Why you are using ID ASC. You should use Preferance ASC
Datatable.DefaultView.Sort = "Preferance ASC";

Doesn't work. You need to re-assign the DataTable (as shown in solution 6)
I think this is the easiest way to sort a Datatable..

C#
dt.DefaultView.Sort = "Parameter_Name";
dt = dt.DefaultView.ToTable();

Google, my friend, Google.
A very quick search using your subject as the search term lead me to MSDN: Filtering and Sorting Directly in Data Tables[^]

Next time, try google first!

DataTable _dt = new DataTable();
_dt.Columns.Add("Date", typeof(DateTime));
_dt.Columns.Add("Preferance", typeof(int));

_dt.Rows.Add("30/07/2011", 0);
_dt.Rows.Add("02/03/2011", 1);
_dt.Rows.Add("10/12/2011", 2);
_dt.Rows.Add("01/12/2011", 3);

DataView _dv = new DataView(_dt);
_dv.Sort = "Date ASC";

for (int i = 0; i < _dv.Count; i++)
{
    Console.WriteLine(Convert.ToDateTime(_dv[i]["Date"]).ToString("dd/MM/yyyy") + "\t" + _dv[i]["Preferance"]);
}

TableToConvert.DefaultView.Sort = "EVENT_ID";
DataView TableView = TableToConvert.DefaultView;
DataTable NewTable = TableView.ToTable();

The new Table will be sorted

Why do you post an answer to a question from 1 year ago?
That doesn't make sense.
DataTable dtCategory = dsHotelResponse.Tables["Category"].DefaultView.ToTable(true,"ApartmentNo", "Gross").Select("ApartmentNo='" + (roomNo) + "'", "Gross asc").CopyToDataTable();


roomno is use for to filter dynamic values for ApartmentNo change it depend upon your condiction

Did you notice that the question is from July 2011?
Just Use the following code for Reordering Rows in DataTable :
---------------------------------------------------------------
ds.Tables["dtPaymentScheduleTemplateInstallments"].DefaultView.Sort = "[Display Order] ASC";
ds.Tables["dtPaymentScheduleTemplateInstallments"].AcceptChanges();
dtgInstallments.DataSource = ds.Tables["dtPaymentScheduleTemplateInstallments"].DefaultView;

Where :
--------
ds --> DataSet
dtPaymentScheduleTemplateInstallments --> DataTable within DataSet
[Display Order] --> ColumnName on behalf we are Reordering

Did you realise that this question is from 2 years ago and already resolved?
//Sorting the Table
            DataView dv = dt.DefaultView;
            dv.Sort = "ParamValue asc";
            DataTable sortedtable1 = dv.ToTable();
