I'm trying to programmatically insert a block Reference from a pre-existing drawing into the current drawing.
In Block Table ID created.
In the current drawing the Block Reference not visible. But while selecting and erasing it shows one entity.
And in Block Table the block preview also not shown.
Please give me your suggestions and comments.

Code:
public void InsertBlock() // This method can have any name
{
Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument; //Stores the active document
Editor ed = doc.Editor; //Stores the document's editor
Database dtb = ed.Document.Database; //Stores the database from the editor
Transaction tr = dtb.TransactionManager.StartTransaction(); //Start a transaction with the document's database
DocumentLock docLock = doc.LockDocument();
using (tr)
using (docLock)
{
BlockTableRecord btr = (BlockTableRecord)tr.GetObject(dtb.CurrentSpaceId, OpenMode.ForWrite); //Opens the block table record so you can write to it
BlockTableRecord newBlockDef = new BlockTableRecord(); //Creates a new record in the block table
BlockTable blockTable = (BlockTable)tr.GetObject(dtb.BlockTableId, OpenMode.ForWrite); //Opens the block table so it can be written to
//Pointing new block to correct drawing file
newBlockDef.Name = "Handhole";
newBlockDef.PathName = "D:\\Test\\Data\\Blocks\\Handhole.dwg";
blockTable.Add(newBlockDef); //Adds the block table record to the block table
BlockReference newBlock = new BlockReference(new Point3d(0, 0, 0), newBlockDef.ObjectId); //Insert a block reference with the newly created block
btr.AppendEntity(newBlock); //Inserts the block into the current space (Model or Paper) via the block table record
//Updates the Transaction with all new database objects
tr.AddNewlyCreatedDBObject(newBlockDef, true);
tr.AddNewlyCreatedDBObject(newBlock, true);
tr.Commit(); //Applies all changes made as part of the current transaction
tr.Dispose();
}
