Bind Xref's in C#

[joelkarr]

I am trying to create a utility for AutoCAD to bind all xrefs. I have ran into trouble with E-transmit when an xref is unloaded. I have found that you can do a switch for XREFSTATUS and am able to get all resolved xref's. It seems that when I run the code it says they are bound but when I open xref manager they are not.

Is there something similar to editing attributes where I need to open the xref for editing and then close it? I have seen an xrefeditenable command


Below is my current code setup. I plan on making a collection for each XREFSTATUS and working with it accordingly.

[CommandMethod("Bindem")]
        public void bindXref()
        {
            
            Document doc = acad.DocumentManager.MdiActiveDocument;
            Editor ed = doc.Editor;
            Database db = doc.Database;
            Transaction tr = doc.TransactionManager.StartTransaction();


            try
            {


                using (tr)
                {
                    ObjectIdCollection btrCol = new ObjectIdCollection();
                    XrefGraph xrgraph = doc.Database.GetHostDwgXrefGraph(false);
                    // look at all Nodes in the XrefGraph.  Skip 0 node since it is the drawing itself.
                    for (int i = 1; i < (xrgraph.NumNodes - 1); i++)
                    {
                        XrefGraphNode xrNode = xrgraph.GetXrefNode(i);

                        BlockTableRecord btr = (BlockTableRecord)tr.GetObject
                            (xrNode.BlockTableRecordId, OpenMode.ForWrite);
                        
                        switch (xrNode.XrefStatus)
                        {
                            //if it is a resolved xref, then add to collection to be bound
                            case Autodesk.AutoCAD.DatabaseServices.XrefStatus.Resolved:
                                btrCol.Add(btr.ObjectId);
                                ed.WriteMessage("\n Xref added: " + btr.Name);
                                break;
                            case Autodesk.AutoCAD.DatabaseServices.XrefStatus.Unloaded:
                                
                                break;
                            case Autodesk.AutoCAD.DatabaseServices.XrefStatus.FileNotFound:
                                
                                break;
                            case Autodesk.AutoCAD.DatabaseServices.XrefStatus.NotAnXref:
                                
                                break;
                            case Autodesk.AutoCAD.DatabaseServices.XrefStatus.Unreferenced:
                                
                                break;
                        }

                    }
                    ed.WriteMessage("\nTrying to bind");
                    try
                    {
                        //if there are xref id's in btrCol then attempt to bind each one
                        if (btrCol.Count > 0)
                        {
                            foreach (ObjectId id in btrCol)
                            {
                                db.BindXrefs(btrCol, true);
                                ed.WriteMessage("\nBound");
                            }
                        }

                    }
                    catch (Autodesk.AutoCAD.Runtime.Exception ee)
                    {
