Binding linq result to list box

Question

Hi , i have the following piece of code, that for some reason that i'm unaware of, doesn't populate the LINQ resultset to the listbox (and there are many results in this list), however, i bind it to the original datatable, it works well. any ideas:

 DataTable t = _partitionsDataSet.Tables[0];

                var customizedPartitions = from r in t.AsEnumerable()
                                 select new 
                                            {
                                                Name = string.Format("{0}[{1}]", r["Name"], r["UserName"]),
                                                BlobId = r["BlobId"].ToString()
                                            };

                if (customizedPartitions.Count() > 0)
                {
                    _dataView.Sort = "Name";
                    listBoxPartitions.DisplayMember = "Name";
                    listBoxPartitions.ValueMember = "BlobId";
                    listBoxPartitions.DataSource = customizedPartitions;
                }

Answer 1

You have to call the listBoxPartitions.DataBind() method after setting the data source.

Answer 2

it seems like that if i bind to "customizedPartitions.ToList()" its all works well. interesting..any comments why?
