AutoCAD .NET :: Update Blocks With Attributes Of A Given Layout

Every time I try to update blocks with attributes of a given layout, this only updates the last active layout. example:

I have three layouts: Layout1, Layout2 and Layout3

layout of the three blocks I would need to update the reference but I can Layout1 default that always takes the last active layout. In the following paper space specific code, but as it would to tell a particular layout.

Private Sub UpdateAttributesInDatabase(ByVal db As Database, ByVal blockName As String, ByVal attbName As String, ByVal attbValue As String) Dim psId As ObjectId Dim tr As Transaction = db.TransactionManager.StartTransaction() Using tr Dim bt As BlockTable = DirectCast(tr.GetObject(db.BlockTableId, OpenMode.ForRead), BlockTable) psId = bt(BlockTableRecord.PaperSpace) tr.Commit() End Using UpdateAttributesInBlock(db, psId, blockName, attbName, attbValue) End Sub
