
     }

     public override bool CanSaveObject( IGxObject LOCATION, string NEWOBJECTNAME, ref bool OBJECTALREADYEXISTS )
     {
          return base.CanSaveObject(LOCATION, NEWOBJECTNAME, ref OBJECTALREADYEXISTS);
     }
}

They will still see all the normal top-level folders GxDialog has, but they will only be able to see and pick connections backed by an .sde file.
