Inserting block reference into table cell

By Virupaksha Aithal

Below code shows the procedure to add block reference to a table cell. Code uses the “Cell. BlockTableRecordId” API to add the block reference to cell.

[CommandMethod("Table_insertBlockReference")]
static public void Table_insertBlockReference()
{
    Database db =
        Application.DocumentManager.MdiActiveDocument.Database;
    Editor ed =
        Application.DocumentManager.MdiActiveDocument.Editor;
    using (Transaction tr = 
        db.TransactionManager.StartTransaction())
    {
        try
        {
            // Prompt the user to select an entity 
            PromptEntityResult ers = 
                        ed.GetEntity("Pick entity ");
 
            if (ers.Status == PromptStatus.OK)
            {
                // Open the selected entity 
                Entity ent = 
                    (Entity)tr.GetObject(ers.ObjectId, 
                                            OpenMode.ForRead);
                if (ent is Table)
                {
                    Table table = (Table)ent;
                    BlockTable btable = 
                        tr.GetObject(db.BlockTableId, 
                           OpenMode.ForRead) as BlockTable;
                    if (btable.Has("test"))
                    {
                        table.UpgradeOpen();
                        //add the block reference to 1,1 cell
                        table.Cells[1, 1].BlockTableRecordId 
                                            = btable["test"];
                    }
                }
 
                tr.Commit();
            }
        }
        catch (System.Exception ex)
        {
            ed.WriteMessage(ex.Message);
            tr.Abort();
        }
    }
}
