How to rename the dynamic block name.

[TSYUK]

Hello!

I would like to know how to change the dynamic block name.

The below code is good for static block but for the dynamic block, it does not work as i expected.

Please, give me a clue or solution to get dynamic block name changed.

1.   [CommandMethod("RENBLK")]
2.         public void Test()
3.         {
4.             Document doc = AcAp.DocumentManager.MdiActiveDocument;
5.             Database db = doc.Database;
6.             Editor ed = doc.Editor;
8.             using (Transaction tr = db.TransactionManager.StartTransaction())
9.             {
10.                 BlockTable bt = (BlockTable)tr.GetObject(db.BlockTableId, OpenMode.ForRead);
11.                 if (bt.Has("BAT-10"))
12.                 {
13.                     BlockTableRecord btr = (BlockTableRecord)tr.GetObject(bt["BAT-10"], OpenMode.ForWrite);
14.                     btr.Name = "VUU-10";
15.                 }
16.                 tr.Commit();
17.             }
18.         }
