however, i'm able load textbox , can't seem listview populate. here's have far:

private void opentoolstripmenuitem_click(object sender, eventargs e)     {         if (openfiledialog1.showdialog(this) == system.windows.forms.dialogresult.ok)         {             using (streamreader reader = new streamreader(openfiledialog1.filename))             {                 accounttext.text = reader.readline();                 if (transactionlist.items.count == 0)                {                    foreach (listviewitem item in transactionlist.items)                    {                        stringbuilder mystring = new stringbuilder();                        foreach (listviewitem.listviewsubitem listsub in item.subitems)                        {                            mystring.append(string.format("{0}\t", listsub.text));                        }                        reader.read();                    }                    reader.readtoend();                }             }         }     } 

any tips appreciated.

you need split string '\t' character, return string[]. add these array items listview.

string[] items = reader.readline().split('\t'); foreach (var item in items) {     var listviewitem = new listviewitem(item);     transactionlist.items.add(listviewitem);     }
