How to set location for AttributeReference

Hi, I'm here to answer my questions. Hope everybody help please
when i insert a block into autocad drawing. I have a custom edit, it changes the position of position. I have repositioned the block but an error has appeared. attributes do not automatically move by block
below is my image and code
this is when i insert

this is the result i want.

sample my code: I was able to handle it with ed.Command("ATTSYNC", "Name", blockNameInsert); this is probably a bad idea.

#region Insert block WallVertDowelType3 // Create a new block reference and add it to the current space using (BlockReference br_Insert = new BlockReference(geoPosition, blockTable[blockNameInsert])) { br_Insert.Layer = genLayer; br_Insert.ScaleFactors = getScale; br_Insert.Rotation = misRotation; // insert block WallVertDowelType3 vào CurrentSpaceId BlockTableRecord btrCurrentSpace = tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite) as BlockTableRecord; btrCurrentSpace.AppendEntity(br_Insert); tr.AddNewlyCreatedDBObject(br_Insert, true); #region Set Attribute[] of Block Reference | if (btr.HasAttributeDefinitions) BlockTableRecord blockInsert = tr.GetObject(blockTable[blockNameInsert], OpenMode.ForRead) as BlockTableRecord; foreach (ObjectId oid_ATB in blockInsert) { DBObject dBObject = tr.GetObject(oid_ATB, OpenMode.ForRead); if (dBObject is AttributeDefinition) { AttributeReference attRef = new AttributeReference(); // Add the attribute to the block reference AttributeDefinition attDef = dBObject as AttributeDefinition; attRef.SetAttributeFromBlock(attDef, br_Insert.BlockTransform); //attRef.Position = attDef.Position.TransformBy(br_Insert.BlockTransform); double temp_DIA = DIA.Contains("D") ? Convert.ToDouble(DIA.Split('D')[1]) : Convert.ToDouble(DIA); switch (attRef.Tag) { case "xxx": attRef.TextString = "xxx"; break; } // Add attribute to block reference br_Insert.AttributeCollection.AppendAttribute(attRef); tr.AddNewlyCreatedDBObject(attRef, true); } } #endregion #region Set Custom[] of Block Reference Dynamic | if (bref.IsDynamicBlock) DynamicBlockReferencePropertyCollection DBRPCollection = br_Insert.DynamicBlockReferencePropertyCollection; foreach (DynamicBlockReferenceProperty DBRProperty in DBRPCollection) { switch (DBRProperty.PropertyName) { case "xxx": DBRProperty.Value = canhB; break; } } br_Insert.Position = geoPosition; // error generated attribute is not in the correct position. Temporarily fixed with `ATTSYNC` #endregion } #endregion ed.Command("ATTSYNC", "Name", blockNameInsert); //still usable but not optimal in terms of performance. i need another way

Instead of changing Position property of a BlockReference, you use Matrix3d.Displacement() to transform a block for moving it, if the block reference owns attributes:

var mt=Matrix3d.Displacement(blk.Position.GetVectorTo([newLocation]);

blk.TransformBy(mt);
