What do you mean by "paramatrized code" - what are you trying to parameterise?

I used this and it's work with me :

using (MySqlConnection con = new MySqlConnection(ConString))
        {
     con.Open();

 CmdString = "SELECT * FROM database.mytable order by  mycolumn DESC ";
                     MySqlCommand cmd = new MySqlCommand(CmdString, con);
                     MySqlDataAdapter sda = new MySqlDataAdapter(cmd);
                     DataTable dt = new DataTable("mytable");
                     sda.Fill(dt);
                     myDataGrid.ItemsSource = dt.DefaultView;

             }

Thank you for help .

Solution 1

we need to use Func ...

baseEntities dc = new baseEntities();

Func<string> myColumnName = "ColumnName";


     //display data in table in descending order
Mydatagrid.ItemsSource = dc.myentity.OrderByDescending(myColumnName ).ToList();
