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.
