Listing all the table styles in a drawing

By Virupaksha Aithal

Table styles are stored in named object dictionary under table style dictionary. Below code shows the procedure to traverse the table style dictionary. The code also prints the current table style name.

[CommandMethod("ListTableStyles")]
static public void ListTableStyles() 
{
 
    Document doc = Application.DocumentManager.MdiActiveDocument;
    Database db = doc.Database;
    Editor ed = doc.Editor;
 
    ObjectId tsId = ObjectId.Null;
 
    using (Transaction tr = db.TransactionManager.StartTransaction())
    {
        DBDictionary tsd = (DBDictionary)tr.GetObject(
                                            db.TableStyleDictionaryId,
                                                    OpenMode.ForRead);
 
        TableStyle tStyle = null;
        foreach (DBDictionaryEntry entry in tsd)
        {
            tStyle = (TableStyle)tr.GetObject(entry.Value, 
                                                    OpenMode.ForRead);
 
            ed.WriteMessage(tStyle.Name + "n");
        }
        //current table style
        tStyle = (TableStyle)tr.GetObject(
                                db.Tablestyle, OpenMode.ForRead);
        ed.WriteMessage("Current table style: " + tStyle.Name+"n");
        tr.Commit();
    }
}
