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)
{
ed.WriteMessage("\n Could Not Bind!" + ee);
}
}
}
catch (Autodesk.AutoCAD.Runtime.Exception ee)
{
ed.WriteMessage("\nFailed!" + ee);
}

}
