title: How to get the value of a combobox from its index?
body: <p>I have a combobox in my C# form. I give it a datasource like that </p>
  
  <pre><code>string selectSql = "SELECT ID, NAME FROM MUSTERI";
  
  SqlCommand comm = new SqlCommand(selectSql, conn);
  SqlDataReader dr = comm.ExecuteReader();
  DataTable dt = new DataTable();
  
  dt.Columns.Add("ID", typeof(string));
  dt.Columns.Add("NAME", typeof(string));
  dt.Load(dr);
  
  combobox.ValueMember = "ID";
  combobox.DisplayMember = "AD";
  combobox.DataSource = dt;
  </code></pre>
  
  <p>I can get item's value (ID which came from database) using <code>Combobox.SelectedValue</code> and item's text (NAME which came from database) using <code>Combobox.SelectedText</code>, but I need to get value of k. items (for exapmle: 4th item's value). How can I get that?</p>
